Rb25Det S2 Into R32 - Afm Problems

[rb_rb]

I have an rb25det s2 engine that I have wired up using my r32 rb25de loom. I wired up the coils, injectors and tps with no troubles, and the car starts up and runs on all 6.

Only problem I have is that when the AFM is connected it runs poorly, barely idles and when i try and rev it, it just spits/backfires. But when AFM is unplugged it will idle and rev without hesitation but not past 2500rpm (limp mode).

The afm plug on the loom was originally 4 wires but the rb25 s2 afm plug is 3 wires. I followed the afm pinout on webbers rb guide to wire the plug correctly.

Any help or tips would be appreciated!

I think the proper AFM would work. Look for a green label AFM
