FMU question

[92TurboGS]

Im thinking of using a fmu on my car for fuel tuning. So i can use a smaller injector and no s-afc , has anyone put a fmu on a dsm that has good results? let me know, thanks.

I have already replied to your question in the previous thread. Anyway, what car do you have? Is it a N/T car with turbo kit? For a turbo car, you dont want an FMU because it's not static rate FPR. Depending on what is the raising rate of the FMU, you can still get it to work with some fuel control but only at very low boost level and make tuning a b*tch. High raising rate FMU is not possible for a turbo car because even with an AFC, you may not be able to lean it enough.
