Re: What kind of computer/mass air set up are you guys using?
What year is your car? 94-95, I would suggest swapping to a fox body PCM (
A9L calibration for example) or getting it tuned.. tune is a must for 94-95s..
for the fox bodies..
I am using pro-M / diablosport chipped ECU --
Stock PCM, pro-M and 24# injectors.. put out 292 HP on a loaded dyno.. on a 15.1 or so A/F ratio (LEAN)
tuned in (diablosport chip + custom dyno tune) its locked in about 13.0:1 A/F and is up to 310 HP..(chart in sig..)
According to the tuner the majority of why I was running lean was due to the aftermarket mass air meter -- bbunt, I'd bet with a tune your car would haul ***, and I had the same cold start idle issue pre-tune
-> as for your question, the FMS mass air will work, but EEC IV is rather .. outdated.. to be sure/for best performance.. have someone tune it/ or at least find someone with a wideband o2 system, and use a mini AFC to dial in the correct A/F ratio..
