Buddies ECM went bad so he had to replace. He had bought tunes from Dustin and vin lic but used my Efi v2. I went back to program and everything is the same but says the lic doesn't work? Any way to put the programs back in?
Do you mean you bought your original license from Dustin? or a second license today so that you can tune this truck?
Cheers
