I have a Supercharged 3.5L 2008 Chrysler 300. Its also been NAG1 swapped. Anyway... Long story short Im adding a MTCM. I restored it back to factory and saved my backup to the PC. Went to reload my tune onto the tool but it will not due to file types. The new backup is .frg to where the old backup and the tune are both in .drg format. Will it hurt if I load my old backup (which had the stock TCM) just to upload the supercharger tune? I mean all I did was swap the TCMs lol.. I renamed the new backup file incase your wondering about it being similar.


PCM_05187031AH - NAG1.drg - Original Backup before TCM Swap
PCM_05187031AH - NAG1 TWSC.drg - Tune file for Supercharger
PCM_05187031AH - NAG1 - MTCM.frg - New Backup with MTCM installed

Figured it out kind of. Its stuck in demo mode and wont update for vehicle type. Says not married now, but it did say demo. The tool keeps cycling through the vehicle selection page. I tried updating the tool it says that its up to date...... Same issue still.

what happens when you try to select your vehicle from the options menu?
if its married in demo, go to the menu and restore the demo backup first to unlock it then change vehicle type.
