Write entire on 2013 GPEC2

Hi

I just installed a computer from another 2013 Challenger and now I can't flash my tunes on it. It says the operating system ID,s are different. How am I able to flash? The computer came from the same year challenger but it was from a 6.4l and I have 5.7 manual.


thanks

your credits go to the vin. which assuming you put to the real vin of the car which was on your old ecm. the new ecm has different vin so you will need to apply more credits. and as far as operating system being different best thing to do i would say is keep the operating system the way it is and make appropriate changes needed to it
