Configuring Start Triggers (Optional)

By default, a short press of the BT button will start logging. You can also set triggers based on the vehicle’s acceleration.

1. In the menu, select Vehicle > MPVI2 Data Logging and go to the Start/Stop Triggers tab.
   
2. If desired, select Street Car or Race Car for preset values in the Sustained Acceleration fields.
3. Configure fields in the Start Trigger group:
   • Short Button Press: Starts logging with a short BT button press (when enabled).
   • Instantaneous Acceleration: Starts logging when the specified acceleration is reached.
   • Sustained Acceleration:Starts logging when the specified acceleration is sustained for a set duration (e.g., 0.05 G for 1 second).

     Note: Avoid using accelerometer triggers with OBD extension cables as movement may impact accuracy.

4. When done, click Set Triggers.

Configuring Stop Triggers (Optional)

By default, a short press of the BT button will stop logging. You can also configure triggers based on RPM or acceleration.

1. In the menu, select Vehicle > MPVI2 Data Logging and go to the Start/Stop Triggers tab.
    
2. Choose Street Car or Race Car for suggested RPM values.
3. Configure fields in the OR Trigger Group or AND Trigger Group:
   • Short Button Press: Stops logging with a short BT button press (when enabled).
   • Sustained Acceleration: Stops logging when acceleration drops below the specified value for a set duration.
   • RPM: Stops logging when RPM falls below a specified value for a set time.
4. Click Set Triggers to save.

   Note: Logging also stops if there is no movement and zero RPM for one minute.

Generating a Log

• Disconnect the device from your computer, ensuring it’s not connected via Bluetooth® to any app.

• Wait up to two minutes for the device to be ready for logging (or unplug and reconnect it to the OBD-II port for a quicker reset).

• Connect the device to the vehicle’s OBD-II port.

• Start the engine or set the vehicle to ON/RUN without starting the engine. Logging should begin 5-10 seconds after the trigger is met (the amber OBD light will flash).
  
  Note: Logging stops automatically when the stop triggers are met. To stop manually, press the BT button.

  Caution: Always use the stop button before unplugging the device to prevent data loss.

  Note: For first-time logging on a new vehicle, allow an additional 5 seconds for initiation.

Notes

• Avoid connecting to VCM Suite, TDN, or TrackAddict during logging, as this will stop the process. Data logged up to that point will be saved.
• If data logging fails to start (e.g., ignition off), it will reset and wait for a new trigger.
• During startup, the OBD and Host lights may flash intermittently—this is normal.

Retrieving Log Files

1. Open VCM Scanner.
2. Connect the interface device to your computer.
3. Select Vehicle > MPVI2 Data Logging and go to the Log Files tab. Recent logs appear at the top and are named with a sequence number and VIN.

   Note: MPVI2 lacks a persistent clock, so dates will default to 1980 unless connected to VCM Suite, TDN, or TrackAddict in the same power cycle.

4. Select the desired log file and click Read Selected.
    
5. Choose a destination folder to save the file.

  5. Reset channel configuration by clicking Erase Channels Config and try again.

• Standalone Data Logging is Not Stopping:

  1. Check that Short Button Press is enabled under Start Triggers.
  2. Reset the channel configuration by clicking Erase Channels Config.

• Blank Channel Values or Errors:

  1. Ensure the ignition is on or the engine is running during logging.
