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.
2. Connect to the vehicle and perform a live scan. See Scanning Procedure
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.

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.
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.
