Hi All, just a few questions on what to change when getting into PROM tuning.
I have a 1991 Camaro RS, airbag, ac/heat, electric windows, tbi, all the fun stuff.
I have the original PROM $61 and I was wondering which flags I have to change during the engine swap. I will be changing from TBI to FiTech EFI and using an additional fuel pump, removing the charcoal canister and the cat as well as replacing the exhaust headers (currently have some vacuum? lines running on them). The FiTech system self tunes the air/fuel ratio with it's own computer and o2 bungs.
Any help in the right direction would be great, thanks!!
@TunedPerformance Thanks for the reply! My apologies, Spark advance is also handled on the FiTech system as well (msd ignition box). I guess the better question here is: which flags do I have to disable to remove check engine lights

Not sure what your asking if your not using $61 mask you won’t have any malfunctions. Unless you removed the egr and need to max the egr speed on and or malf switch 32. To disable the check engine light cut a5 brown white wire at the ecm.
