AEM Fuel and Ignition Controller wiring
Posted: July 14th, 2012, 12:26 am
I think whoever wrote the electical diagram for the ECU should be beat with a sack of oranges. (Rant aside)
I recently purchased an AEM F/IC for $160 brand new local. Good deal, and pretty much gives me everything I could need (for now). However, there's a lack of MX-3 ECU wiring diagrams.
I think I've got them all, but I'd like some second opinions. All of the connections are being made near the ECU on the wiring harness.
Fuel Injectors (1-6): orange, yellow/violet, yellow/black, orange/white, yellow/black, gray
O2 sensors: blue/white, white
TPS: green/yellow
Crank position sensor: light gray (?)
G and NE1: purple/green, purple white
VAF: ???
IAT: red/black
Crank position sensor I am unsure of. It's a pain and a half trying to understand that schematic on the electrical diagram.
More specifically for the VAF, which wire is for airflow? May use the MAP or add a MAF and have an analog output simulate the VAF, so need to know.
Please and thank you.
