I searched the internet but not much luck with 91 rx-7 aslo I emailed aem didn't get much help from them since its a universal application and they don't have my wiring diagram. In there words " It is up to you or a 3rd party you employ to wire the unit to your vehicle's pinout.... our suggestion is to proceed with trial and error. Do not wire the whole system up and test when you are done. Wire each feature /input one by one and test the application after each intercept or tap is made. For Reals???

I'm trying to figure out how to wire the CAS, dilemma is there is only one sensor crank intercept but the rotary CAS has 2 sensors (24 tooth and 2 tooth). Anyone in the forum has tried or know someone who install the aem fuel controller, I would appreciate the help.
