6 Speed S4 Posted April 11, 2008 Report Share Posted April 11, 2008 My buddy just bought a 93 Z28 Automatic, he has a full exhaust and intake and wants an ecu for it that will gain some extra power. Any idea or websites that sell these? Quote Link to comment Share on other sites More sharing options...
XChris1632X Posted April 11, 2008 Report Share Posted April 11, 2008 get on camaroz28.com there are plenty of people who tune them with Lt1 edit. or for like 150.00 you can just buy LT1 edit and download a map for those mods. LT1 edit is the program Ive heard 90% of Lt1 owners using. You dont buy a new ECU, you reprogram your existing one. Quote Link to comment Share on other sites More sharing options...

Whole different deal on the 93's (batch fire, no MAF, different trannies). If all the guy has is and intake and exhaust, do not have him waste money on a reprogrammed chip for his PCM (powertrain control module...not refered to ECU's in LT1's). There won't be any useful gains doing so. Long-Tube headers would be the next logical step. As for editing the PCM on 94-97 cars; you can use LT1_Edit for 94-95 OBD-I Tunercat for 94-95 OBD-I LT1_Edit for OBD-II 96-97 (different program than OBD-I). 93-94's have a OBD-I connector under the dash. 95's have OBD-II connector w/ OBD-I PCM, and use a different cable than any of the other years.

XChris1632X Posted April 13, 2008 Report Share Posted April 13, 2008 Thats my bad. I was just seeing LT1 in my head and not even paying attention to what year it was. Sorry for the mis-guidance. Quote Link to comment Share on other sites More sharing options...
