Toyota MR2 Message Board - View Single Post - Question for RickyB: Progress on the Stock ECU MAF Project??

RickyB · 12-01-2007, 02:37 PM

I'm currently developing a speed density version of the ROM code. There are major differences between the 91-92 and 93-95 ECUs and I'm currently reverse-engineering the portions of the 93-95 code that is different from the 91-92 which I have fully decoded. This is evening/weekend work since my daily tuning work keeps me so busy. I am working with a well known member of the MR2 community and her car will be the first to run the stock gen2 ECU without an AFM.

As far as running with larger injectors, that is a trivial change even in the stock ECU code if you know how to do it. I have all the Techtom hardware and software and could easily be selling ROM tunes that go well beyond what anyone has done in this area so far. Problem is, all my dyno experiments show that the AFM flap door completely opens before 250rwhp and beyond that point you cannot provide a perfect tune. Given that, I will not provide ROM tunes until I have everything in place to do them to my standards.
