Basicly Alex i just want to know if early (1985) E30 325i managment shuts down or anything when it sences what it thinks is a far too large amount of air going thru the airflow meter, or if it just maxes out and stays at the max amount.

Just some managment systems cut the ign etc when they sence boost or a certain amount of boost, thinking its a AFM error.

And if so, how you trick the AFM signal to stop it doing so...

foreigneRS--

Yup, E30 is that shape.

The megasquirt looks good, but ive no time (or skill ) to make it, and a bodge is more than good enough, trust me
