PCMTec Editon Required: One Car Workshop or Workshop.

Tuner Lock is a widely debated feature however for many tuners it is a must. Tuner Lock is a soft lock that will prevent other PCMTec users from editing/viewing/datalogging your tune. This includes other competitors' products as well.

Tuner lock will prevent everyone including yourself from datalogging the vehicle and it will also prevent you from using the CustomOS Wizard. Hence it is recommended to only turn this feature on before it leaves the workshop. There is no cost to use Tuner Lock.

To enable tuner lock, press "Calibration Tools" -> "Binary Tuner Locked (OSID Scramble) Active".

Press "Yes" to save the file and the file will now be tuner locked.

You can confirm by checking the “Binary Tuner Locked (OSID Scramble) Active". You should see there is a "✓" on the left-hand side.

Or you can check here, "Custom Operating System Build Options" -> "Tuner Lock Enable/Disable".

Now if any other users read this file they will be greeted with the following popup.

If you would like to turn off the Tuner Lock feature (given it's your own tune), just simply open the tuner-locked file and because you are the tuner who locks the tune, you will be able to view the file with a full list of the parameters.

Then press "Calibration Tools" -> "Binary Tuner Locked (OSID Scramble) Active".

Press "Yes" on the pop-up.

The file now is unlocked.
