Which MAF do I use?

[i_build]

M52B28 from a 96 328, 413 ECU because it was switched to OBD 1, M50 Intake Manifold... with Pink top injectors.

I purchased a MAF that said it would work for a 92-95 328i so that it would connect to the OBD1 MAF Plug (round). Without the MAF plugged in I get a steady good idle and with it plugged in the idle is unsteady and loops.

I did smoke test the system and there are no leaks... I'm just really confused as to how the 413 ecu with a 96 M52B28 and M50 Manifold with pink top injectors... all know how they should work together.

The DME looks like it has the stock M50 chip in it... is that the problem?

I'm confused and would appreciate some help.

Thank you in advance.

there is no 92-95 328i, and 1992 has different MAF and ecu than 93-95. Looks like you need to have top green injectors from 93-95 325i and the good known MAF from same years. Pink top injectors flow more and will be too rich with stock M50 chip.
