crank relearn

[George C]

did you have the PCM flashed? I know you can't simply write a fbody tune onto a truck PCM without having it flashed, different OS, at least I'm 99% sure. There are a lot of different operating parameters between the two systems. I know you can use a truck pcm to run a fbody and visa-versa.

i took the truck computer and rewrote it with a Fbody vin and etc. "Write entire". no issue after that. only time i have ever had an issue and was when i tossed my pcm in a monte carlo and i left the vats on.
