INTRODUCTION
INTRODUCTION
HP Tuners, LLC
VCM Suite is a comprehensive tuning tool that allows performance tuning and
diagnostics, whether you want to improve the fuel economy of your daily driver or
maximize your performance on the race track.
The suite has two components:
￭ VCM Editor allows users to adjust many of the parameters that control the
operation of the engine and transmission.
￭ VCM Scanner allows users to monitor, log, and review key data that provides
insight into the effectiveness of the vehicle's current tune. With such insight, a
skilled tuner can return to VCM Editor and further refine the tune.
This guide covers the use of VCM Scanner.
WHAT'S NEW IN VCM SCANNER?

Recent changes to VCM Scanner are listed below, For a historical list of changes, see
the VCM Scanner Changelog.
VCM SCANNER 5.0
GENERAL
￭ MPVI3 and RTD gen 3. VCM Scanner now supports our latest generation of
interface devices.
￭ Multi-language support. It's a work in progress, but we have begun to translate
portions of the VCM Suite user interface. See Selecting the Displayed Language
(Page 22) for more information.
￭ Improved Vehicle Profile Editor. You can now load and save vehicle profiles and
import them from log files. Doing channel configuration for vehicles that are
located remotely just got a whole lot easier. See Vehicle Profiles (Page 37) for more
information.

GETTING STARTED WITH VCM SCANNER

1. It is recommended you have the following before you begin using VCM Scanner:
￭ An account on hptuners.com.
￭ An interface device from HP Tuners that has been registered.
NOTE: For detailed explanations of all of these topics (and more), see the
VCM Suite Getting Started Guide.
2. When you are ready to begin, connect to the vehicle:
a. Connect your laptop to the vehicle. See Connecting to a Vehicle (Page 23).
NOTE: Certain vehicles may require special cables to connect to the

vehicle.
b. If VCM Editor is open, close it now.
c. Open VCM Scanner.
d. Turn the vehicle ignition to a position other than OFF. (The engine can be
running or stopped. But, the vehicle must supply power to the OBD-II port.)
e. Click the icon in the toolbar to open a data connection to the vehicle.
3. ALWAYS check the vehicle for diagnostic trouble codes (DTCs) and resolve any
issues reported before you do anything else. If there is a mechanical issue with the
vehicle, it may affect performance and any performance data you want to monitor
could be impacted. This makes it very difficult to tune the vehicle effectively.
a. Click . The Diagnostics & Information window appears.
b. Click Read DTCs. VCM Scanner will query the vehicle for diagnostic
information.
See Reading and Clearing DTCs (Page 29) for more information.
HP Tuners, LLC
INTRODUCTION
4. While connected to the vehicle, you can do a quick initial scan of its performance
an emissions behavior using VCM Scanner's default settings. Follow these steps:
a. Click to start a live scan.
b. To stop scanning, click .
c. If you want to save this scan data to a log file, click .
See Live Scanning and Logging (Page 33) for detailed instructions.
5. Once you have a basic familiarity with the scanner interface, it is likely that you will
want to start customizing it for the job at hand. VCM Scanner is capable of
retrieving, displaying, and logging a broad range of data from a variety of sources.
Creating the best setup for a particular troubleshooting or tuning task typically
includes the following steps:
a. Add channels to retrieve the data you want to view and/or log. Most channels
are data received through the vehicle's OBD-II diagnostics port. But, you can
also add data received from an external device connected to your HP Tuners
interface or to your computer's serial port. See Channels (Page 65) for instruc-
tions.
b. Modify the displayed layouts (gauges, graphs, and charts) to include the
parameters you need to see. Refer to Layouts (Page 99) for more information.

DIAGNOSTICS &
INFORMATION
HP Tuners, LLC
The Diagnostics & Information window displays the emissions monitor readiness
status for the connected vehicle and can be used to view and clear Diagnostic Trouble
Codes (DTCs).
To open this window, do one of the following (while connected to the vehicle):
￭ In the toolbar, click .

￭ in the menu bar, select Vehicle > Diagnostics & Info.
NOTE: On some older vehicles that use the ISO or SCI protocols, you cannot check
DTCs while you are scanning.
HP Tuners, LLC
READING AND CLEARING DTCS

When you begin tuning a new vehicle, ALWAYS check the vehicle for diagnostic trouble
codes (DTCs) and resolve as many as you can before you do anything else. If there is a
mechanical issue with the vehicle, it may affect performance and any performance
data you want to monitor could be impacted. This makes it very difficult to tune the
vehicle effectively.
IMPORTANT: Reading a vehicle's current tune will clear all DTCs, resulting in the
loss of the troubleshooting information they contain. DO NOT read the tune until
you have checked for DTCs here and resolved or made note of any issues
reported.
Follow these steps:
1. Physically connect your laptop to the vehicle. See Connecting to a Vehicle (Page
23).
2. If VCM Editor is open, close it now.

3. Open VCM Scanner.
4. Turn the vehicle ignition to a position other than OFF. (The engine can be running
or stopped. But, the vehicle must supply power to the OBD-II port.)
5. Click the icon in the toolbar to open a data connection to the vehicle.
6. Click . The Diagnostics & Information window appears.
7. Click Read DTCs. VCM Scanner will query the vehicle for diagnostic information.
When finished, any DTCs detected will appear in the top half of the window.
8. Some vehicles report additional "freeze frame" data for individual DTCs. If this data
is available for your vehicle, it can be viewed on the Freeze Frame tab.
9. Use the provided information to resolve as many issues as possible before tuning
the vehicle.
HP Tuners, LLC
10. If desired, you can click Clear DTCs to tell the vehicle that the issue has been
repaired.
NOTE: Clearing DTCs resets the emissions monitors. This will cause the
vehicle to fail emissions testing until it completes the tests performed by the
emissions monitors. These tests typically take several drive cycles to
complete.
NOTE: If an issue has not been successfully repaired, a cleared DTC will be
reported again.
HP Tuners, LLC
VIEWING FREEZE FRAME DATA

Some vehicles can report freeze frame data captured at the moment a DTC is set. This
may be useful if you are trying to troubleshoot a DTC on a vehicle that supports this
function.
To see the freeze frame data for reported DTCs:
1. While connected to the vehicle, navigate to the Diagnostics & Information window.
2. Select the Freeze Frames tab.

3. Click Read Freeze Frames.
HP Tuners, LLC
CHECKING EMISSIONS MONITOR STATUS

In many countries, a vehicle's on board diagnostics must complete government-
specified self testing before they are allowed to report that the vehicle's emissions
controls are functioning within legal limits.
Vehicles will not pass emissions testing until the required self tests are competed.
Moreover, these "emissions monitors" reset whenever you clear DTCs, when the
battery is replaced, and after some types of major maintenance. So, the vehicle will
need to complete the self tests again after any of these events.
Follow these steps to verify that the emissions monitor tests have been completed:
1. Physically connect your laptop to the vehicle. See Connecting to a Vehicle (Page 1).

4. Start the engine.
6. Click . The Diagnostics & Information window appears.
7. Click Read DTCs. VCM Scanner will query the vehicle for diagnostic information.
When finished, the status of the emissions monitors will appear in the lower half
of the window.
The three tests in the left column are run continuously and should indicate
completion shortly after the engine is started. The tests in the right column may
take several drive cycles to complete.
NOTE: If you are using VCM Suite version 4.13 or later, you can use the Drive
Cycle Panel to help ensure that the tests in the right column are completed as
quickly as possible.
HP Tuners, LLC
LIVE SCANNING AND LOGGING
LIVE SCANNING AND

LOGGING
HP Tuners, LLC
When paired with your HP Tuners interface device, VCM Scanner is capable of reading
live data off the vehicle and displaying it on various gauges, charts, and graphs in real
time.
When you are finished scanning, you can save your scan data to a log file for later
review and analysis.
SCANNING CONFIGURATION
Although you can do a quick scan with the default settings, you can tailor the
information retrieved from the vehicle to suit the task at hand. A little configuration
can give you much better troubleshooting information and can make the presentation
of that information much more suited to your personal working style.
Follow these steps:
1. When preparing to scan a new vehicle, connect to the vehicle briefly before you
begin configuration. This will allow VCM Scanner to create a profile for the vehicle
and attempt to load vehicle-specific parameters. See Creating a Vehicle Profile
(Page 38) for instructions.
2. Add channels to retrieve the data you want to view and/or log. Although there are
a few standard channels set up by default, you will need to add a channel for any
additional parameter that you wish to monitor and any external device connected
to your HP Tuners interface or to your computer's serial port. See Channels (Page
65) for instructions.
3. Modify the displayed layouts (gauges, graphs, and charts) to include the
parameters you need to see. Refer to Layouts (Page 99) for more information.
HP Tuners, LLC
SCANNING PROCEDURE
To do a live scan of the vehicle with the current configuration:
1. Connect your HP Tuners interface device to your laptop and then connect the
interface to the OBD-II port on your vehicle. See Connecting to a Vehicle (Page 23)
for details.

6. When VCM Scanner has finished connecting, click to start scanning.
7. (VCM Suite version 4.13 or later) While scanning, you can insert a marker at the
current time index:
￭ Press M on your keyboard to insert a marker without a comment.

￭ Press C to insert a marker and add a comment.
When playing back a log file, markers appear as green bars in the timeline. Longer
key presses will generate wider bars. See The Timeline (Page 61).
NOTE: Although comments are saved in the log file, version 4.13 can't display
them yet. Look for this feature to be added in a future release.
8. To stop scanning, click .
9. If you want to save this scan data to a log file, click .
HP Tuners, LLC
GENERATING A LOG FILE

Scanned data can be saved to a log file, which can be opened later for further review
and analysis. There are two ways to generate such a file:
￭ Save a live scan.

￭ Configure your interface device for standalone data logging.
SAVING A LIVE SCAN
NOTE: Due to changes in file content, log files saved in VCM Suite version 4.13 (and
later) cannot be opened in versions older than 4.13.
Follow these steps to generate a log file from a live scan:
1. Ensure that your channel setup includes all the parameters you want to capture in
the log. See Channels (Page 65).
2. Connect to the vehicle and perform a live scan. See Scanning Procedure (Page 35)
3. When the scan is complete. Click in the toolbar.
4. Enter an appropriate file name and click Save.
STANDALONE DATA LOGGING

Standalone data logging allows you to save a log file to the memory of your HP Tuners
interface device when the device is not connected to your computer. For the full
procedures associated with generating such a log file, see Standalone Data Logging
(Page 45).
In short, however, the steps are as follows:
1. Connect your interface device to your computer.
2. In VCM Scanner, configure your interface for standalone data logging.
HP Tuners, LLC
3. Disconnect your interface device from your computer and connect it to the
vehicle.
4. Use the buttons on the device to start and stop logging.
NOTE: The MPVI2 and newer interface devices also support programmed start
and stop triggers based on driving events.
5. Disconnect the device from the vehicle and reconnect to your computer.
6. In VCM, Scanner, retrieve the log files from the device.
VEHICLE PROFILES
Each vehicle make and model has its own unique set of parameters. The list of
parameters for one manufacturer's vehicles will be completely different than the list
for a different manufacturer's vehicles. Moreover, some vehicles that share a make
and model may support different parameters and channels if their controllers have
different operating system IDs.
When you connect to a new vehicle, VCM Suite will create and store a new "Vehicle
Profile" in order to save the channel and parameter setup you implement for that
vehicle. When you connect to the vehicle again, the correct profile will be auto-
matically selected.
(VCM Scanner version 4.13 and later) If a vehicle is located remotely, you can obtain
its profile from a user who has access to the vehicle. This allows you to create a
channel configuration for remote customers. There are two ways to do this:
￭ Profiles can be saved to file and exchanged between users of VCM Scanner. See
Saving a Vehicle Profile to File (Page 41) for instructions.
￭ Profiles can be imported from a data log performed on the vehicle. See Importing a
Vehicle Profile from a Data Log (Page 43).
HP Tuners, LLC
NOTE: If a vehicle misreports or doesn't report its operating system ID or VIN, it
may be necessary to manually enter these in the vehicle profile in order to help
VCM Scanner load the appropriate parameter set. See Manually Entering an OS
ID or VIN (Page 40).
When you are not connected to a vehicle, you can switch between profiles so that
VCM Scanner loads the parameter set for the vehicle you wish to work with. See
Selecting a Stored Vehicle Profile (Page 41).
NOTE: Only OBD channels are saved in vehicle profiles. Since external channels
are independent of the vehicle, they will be available with all vehicles
CREATING A VEHICLE PROFILE

A vehicle profile is created automatically the first time you establish a data connection
to a new vehicle. If you want to customize channel setup, connect to the vehicle
briefly before you begin and poll the vehicle for the latest parameters. This helps
ensure that VCM Scanner displays an accurate list of parameters available for your
vehicle.
Follow these steps:
1. Physically connect your laptop to the vehicle. See Connecting to a Vehicle (Page
23).

6. When VCM Scanner has finished connecting, select Vehicle > Repoll for
Supported Parameters in the menu bar. This will update the vehicle profile with
HP Tuners, LLC
any additional parameter changes not included in the default profile for the type
of vehicle you are connected to.
NOTE: We recommend you check for DTCs before you begin tuning a new
vehicle. This is a good time to do so. See Reading and Clearing DTCs (Page 29)
for instructions.
7. If desired, you can now click to close the data connection and then disconnect
your laptop from the vehicle.
I STILL SEE ONLY SAE PARAMETERS!

There are a couple of reasons that you might still be limited to SAE parameters after
the vehicle profile has been created:
￭ The vehicle is not supported by VCM Suite.

￭ The vehicle is not reporting its VIN or the OS IDs of its controllers correctly. In
most cases, this means that the operating system has been scrambled for security.
For vehicles that are not correctly reporting VIN or OS ID, try the following:
￭ If you know the vehicle's actual VIN or the actual OS IDs of its controllers, you can
enter them manually. See Manually Entering an OS ID or VIN (Page 40).
￭ Define "fallback" OS IDs that will apply to any vehicle whose profile is missing an
OS ID or has an incorrect OS ID. But, these are not vehicle-specific. See Advanced
Channel Properties (Page 94).
HP Tuners, LLC
MANUALLY ENTERING AN OS ID OR VIN

Each operating system for vehicle controllers supports its own unique set of
parameters. VCM Scanner needs the correct operating system IDs for your vehicle's
controllers to load parameter definitions that are appropriate for the vehicle.
If the vehicle does not properly report its VIN or the operating system ID for one of its
controllers, VCM Scanner will be unable to determine what parameter definitions to
load. In most cases, this means that the operating system has been scrambled for
security.

STANDALONE DATA
LOGGING
HP Tuners, LLC
Standalone Data Logging lets you log data directly to internal storage of your MPVI Pro,
MPVI2/2+, or MPVI3 without being tethered to a laptop. It is now easier than ever to
collect data while driving. Once the feature is configured, you can start and stop
recording with the simple press of a button.
MPVI PRO STANDALONE DATA LOGGING

The standalone data logging feature of the MPVI Pro is available for late model GM
vehicles only.
SETUP
Follow the steps below to set up the standalone datalogging feature for the first time
on a new vehicle or when switching from another vehicle:
1. Put the vehicle's ignition in the ON/RUN state
2. Connect the MPVI Pro to your vehicle's OBD-II port and to your laptop's USB port.
4. Click the icon in the toolbar.
5. Ensure that channels that you wish to log are listed in the Channel display (add or
delete channels as necessary).
6. (Optional) Click to save your channel configuration for later use.
7. In the menu bar select Vehicle > MPVI Pro Data Logging. The MPVI Pro Standalone
Data Logging Functions window appears.

logging will begin when ANY of the conditions are met.
￭ Short Button Press. If this box is checked, a short press of the BT button on
the device will trigger the start of logging. If this box is not checked, a short
button press will not trigger logging start.
￭ Instantaneous Acceleration. If this field is populated, logging will start when
the vehicle reaches the specified acceleration.
￭ Sustained Acceleration. If both of these fields are populated, logging will start
when the vehicle sustains the specified acceleration for the specified number
of seconds (for example, 0.05 G for 1 second).
HP Tuners, LLC
NOTE: If you are using an OBD extension cable, we recommend not using the
accelerometer G-forcestart triggers. The interface device is only secure when
it is plugged directly into the vehicle’s OBD port. If the device is connected via

desired. The OR Trigger Group allows you to set numerous conditions. Data
logging will stop if ANY of these conditions are met. The AND Trigger Group allows
you to set multiple conditions that must ALL be true in order for the data logging
to stop.
￭ Short Button Press. If this box is checked, a short press of the BT button on
the device will trigger the stop of logging. If this box is not checked, a short
button press will not stop logging.
￭ Sustained Acceleration. If both of these fields are populated, logging will stop
when the vehicle drops below the specified acceleration for the specified
number of seconds (for example, 0.05 G for 1 second).
￭ RPM. If both of these fields are populated, logging will stop when the vehicle
drops to the specified RPM or below for the specified number of seconds.
5. When finished, click the Set Triggers button near the bottom of the window.
GENERATING A LOG
1. Disconnect the interface device from your computer. Also ensure that the device
is not connected to any application (TDN, TrackAddict, etc.) via Bluetooth ® .
2. It can take up to two minutes after you disconnect for the device to be ready for
standalone data logging. If you need to start a log sooner, you can force it to reset
by unplugging it from the vehicle's OBD-II port.
3. Plug the device into the OBD-II port of the vehicle you wish to log.
4. Start the engine or place the vehicle on the ON/RUN state without starting the
engine. This will provide power to the device.
HP Tuners, LLC
5. Data logging should start automatically about five to ten seconds after the
configured trigger conditions are met. Once data logging is fully active, the amber
OBD light will flash.
NOTE: The first time you log a particular vehicle, allow an additional five
seconds for the system to initiate. If it takes longer than twenty seconds to
start, please submit a support ticket and attach a copy of the Infolog.
6. Data logging will stop automatically when the configured stop triggers are met.
Alternately, pressing the BT button will perform a quick stop and discontinue
logging data (some devices may require a firmer button press than others).
CAUTION: Do not unplug your interface device without properly stopping

the data logging. Doing so will result in some loss of data.
NOTES
￭ Do not connect to VCM Suite, TDN, or TrackAddict while Standalone Data Logging is
running. If you do so, the data logging software will turn off and stop recording.
Data collected up to that point will be saved.
￭ If the data logging fails during startup (for example, if the vehicle’s ignition is
turned off), logging will abort and the device will wait for another start trigger.
￭ During startup, the OBD and Host lights will flash and may occasionally pause. This
is normal.

CHANNELS
CHANNELS
HP Tuners, LLC
All data input into VCM Scanner is defined by "channels."
￭ If you want to display any value on any layout display (Gauge/Graph/Chart vs.
Time), you must have a channel that supplies the data.
￭ If you want to use a Math Parameter, each variable used in the math parameter will
also require a channel to supply the data.
Many channels are pre-defined (you see some of these in action when you do a quick
scan without adding channels). However, adding an external sensor input or an input
based on a parameter that the vehicle's controller does not broadcast will require that
a channel be added to support the input.
The Channels list displays the currently-defined channels. Use this interface add,
configure, and remove channels.
USING THE CHANNELS LIST

The Channels list is used to add, configure, and remove the "channels" that supply data
to the VCM Scanner application.
By default, it appears on the left side of VCM Scanner's main window.
HP Tuners, LLC
CHANNELS
But, if you click the pin icon in the upper-right corner of the display, it will auto-hide
when you are not using it.
Click the Channels tab on the left when you want to see it.
CHANNEL ICONS
The icons in the left column indicate the type of each channel:
A polled parameter. Although the vehicle's controller can provide this

information, VCM Scanner has to ask the controller to provide it. This adds
processing load to the system. So, adding a large number of these to the
channel list could potentially slow down the rate at which scan data is received.
A broadcast parameter. The vehicle's controller is constantly broadcasting

this parameter, whether VCM Scanner asks for it or not. Therefore, adding
these to the channels list does not impact system performance.
An unsupported parameter. The controller in the current vehicle cannot

provide this parameter.
An external input. The parameter is provided by an external device (typically a

sensor) connected to your computer through one of the following:
￭ The computer's serial (or USB) port.
￭ The EIO Interface for an MPVI Pro.
￭ The Pro Link cable for an MPVI2.
￭ The Pro Link+ cable for an MPVI2+or MPVI3.
External inputs do not impact system performance.

￭ The vehicle's OBD-II diagnostics port. All HP Tuners interface devices are capable of
collecting data from this port. But, the available parameters differ from vehicle to
vehicle and some will not be sent unless you ask the vehicle for them. See Adding
OBD Port Channels (Page 71) for more information.
￭ External analog inputs connected to an MPVI Pro interface. These can be gathered
through the Extended I/O connector. See Connecting an External Sensor to an
MPVI Pro (Page 73).
￭ External analog inputs connected to an MPVI2 via an attached Pro Link cable or an
MPVI2+ or MPVI3 via an attached Pro Link+ cable. Your interface device must have a
license for the Pro Feature Set. See Adding Pro Link and Pro Link+ Analog Inputs
(Page 76).
￭ A 500 kbps CAN bus input can be connected via a Pro Link or Pro Link+ cable. Your
interface device must have a license for the Pro Feature Set. See Adding Pro Link
and Pro Link+ CAN Bus Inputs (Page 79).
￭ Third party devices that can be connected to the computer's serial port (or a
USB port with a serial to USB adapter). See Devices That Connect to a Serial Port
(Page 81).

CHANNELS
ADDING OBD PORT CHANNELS

1. Connect to the vehicle you wish to define channels for (but do not start scanning).
NOTE: If you have connected to this vehicle before, VCM Scanner will have
created a vehicle profile for it. Selecting this profile allows you to add
channels for the vehicle when you are not connected.
2. If the Channels list is not already open, click the tab on the left edge of the screen
to display it.
3. Click the icon in the Channels list. The Channel Selector window appears.
4. Browse or search for the channel you wish to add. Channels received through the
OBD-II port are at the top of the list (all groups except External Inputs).
Keep the following in mind when selecting a channel:
￭ Channels whose names have a BLUE background have already been added.

￭ If the icon to the left of the channel name has a GREEN background, it is a
broadcast channel. These channels are preferred because adding them will not
slow down the retrieval of scanned data.
5. Double-click on the channel you wish to add. The channel should now appear in
the Channels list.
6. If the channel is a polled parameter that you do not need frequent updates for
(perhaps because the measured value changes slowly), consider reducing the
polling frequency to reduce the overall burden on the system. To do this, right
click on the polled channel and the select Polling Interval.
HP Tuners, LLC
7. If desired, you can adjust the units for the new channel or the number of decimal
places displayed for it by right clicking on the channel and selecting the cor-
responding menu item.
SCANNER PERFORMANCE OF POLLED PARAMETERS

Polled parameters are parameters that VCM Scanner must ask the vehicle controller
to provide. Each one of these you add, creates additional processing burden on the
system and may slow down the rate at which data is reported to you.
￭ In the Channel Selector window, the icons associated with polled channels have a
WHITE background (not a GREEN one).
￭ Once a polled parameter has been added, the icon will appear next to it in the
Channels list.
Broadcast parameters do not suffer from this drawback. These are parameters that
the vehicle is always sending and require no additional overhead in collecting. Given
the choice between a Polling and a Broadcast parameter, you should chose the
Broadcast one. However, not all vehicles support broadcast channels.
Channels based on external inputs (Pro Link, Serial Port, etc...) also do not affect the
rate at which parameters are gathered from the vehicle.
IMPROVING PERFORMANCE OF POLLED CHANNELS

To improve performance, lower the interval on polled channels that do not require
great resolution. For example, setting Engine Coolant Temperature to 10 seconds
might be more appropriate than .1 seconds. This frees up bandwidth space for a
parameter that might require higher resolution, like Spark Advance.
To do this, right click on the polled channel in the Channel display and the select
Polling Intervals.

DEVICES THAT CONNECT TO A SERIAL PORT

VCM Scanner includes support for external sensors that connect directly to a
computer's RS-232 serial port.
Years ago, most laptops included such a port. But, the majority of laptops built today
no longer have them. If your laptop does not have a built in serial port, you will need a
USB to serial port adapter such as: TRENDnet TU-S9 USB to Serial Converter.
NOTE: Support is limited to specific external sensors that are predefined in the
software. If your device has a serial output and you'd like us to add VCM Scanner
support for it, please contact us.
BEFORE YOU BEGIN

It is important that your computer has the most recent serial port drivers and drivers
for the USB to serial port adapter. Be sure that it has the latest updates installed.
CONNECTING A SENSOR
1. If your computer does not have a serial port that fits the cable from the device,
connect the USB to Serial Port adapter to your PC.
2. Connect your sensor's serial output to the Serial Port connector on your PC or
USB adapter.

4. If the Channels display is not already open, click the tab on the left edge of the
screen to display it.
5. Click the icon in the Channels display. The Channel Selector window appears.

TRANSFORMING A CHANNEL
Most scalars that come from external inputs can be transformed into other values.
This can be useful for:
￭ Transforming the voltage of an analog signal into Equivalence Ratio, Air/Fuel Ratio,
Temperature, Pressure, etc.
￭ Transforming a Serial input Equivalence Ratio into an Air/Fuel ratio
￭ Transforming a raw external input value into a parameter value
BRINGING UP THE TRANSFORM MENU

On the Channel display, you can right click a channel to bring up the menu. If the
channel supports transformation, you will see an option called "Transform".
HP Tuners, LLC
CHANNELS
SELECTING YOUR TRANSFORM

The Transform Selector form will show you any transforms that apply to the channel
you have selected.
For example, if your base channel is a voltage input, the Transform Selector will show
you transforms that take voltage as the input.
If your transform is not listed in the Transform Selector window, and you would like us
to add it, please contact our customer support department and we can look into
adding it to a future build.
Alternately, you can define your own transform. See Defining Your Own Transform
(Page 90).
HP Tuners, LLC
DEFINING YOUR OWN TRANSFORM

If your sensor is not listed in the Transform Selector window, or you must account for
a signal/noise offset, you can define your own transform.
1. In the Transform Selector window, select a sensor that is similar to the sensor you
wish to add.
2. Click the button to copy the selected sensor's parameters into the fields at the
bottom of the window. (This should give you a starting point close to the sensor
you want to add.)
3. Click the Parameter link. The Parameter Selector window appears.

4. Double-click on the parameter that you wish map your sensor output to.
NOTE: The transform will convert the input source into an output of the type
of the parameter you selected. When adding channels that use this transform
to your layout displays, you simply add the parameter you specified here.
5. In the dropdown to the right of the Parameter link, select the units for the output
parameter.
6. Use the Function fields to specify how the range of values output by the
connected sensor should be transformed into the range of values for the selected
parameter. See Defining the Function (Page 91) for more information.
7. Enter a Description for this transform.
8. Click OK.
HP Tuners, LLC
CHANNELS
The user transform values you input will be stored with the channel, and will be saved
any time you save your channel config.
DEFINING THE FUNCTION

The Function fields define how the numerical values associated with the input are
converted to their corresponding output values. In the sample screen above, the
function is converting values in the range 0-5 (volts) to values in the range 0.62-1.10
(Lambda).
To define the function, you just need two known input values and their corresponding
output values. Consult the documentation for the device whose output you are trans-
forming.
Once you have these values, the number to put in the first box can be calculated with
the following formula:
(Input2 - Input1) / (Output2 - Output1)
If we used the max and min values from the example above, you would get:
(5 - 0 volts) / (1.10 - 0.62 lambda) = 10.41666
To determine the value of the second box, you simply plug either of the two known
input and output pairs into the resulting equation and solve for the missing value.
In our example, if you insert the 0 volt input and it corresponding output value, you
get:
0/10.4166 + X = 0.62.
So, X = 0.62.

LOADING AND SAVING THE CHANNEL

CONFIGURATION
It is recommended that you save separate channel configs for common tasks and
vehicles.
However, you do not need to save your channel configuration every time you make a
change. VCM Scanner will remember all the changes you make and reload them next
time you open VCM Scanner.
SAVING THE CURRENT CHANNEL CONFIGURATION

To save the current channel configuration:
1. Click the icon at the top of the Channels list.
2. Enter a file name and click Save.
Channel configurations are saved as xml and include the following information:
￭ Parameter ID
￭ Parameter Source
￭ Polling Interval
￭ Any Transform (if applied)
LOADING A SAVED CONFIGURATION

To load a channel configuration that you have saved to a file:
2. Select Open Channel Config.

3. Browse for and select a saved channel config file.
4. Click Open.

LOADING THE DEFAULT CHANNEL CONFIGURATION

You can load two different default channel configurations for the current vehicle.
1. Either connect to the vehicle for which you wish to load defaults or select its
vehicle profile.
3. Select one of the two options described below.
LOAD SAE DEFAULTS

This will load a default set of supported SAE parameters for the current vehicle. These
will only provide a basic set of parameters.
LOAD VEHICLE DEFAULTS

This will load a default set of supported manufacturer specific and SAE parameters for
the current vehicle. This will provide the best starting point for most vehicles.
HP Tuners, LLC
ADVANCED CHANNEL PROPERTIES

Each controller OS supports its own unique parameters. When you connect to a
vehicle, VCM Scanner will attempt to identify the OS used by each of the vehicle's
controllers so that it can then load appropriate parameter definitions.
The Channel Config Advanced Properties window allows you to specify "fallback" and
"override" OS IDs in order to tell VCM Scanner what parameter definitions it should
load in certain situations.
To open this window, right-click on the Channels display and select Channel Config
Advanced Properties.
NOTE: These settings will persist when you connect to different vehicles. Using
these settings may limit or break functionality when connecting to different
vehicles.
HP Tuners, LLC
CHANNELS
OS FALLBACK
If an OS Fallback is specified for a controller, VCM Scanner will use the fallback in the
following situations:
￭ The vehicle doesn't report its OS ID and there is no user-defined OS ID specified in
the vehicle profile.
￭ Th vehicle reports its OS ID or there is a user-defined OS ID specified in the vehicle
profile, but VCM Scanner can't find parameter definitions for the OS ID indicated.
NOTE: Vehicle profiles and fallback properties are the preferred methods for
helping VCM Scanner load parameter definitions. OS Overrides are a far more
extreme solution.
OS OVERRIDE
If an OS Override is specified for a controller, VCM Scanner will always load the
parameter definitions for the specified OS for all vehicles.
￭ The OS ID reported by the vehicle (if any) will always be ignored.

￭ User-specified OS IDs specified in the vehicle profile (if any) will also be ignored.
CAUTION: Take care when using these as it will severely limit the trans-
portability of your channel configuration. This may also severely limit VCM
Scanner capabilities when you connect to different vehicles.
When an override is set, you will see an indication that says Definition Overrides Set:
HP Tuners, LLC
MPVI INPUTS AND OUTPUTS

The standard MPVI interface supports defining channels based on parameters
received through the vehicle's OBD-II port.
If you have an MPVI Pro interface, the Enhanced IO interface can be used to attach up
to four devices that generate an analog output. See Connecting an External Sensor to
an MPVI Pro (Page 73) for details.
NOTE: The EIO interface also includes two outputs (pins 7 and 8) that were
designed to control external devices such as LEDs and relays. However, this
function is no longer supported by VCM Scanner.
HP Tuners, LLC
CHANNELS
MPVI2, MPVI2+, AND MPVI3 INPUTS

In addition to channels based on parameters received through the vehicle's OBD-II
port, these input devices allow you to create channels for the following data sources:
￭ External analog inputs connected to an MPVI2 via an attached Pro Link cable or an
MPVI2+ or MPVI3 via an attached Pro Link+ cable. Your interface device must have a
license for the Pro Feature Set. See Adding Pro Link and Pro Link+ Analog Inputs
(Page 76).
￭ A 500 kbps CAN bus input can be connected via a Pro Link or Pro Link+ cable. Your
interface device must have a license for the Pro Feature Set. See Adding Pro Link

EXPRESSION FILTERING
Entering an expression in the Function field of the Graph Display Layout Editor sets a
condition which must be met for the data to be included in the graph you are
configuring.
NOTE: Expression filtering, does increase processing overhead, and may not
perform well on slower devices.
Defining the function for a filter follows the same procedure as the expressions for
math parameters:
1. Insert variables that represent that output of the sensors and/or PIDs that will be
included in the calculation.
2. Add supported math operations to complete the desired calculation.
The completed function must evaluate to TRUE or FALSE (1 or 0). Each frame of data
received will be checked against this function:
￭ If the function evaluates as TRUE (1) for the frame, the data in the frame will be
added to the graph.
￭ If the function evaluates as FALSE (0), the data from the frame will NOT be added to
the graph.
EXAMPLE
Suppose we want to create a filter that filters out throttle values < or = to 50% as well
as the transitions before and after. To accomplish this, we need a filter expression
that will return TRUE if ALL of the following conditions are true:
￭ Throttle % > 50
￭ Throttle % has been > 50 for 500 milliseconds
￭ Throttle % will be > 50 for 500 milliseconds
Part 1 - Throttle % > 50
1. Click New Variable. The Variable Wizard appears.
HP Tuners, LLC
HP Tuners, LLC
LAYOUTS
3. Search for throttle position and select (double-click on) the Throttle Position
sensor in the Generic Sensors group.
4. In the Unit dropdown of the Variable Wizard window, select %.
5. Click OK. The filter expression should now show a text representation of the
Throttle % variable you just created:
[50090.156]
6. For this first part of our expression, we simply need to make sure Throttle % is >
50. So, we just need to add > 50 after our throttle position variable:
[50090.156] > 50
Part 2 - Throttle % has been > 50 for 500 milliseconds
Now, we need to filter out the transitions before this period. To do that, we can use
the average function to verify that the average throttle % has been over 50 for at least
500 ms.
1. This second condition has to ALSO be true. So, we add AND to our expression.
[50090.156] > 50 AND
2. Click New Variable to open the Variable Wizard again.

3. Select the same Parameter and Unit that was selected in Part 1.
4. In the Special Function box, select Average and enter a Period of 500 ms.
HP Tuners, LLC
5. Click OK. Our expression should now look like this:
[50090.156] > 50 AND [50090.156.avg(500)]
6. For this period, the throttle position needs to be over 50%. So, we add > 50 to this
part of the expression as well:
[50090.156] > 50 AND [50090.156.avg(500)] > 50.
Part 3 - Throttle % has been > 50 for 500 milliseconds
Now, we need to filter out the transitions after this period. This requires exactly the
same procedure that we used for Part 2. However, we will use -500 ms for the period.
NOTE: Using a negative value for the Period tells VCM Scanner to look at the
period AFTER the current time index. This works only during playback of recorded
data streams. When Iive scanning, VCM Scanner can't obtain the specified
information (it can't look into the future).
So, we add the following to the end of our expression:
AND [50090.156.avg(-500)] > 50
So, the final expression would look like the following:
([50090.156] > 50) AND ([ 50090.156.avg(500)] > 50) AND ([50090.156.avg(-500)] >
50)
NOTE: We've added parentheses to make the expression more readable. But, this
is optional. The expression will work without them.

DRIVE CYCLE PANEL
Drive cycles are standardized driving patterns used for testing emissions and fuel
economy. The Drive Cycle panel provides guidance for the driver when attempting to
perform one of these tests. Performing a standardized drive cycle can be useful when:
￭ Ensuring that emissions and fuel economy testing of your build complies with
national and/or local regulation.
￭ If you have recently cleared DTCs, disconnected the vehicle battery, or performed
other major maintenance, the on board emissions monitors will reset and may
take several drive cycles to complete their testing. Vehicles will not pass emissions
testing until these on board tests are completed. Following a standardized driving
cycle helps to ensure that this testing is completed as quickly as possible.
HP Tuners, LLC
PERFORMING A DRIVE CYCLE

Completing a drive cycle requires that the driver accelerate to specific speeds (or
above) and then maintain those speeds for several minutes. Typically, the driver will
then be required to decelerate or stop and then accelerate to a specified speed
multiple times.
It is recommended that you begin the test with a relatively cold engine and proceed
immediately to an open highway with little to no traffic so that you can accelerate and
decelerate without worrying about surrounding vehicles.
1. Connect your HP Tuners interface device to your laptop and then connect the
interface to the OBD-II port on the vehicle to be tested. See Connecting to a
Vehicle (Page 23) for details.

4. Open a layout that includes a Drive Cycle panel.
5. In the Drive Cycle Test dropdown, select the test that you wish to complete.
6. Turn the vehicle ignition ON.
8. When the vehicle is in position to begin the test, click to start scanning.
9. The white line on the Drive Cycle panel will indicate a target speed. Accelerate to
the target speed. The green line will indicate the current speed of your vehicle.
10. Continue following the white line for guidance until the drive has been completed.
NOTE: After the drive cycle, you can check to see if the vehicle's emissions
monitors have completed their self testing in the Diagnostics & Information
window. See Checking Emissions Monitor Status (Page 32) for details.

SELECTING A PARAMETER
Parameters are sensor outputs or other signals that may be useful to monitor using
VCM Scanner. You will need to select a parameter when you do any of the following:
￭ Add a signal to the Chart vs. Time panel.

￭ Add a gauge to the Gauge panel.
￭ Add a table or histogram to the Graph panel (tables require selecting three
parameters: cell content, column axis, and row axis).
￭ Define a Math Parameter or an Expression Filter. The calculations performed by
these structures often include multiple parameters.
However, the parameter will not provide data during scanning or playback unless a
channel has been defined to supply data to it. For example, if your chart, gauge, table,
or math parameter is tied to "Engine Speed", you must have an "Engine Speed" channel
in the channel list. See Channels (Page 65) for more information.
PARAMETER GROUPS
SPECIFIC PARAMETERS
Specific parameters are tied to a specific channel provided by the vehicle's control
modules.
Since the channels that are provided vary from vehicle to vehicle, gauges, graphs, etc.
that use parameters in this group are often not portable to vehicles with different
controllers and operating systems than the original vehicle.

GENERIC SENSORS
The parameters in this group will work with any channel that provides the type of

portability from vehicle to vehicle.
EXTERNAL INPUTS
This group lists external inputs that can be connected to your computer either
through your HP Tuners interface device or though your computer's serial port.
The parameters listed here represent the raw, untransformed data from the external
input. If you applied a transform to this input in the channel list, select the transform
you used from the Transforms group to use the transformed data instead.
TRANSFORMS
Lists transforms that can be applied to external channels. If you added a channel that
required a transform, select the transform that was applied to the channel to use the
transformed output.
NOTE: If there is a generic sensor of the same type, VCM Scanner will prompt you
to see if you want to use the generic sensor instead.
MATHS
This group contains parameters that are defined by performing calculations on the
output of one or more other parameters. There are a number of pre-defined math
parameters based on commonly-used calculations. But, it's also possible to create
custom math parameters of your own. See Math Parameters (Page 157) for more

DEFINING EXPRESSIONS
An expression is the mathematical formula that is used to calculate the parameter's
value. The expression can include the output of sensors and PIDs, which are inserted
into the expression as variables.
The process for defining an expression is as follows:
1. Insert variables that represent that output of the sensors and/or PIDs that will be
included in the calculation.
2. Add supported math operations to complete the desired calculation.
Note that there are two types of expression:
￭ Calculated
￭ Conditional
HP Tuners, LLC
CALCULATED EXPRESSIONS
A calculated expression applies mathematical operations to the output of the sensors
or PIDs identified in the expression in order to provide a modified signal or a signal
that is derived from multiple inputs.
Examples:
￭ 100 * ([50119.238] - [50118.238]) / [50118.238]

￭ ([2126.240] * ([6210.71] / 1000) * [50112.254] * [50121]) / [50030.91]
CONDITIONAL EXPRESSIONS
A conditional expression specifies a function that tests the output data stream of the
sensors or PIDs identified in the expression and produces a TRUE or FALSE result for
each frame of the output.
This type of expression is typically used in filters.
Conditional expressions must return either 1 (TRUE) or 0 (FALSE).
Examples:
￭ [50010] > 25
￭ ([50010] > 25 OR [25] = 50) AND [3131] > 10
HP Tuners, LLC
MATH PARAMETERS
EXPRESSION VARIABLES
When entering expressions for math parameters or filters, variables are used to
represent the output of a particular sensor or PID. There are two ways to add a
variable to an expression:
￭ Type the variable specification directly into the Expression box as text.
￭ (Easier) Click the New Variable button to open the Variable Wizard.
ENTERING VARIABLES AS TEXT

The basic syntax for a variable is simply the master Parameter ID for the sensor or PID
surrounded by square brackets.
For example, a variable that inserts the output of the throttle position sensor would
be written as follows:
[50090]
SPECIFYING UNITS
There are two ways to specify the units for a variable:
￭ Give the numerical Unit ID. This is the preferred method.

￭ Enter the symbol for the unit. This is not as reliable.
Both of these examples specify mph as the unit:
￭ [12345.114]
￭ [12345.mph]
Supported symbols and IDs are listed in the Quantities & Units window.
HP Tuners, LLC
VARIABLE MODIFIERS (CASE INSENSITIVE)
avg(x) Calculates the average value of the variable over the period
that:
￭ begins x milliseconds before the current time index
￭ ends at the current time index
slope(x) This will calculate the slope between two points:

￭ the value of the variable at x milliseconds before the
current time index
￭ the value of the variable at the current time index
shift(x) The value of the variable x milliseconds before the current

time index.
NOTE: Using a negative value for x tells VCM Scanner to look at the period AFTER
the current time index. This works only during playback of recorded data streams.
When Iive scanning, VCM Scanner can't obtain the specified information (it can't
look into the future).
VARIABLE EXAMPLES (CASE INSENSITIVE)

MATH PARAMETERS
VIEWING MATH PARAMETER VARIABLE BREAKDOWN

When either a Predefined or a User Defined math parameter is selected, the box in
the bottom right of the Math Parameters Manager window will display simple descrip-
tions of the variables used in the selected math parameter.
Variables that are highlighted in pink are not currently supported by the active
channel configuration.
HP Tuners, LLC
SHARING USER DEFINED MATH PARAMETERS

If your user defined math parameter is generic enough that you think others might
use it, please e-mail it to us and we can add it to our Predefined list.
User math parameters are stored in the local computers "VCM Scanner.cfg" file. They
are not distributed with any Channel or Layout configuration. If you build a layout that
includes user defined math parameters, anyone you share it with will not be able to
display those controls unless you also share the math parameter and the recipient
loads the math parameter into the same slot as you.

REAL TIME TUNING (RTT™)
REAL TIME TUNING

(RTT™)
HP Tuners, LLC
RTT™ is an operating system modification available for certain vehicles with LS1
engines. This mod allows users to change the values of certain parameters in real time
while connected to the vehicle in VCM Scanner.
NOTE: To do this, the customized operating system copies parameters that are
normally stored on the controller's internal flash drive into the controllers RAM
memory. The parameters in RAM can then be modified in real time, without
flashing the vehicle.
After tuning is complete, the final parameters can be written to the PCM and stored
permanently using VCM Editor.
FEATURES
￭ Software only, no special hardware required
￭ Enough functionality to tune the car. (Not every parameter requires real time
support.
￭ Easy to use
￭ Low cost
CAUTION: Do NOT attempt changing real time tune values while driving the
vehicle. Doing so may cause driver distraction and possible vehicle crash.
Real time tuning is designed for quick tuning under controlled conditions like
an engine or chassis dynamometer.
CAUTION: Use caution when entering values into the real time tuning tables.
Improper use may cause vehicle damage and or unsafe driving conditions.
The user assumes all safety responsibility for use of and values entered into
real time tuning mode.
HP Tuners, LLC
PROCEDURE
1. In VCM Editor, open a calibration file read from a vehicle that supports the RTT
operating system modifications. See Operating System Enhancements with RTT
(Page 174) for a list of these mods and the vehicles they can be applied to.
2. Apply an HP Tuners OS modification that includes RTT capabilities. See Applying a

Custom OS with RTT (Page 177) for instructions.
3. Select the RTT Mode and write the new calibration to the vehicle. See Selecting the
RTT™ Mode (Page 181).
5. Click to establish a data connection. The RTT icon will appear in the toolbar.
6. Click the RTT icon to open the Real Time Tuning window. See The Real Time
Tuning Window (Page 182) for more information on using this window.
NOTE: This icon will not be displayed unless you have flashed a tune to the
vehicle with RTT Mode set to anything other than Disabled.
7. For each table you wish to modify:
a. Use the number buttons at the top of the window to select the table you want
to modify. Intially, the table will appear blank because its data has not yet been
copied from the flash drive.
b. Click to copy the selected table to the controller's RAM memory and tell
the controller to use the copy in memory rather than the original on its
internal flash drive.
c. Edit the table as desired. Your changes will take effect in real time.
HP Tuners, LLC
d. When you have built a table that you feel is worthy of applying to the vehicle
permanently, right click on the table and select Copy.
e. In VCM Scanner's toolbar, click to disconnect.
f. Open VCM Editor and navigate to the tab containing the table that you are
finalizing.
g. Right-click on the colored background of the table's name and select Paste.
8. When you are ready to write a batch of changes to the vehicle's flash drive,
perform a calibration only write to the vehicle.
NOTE: You do not have to disable the RTT™ mode in VCM Editor to write changes.
You can leave the mode set to a desired RTT mode and continue real time tuning
your vehicle as needed.
OPERATING SYSTEM ENHANCEMENTS WITH RTT

VCM Suite can apply operating system enhancements that add RTT to many vehicles
that have an LS1 engine from GM. If your vehicle supports these enhancements, you
will see them listed on the OS tab in VCM Editor.
Details for these custom operating systems are included below. See Applying a
Custom OS with RTT (Page 177) for instructions on applying any of these custom
operating systems to your vehicle.
HP Tuners, LLC

￭ Speed density mode only
￭ VCM Scanner histogram automatically recognizes and adjusts for 2 bar feature (if
applicable)
￭ New 3 bar MAP PID for VCM Scanner (if applicable)
NOTE: You must use a correctly calibrated 3bar MAP sensor for this application.
The default MAP sensor calibration values may not be accurate for your MAP
sensor.
APPLYING A CUSTOM OS WITH RTT

Applying custom OS that includes RTT is similar to applying any other OS mod.
If you already have an existing VCM Enhancement applied to your vehicle and wish to
use RTT, you will need to re-apply the VCM Enhancement with RTT from your stock GM
OS.
CAUTION: Use these enhancements at your own risk. Modifications can result
in permanent damage to vehicle components. Any modifications that change
the vehicle's emissions from stock (most modifications do this) are not
allowed by the EPA and are to be used for off-road applications only.
Modifying or removing any emissions testing is illegal and subject to heavy
fines. HP Tuners LLC is not liable for any type of damage caused by use of
these enhancements. Use at your own risk!
HP Tuners, LLC
To apply the enhancement to your PCM:
1. In VCM Editor, open the stock or existing tune read from the vehicle.
2. Select the OS tab. Enhancements that are available for the PCM's operating system
will be listed under Code Modifications.
3. Apply the relevant modification by clicking the button.

4. Immediately save the file under a new name. DO NOT make any additional
changes before saving the file. This is now your new "Base" file that must be used
for all future tuning.
5. Close VCM Editor and then reopen it with the newly saved file. You should see that
the operating system ID for the vehicle's PCM has changed from your original file.
HP Tuners, LLC
6. For 2bar and 3bar enhancements only: The VE table will be full of invalid data.
You *must* create a valid VE table before writing the file to the PCM.
NOTE: One strategy is to copy your previous VE table into the non-boost
region and then copy and increase the last row of the VE table to the new
boost area. It is important to start tuning on the rich side (higher numbers)
and then work back to your desired AFR.
7. Save the file in the editor, you are now ready to write to the PCM.
IMPORTANT: The next step involves using the "Write Entire" option. Remember
this option is not 100% recoverable on failure in some circumstances. Do NOT
disconnect the battery if you have problems during this next step. Once this
step is completed, you can use the normal "calibration only" write function for
all tuning changes.
8. Connect to the vehicle and turn on ignition, wait 10 secs.

9. Still in VCM Editor with your file open, select Flash > Write Entire. The process
takes approximately 2-4 minutes depending on vehicle type.
10. When the write is completed, turn off ignition and wait 30 secs.
11. Turn on ignition, wait 10 secs.
12. The PCM should display the new operating system ID.
13. At this point the PCM should now be running the new operating system and you
can now use (much safer) calibration only writes for all future tuning changes.
HP Tuners, LLC
14. For 2bar and 3bar enhancements only, remove the 1bar SAE Manifold Air Pressure
PID and replace it with the appropriate 2 or 3 bar PID:
a. Open VCM Scanner and connect to the vehicle.
b. In the Channels list, right-click the Manifold Air Pressure (SAE) PID select
Remove Channel.
c. Right-click in the Channels list and select Add Channel.
d. Go to the Engine > Airflow folder.
e. Choose either the Manifold Air Pressure - 2 bar or Manifold Air Pressure - 3
bar PID. Double-click to insert it into the table.
NOTE: If you don't do this, layouts that use MAP parameters will not function
correctly.
15. For 1/2/3 bar Speed Density enhancements only:
￭ Right-click the Mass Air Flow(SAE) PID and select Remove Channel.
NOTE: This removes the existing MAF PID. If you don't do this, layouts that use
MAF parameters will not function correctly.
16. If you made any changes to the channel configuration in step 14 and/or step 15,
click to save your changes.
You are now ready to select the RTT mode.
HP Tuners, LLC
SELECTING THE RTT™ MODE

Due to the limited amount of space in the vehicle control module's memory, it can
only maintain a few tables in RAM at one time.
VCM Suite gets around this obstacle by giving you modes of operation to choose from.
Each mode loads a set of tables that allows you to accomplish one major task, like idle
or VE tuning.
To select the RTT mode you wish to use:
1. In VCM Editor, open the tune file to which you applied the RTT OS Mod.
2. In either the tab navigation interface or Parameter Navigator, select Engine >
General.
3. Use the Real Time Mode dropdown to select the mode you want.
NOTE: The modes are named for the tuning task they are meant to be used
for.
4. Write the calibration to the vehicle (write calibration only).
NOTE: If you do not select a mode other than Disabled, the RTT icon will not be
displayed in VCM Scanner's toolbar.
HP Tuners, LLC
THE REAL TIME TUNING WINDOW

If you have selected an RTT Mode other than Disabled in VCM Editor and then written
the tune to the vehicle, the RTT icon will appear in VCM Scanner's toolbar when you
connect to the vehicle.
Click this icon to bring up the Real Time Tuning window.
This window is similar to the Table Editor in VCM Editor and includes many of the
toolbar icons and the right click menu from that window. See the Table Editor section
in the VCM Editor User Guide for more information on these functions.
HP Tuners, LLC
ADDITIONAL TOOLBAR ICONS

This window includes a few additional toolbar icons that are not present in the VCM
Editor.
Select Table: Each of these numbers represent a table that is available for
real time tuning in the current mode. Click a number to select the cor-
responding table.
By default, the controller will use the versions of these tables that are stored
on its flash drive.
Use RAM Version: Intstruct the controller to use the version of the selected
table in RAM. This allows the table to be modified in real time.
Use Flash Version: Instruct the controller to user the version of the table on
the flash drive. This table cannot be modified in real time.
Use Flash Version for All: Instruct the controller to switch to the flash
versions of all tables.
COPYING A TABLE TO RAM AND MAKING IT ACTIVE

When you are ready to start tuning a table in real time:
1. Select the table by clicking the number corresponding to the table you want to
modify. Initially, the table will appear blank because its data has not yet been
retrieved from the flash drive.
2. Click . This will tell the vehicle controller to copy the table into RAM memory
and start using that copy rather than the original table on its internal flash drive.
HP Tuners, LLC
USING THE FLASH TABLE AGAIN

If you have built a table in RAM that you do not wish the vehicle to use anymore,
simply click . This will tell the vehicle to use the table that is located on the flash
drive and not the one RAM.
NOTE: This will not remove your changes to the table in RAM. If you click the Use
RAM Version icon again, you can continue tuning the table where you left off. Your
changes will not have been lost.
If you want to erase the tables in RAM, simply key off or cycle the ignition. Any changes
made to the table in RAM will be lost and refreshed with table data from the flash
drive.
