Ahh, I get it. Anyways those are the definition files for the 93 Camaro and the 92-93 Vette. People swap computers between the two all the time so I figured they used the same def file but now I see they dont. Now I'm wondering what's the diff because I have the one for the Camaro and I dont want to spend another $20 if theyre the same. 94-95 use the same diff file $EE.

Email Ion (madz28.com) or Alvin (pcmforless). I googled and the only thing I found was other people asking the same question - no answers.

The difference is that the Corvette ECM uses specific hard coding for the communications to the CCM in 90 and 91. The F body cars did not require this.

Dohhh I was brain dead last night But yes, its the 92/93 LT1 cars, in any case the difference is the CCM code required for the Y body cars.
