has anyone heard of this or perform this on an M20? will this only work with a 081 ecu?
MAF swap from a E36 320i. 4pin (13 62 1 733 678) (70mm diameter)
Car is ´86 325i euro(9.7compression) (ecu 081)
no O2 input into ECU either
assume everything else stock.
Installation of MAF:
12v from fuel pump relay, signal wire to original AFM signal wire into ecu(grey yellow, #7 on ecu end).
ground to ground.
Results: no problems and complete stock drivability.
good throttle response, and probably some HP
Note : this is a BOSCH M50B20 MAF and no other MAF may work, there is almost a 100% chance that other MAF´s will not work as easily.
This MAF is also found on E32 850i, E32 750i, E34 520i, and E36 M50 320i
