Single Afm On A Rb26

[Bsa]

Thanks boostjunky everything is sorted but wiring and turbo but Sunday I hope everything is under controll

Simply bridge both the afm signal wires to the 1 afm and take car of the rest in tuning. Pretty simple really.

You will get a terrible run off an untuned ecu; just because you set it up to read one AFM doesnt mean it will fuel it even close. In twin configuration each is reading half the airflow obviously, if you use the same afm with only one intake it will be reading that you are at double the airflow because its all coming in that one pipe not two. You have also halved your afm limit.

If you then send this load reading to the ecu it will overfuel.

I think you almost do want the ecu to half the value. Have a think about it as im no expert. You could probably tune around it but you should lose your afm limit still.

This is also a way to run the 26 power fc on the 25 or would the high injector impedance not work out?

[Bsa]

Rb26 already reads high impedance

Not to bring up an old thread buuut. If I am running an rb20 with an AP engineering PowerFC, Z32 AFM and rb26 injector mod, could I still use this on an RB26 swap to use the twins but only run one AFM or would I have issues? I want to get the motor in as quick and easy as possible I don't foresee problems as all i'm really going to be doing is a basic engine swap?

help?
