What's this about the A/C and the F-body PCM? I'm using the F-body PCM for a '95 LT1 installed in a '76 Vette (C3) and am about to button up the A/C...should I be concerned about anything? It's mighty hot here in FL!

You can use the fbody pcm without any problems, but don't use an fbody based program for it or automatic a/c won't work. Just be sure to use a 94-95 vette program to start your tuning.d

Thanks for the info gents. In addition to the auto ac, I was wondering about the other guages working with the OBD-1 PCM, like the fuel monitoring system in the '96.

What base program is recommended?

I apoligize if this discussion has been already been beat to death in the past. If it has please steer me to the appropriate source.

Thanks again..........Jim

Guages will work fine, however you will get a blinking "SYS" in the dash as if your battery was low. The CCM doesn't like it when you put an OBDI PCM in there. It knows you're tricking it, hehe. Doesn't cause any problems... but you get that thing blinking all the time.

I have a base program for an LT4 if you need it. It's all the same tables as an OBDII LT4 program.
