Popped in a unit from a 97 Firebird tonight. It runs very well. Now, i just have to get the tuner(have not decided yet between DHP, or HPTuners). It's just nice to know that it was indeed a "plug and play" deal. I just made sure that the ECU was from a non-supercharged vehicle with a 3.8 and auto trans...that way it was as close to my vehicle as possible, not requiring an immediate tune to run worth a crap. I hooked up my scanner, and wholy crap!!....there are a TON more options in this unit than the 96 ecu!! Appartently, the s/c boneville ecu that I have in the shop is the SAME part number as the n/a 97 Firebird....but I'm guessing a different tune in it. I just needed something to run "out of the box" for now....and bird ECU fit's the bill! Apparently, the 97 ECU was widely used on various sized 97-only gm V6 vehicles. A rare, one-year-shot kinda deal.
Anyway, I'm happy the ECU swap went so easy. Now, just curious what tuner is the preferred one for this setup? DHP? HPTuners?
Philly....what worked best for you?
Thanks. Things are looking better now
