Note: This feature is available for late-model GM vehicles only.

Setup

To set up standalone data logging for the first time on a new vehicle or when switching vehicles:

• Turn the vehicle’s ignition to ON/RUN.
• Connect the MPVI Pro to the vehicle’s OBD-II port and to your laptop’s USB port.
• Open VCM Scanner.
• Click the Connect  icon in the toolbar.
• Ensure the channels you wish to log are listed in the Channel display (add or delete channels as needed).
• (Optional) Click Save Channel Config to save your channel configuration.
• In the menu, select Vehicle > MPVI Pro Data Logging. The MPVI Pro Standalone Data Logging Functions window will open.
  
  
• Click Write Config to write the current channel configuration to the MPVI Pro.

  Note: Writing a new configuration will erase any logs currently stored on the device.

• Disconnect the MPVI Pro’s USB cable from your laptop.

Generating a Log

The MPVI Pro can store up to 32 individual logs or approximately 80 minutes of data. Actual capacity may vary based on the vehicle and the data recording rate.

1. Start the vehicle (if it isn’t already running).
2. To start recording, press and hold the Record button on the MPVI Pro for 2 seconds.
3. To stop recording, press and hold the Stop button for 2 seconds.

   Caution: Always use the stop button to end logging. Powering down the unit while recording or while the Busy LED is lit may corrupt the log.

Inserting a Marker

To insert a marker during recording:

• Press the Record button for 1 second. The Busy light will blink, indicating that a marker has been added.

  Note: There is a 2-second delay before you can add another marker.

Additional Notes

• All button presses take 1 second to validate.
• The Record light blinks when 90% of the memory is used (about 6 minutes of space remaining).
• The ERR light flashes if the interface fails to establish communication with the vehicle.
• The ERR light remains solid if no configuration is loaded, if the interface memory is full, or if a corrupt log location is detected.

Getting Info from the Device

To view stored information, click Get Info in the MPVI Pro Standalone Data Logging Functions window. This displays:

Retrieving Log Files from the Device

1. Connect the MPVI Pro to your computer.
2. In VCM Scanner, go to Vehicle > MPVI Pro Data Logging to open the MPVI Pro Standalone Data Logging Functions window.

• Retrieve a specific log:
  1. Click Get Info to display available logs.
  2. Select the log you want from the left column.
  3. Click Read Selected.

     Note: Retrieving logs does not erase them from the device.

Erasing Logs from the Device

To erase all stored logs, hold the Record and Stop buttons on the MPVI Pro for 2 seconds. The Busy LED will blink until the logs are deleted.

1. Connect the MPVI Pro to your computer.
