If you have the harness stay with the same year ECM (96-97 should be the same). You just need to program out all the pollution and rear O2s. Also easy enough to delete the MAS and go SD. But if you go to an earlier ECM 94-95 I think you would need to change the pin configurations. I wouldn't bother going 92-93, no trans controls, batch fire. Too much extra work!
What are you buying? I got a nice aftermarket ECM designed for LT1s I'll sell you!
Jeff, it this car in Vegas? If so, PM me!
