Need help, LS1B controller I have had licensed for years now suddenly wont let me flash to it due to no license?
I used the controller to show a buddy how to program a pcm using my Tech II in pass-through mode and unintentionally did flash the pcm due to me not paying full attention. This changed the OS and VIN, so I took out my V2 and reloaded my OS and tune file via a full flash in V8. Now it will not let me flash at all saying I need to buy a license?? HELP! I have more work to do to this file!

Th controller serial number is not changeable is it??

I did run an update on V7.5 after the full flash in V8.

TIA,
Derek
