I'm thinking about installing a '94 LT1 into my 87 firebird. My major concern is about bypassing the VATS system. I live in Southwestern Ontario and currently know no one who can reprogram the ECM. Any help is appriciated. Thanks guys!
Does anyone know where I can have the VATS programmed out of my PCM? Alternatively, is there a VATS bypass module I can get? (were all '94 LT1's VATS equipped, and OBD1??) Any help is much appreciated!!
Painless wiring makes a bypass module for vats. I am using one on my LT1. I plan on getting my Computer reprogrammed when I get some money. I will be using www.pcmforless.com to program mine. I also will have vats removed. If you have any questions you can e-mail me, and I will be glad to help.

Ion at www.madz28.com does some great work. You can ship him your PCM and have it back in week. He programmed mine and it turned out to be a major difference. His prices are extremely reasonable.

Ok, I have one for ya. We have a 94 caprice police package wagon and its having a VATs issue. Car has been in service 4 the school since new. No dumb mods..
Batt was unpluged while some head work was done and now it will fire up and run then shut off in 2-3 seconds.
It has the chrome lock and round keys.
the code has something to do with inj pulse shutdown or something like that..
Its kind of weird, called the dealer and they said that car doesnt have VATS, we know that but its not what the scanner is telling us!!!!! we maybe calling you!!
