Hey Volvo Gang,
I'm from DTMpower.net... no I didn't get lost
In any case, some info for all those who wonder: e30 generation BMW shares the same injection computer system with Volvo - Bosch Motronic. I already found out that stock Bosch injectors fro B230 Engine (white tops)fit the M3 and flow about 30-40% more fuel than stock ones.
Now, what does that engine use for intake air measuring? I hear it's so-called AMM - Air Mass Meter. BMW M3 uses AFM - Air Flow Meter... Any difference between both? I hear AFM is not precise or reliable. Plus, it's useless when you boost the engine. (It's a flapper door attached to a resistor and operated by vaccum pressure of the intake manifold, I imagine once you boost the engine the system would be totally out of wack unless you replace the return spring for the flapper for a much stiffer one, then calibration becomes a problem) Would someone please explain to me how Volvo's AMM works?? Thank you much!
