There's been a lot written about the benefits of an FMIC, particularly on hot days in chipped cars running 98 optimised maps.
Two things are running round my head about this though..
1) If you get a 98 optimised map, what happens if you run the car on 95 (or even 97) sometimes? Will the ECU just retard timing? What I'm getting at is there actually any benefit in taking a 95 program over a 98 regardless of which fuel you intend to run on?
2) If a 98 program gets more power through more agressive timing, would running standard ICs on a 95 program with 98 fuel balance each other off? I accept that the FMIC is ultimately better, but if your not trying to run agressive timing in the first place, would the use of 98 fuel balance off the drop in performance though increased air temps? Even if it does, are the further issues by not having the FMIC?
