Just when you go to reprogram a new, unlicensed (at least on your FlashScan unit) controller. You can data log and read tunes from unlimited supported vehicles for free.

2004gmc,

Welcome to the forum...:cheers:

Exactly what Erik said, a license is used up only when flashing a PCM/ECM/TCM for the first time.

The license attaches to the controller... 1 license attaches to 1 PCM or to an ECM/TCM pair.

The 1997/1998 LS1 Y-car/F-car PCM's are free, no license required for flashing those.

Reading the flash and scanning/logging does not use any licenses.
