Hey all, I am new to the FIC and having a i little bit of issue. I installed the FIC on the car before adding the turbo. The car idled just like stock. Now with the turbo I see the the AFR are all over the place at idle. I am using stock injectors also. I am wondering what i need to focus on to fix the crazy idle. I am also wondering if the two halfs of the downpipe are sealing properly. I've read that a exhaust leak can cause a wideband to read lean. My wideband never read below 14.6 and my engine didn't seem to have a hard time running either.

Thanks all.

If you haven't changed your injectors and suddenly your idle/afr is all over the place after AFR, then you have screwed something up during the turbo install. There should be no difference whatsoever at idle because your car will still be in vacuum. Unless of course your AEM f/IC vacuum line isn't hooked up to your intake manifold.

I assumed something was wrong with the turbo install. Maybe an exhaust leak pre wideband. I didn't have the wideband hooked up before the turbo install so i really can't compare it to anything.

Eric, Did you get your issues sorted out?

Well now at idle and cruising the wideband stays around 14.7 but still goes up and down from there .8 points. At WOT the car does go extremely rich, sometimes as low as 10ish, but this i think just needs to be tuned out.

That bouncing around 14.7 is normal closed loop behavior, so that is good. Sounds like you just need to get your tuning worked out. Good luck with it.
