AEM FIC tuning tips
Thought I would start a thread so anyone who has an AEM FIC installed can share what they know.
I will start with what I have, I am running a customized Zage turbo kit running around 8psi at sea level. My car right now is running like it should from the factory I am running the z107 firmware and my injector response time is set to 810us on stock injectors and your MAF clamp should be set at 4.95v here is my tune so far as I may need to add some fuel up top but I haven't been there to find out yet,this is what it looks like in the program.

^ Thank you for earlier I put 6's in all my 0's on the fuel map and it really cleaned everything up nice after I fixed my MAF clamp.

If you guys right click the Fuel map window there is an option to change the fuel injector size. has anyone messed with this?
BTW Thanks Kou

Not me yet. But i would think you would need a tune that is working with stock injectors then it would be easier to increase the size.

I'm not using stock injectors. I've tried several things to get my car to idle right.
With how i have it setup now, I'm running 14.7s AFR but the car still bogs down to 500-600 rpms and stalls when the engine is warm. I'm running the 1zz injectors, I've tried increasing and decreasing the response timing, I've tried to increase the injector size on the fuel map, I've tried negative numbers in the fuel map (reduces the amount of fuel used by injectors?), nothing i do gets the car to idle like stock...

I can only suggest you open a new file copy my tune put it on the FIC see how it idles then adjust for the fuel injectors. You can always go back to your original file.

Started the car, letting it warm up now. Everything looking great so far. Once its warm I'm going to drive it around for a bit. Can't wait!

With the FIC and the Boomslang harness, how do i connect the bypass harness?
EDIT: This is crazy, car idles great, then out of nowhere RPMs fall below 600 and the car stalls...any ideas guys?

did you adjust for injector size. how was it to drive with the tune I gave you? If you let it idle until its warm will it stall or is it when you are coming to a stop?

Do you have the stock throttle body? do you have a vacuum leak?
