aem fuel and ignition controller

Boosted RS-t · Jan 18, 2008

Im goin to be getting the aem fuel and ignition controller for my car soon. I was wondering if anyone else has opinions on this module. I have a 420A thats built and boosted and i wanna get rid of this fmu and from what i understand i dont need a fmu or regulator when i use this. is this correct? thanks any help will be appreciated guys.

I don't know too much about it, but I think you still need a 1:1 AFPR on your car to use the F/IC. I have read about some 420a-t people using it with fantastic results so I would say go for it. It's under $500 for the module and it can handle tuning up to 25 psi.

does the 420a use a 12:1 or a 1:1 i know that its different than the 4g63 but i always get confused. Sorry if i sound retarded. But ill be the first to admit. i dont know it all lol. Thank you for the help totaleclipse_05

You use a 1:1 AFPR if you are going to use Megasquirt, AEM F/IC, and Portfueler (I think).

A 12:1 ratio would be used for the FMU if you were going to use the stock injectors for a basic 8 psi or less fuel setup for turbo.
