car not responding to correction?
 

i have my SAFCII installed but when I try to set +/- and it doesnt show any correction or change at all.

what could be wired wrong?

and is there an easy way to tune the AFC with the S4 TPS? or is there a way I can swap to s5 TPS so its not 100% at light half throttle.

Hard to say. You should go back and do what is usually recommended. Make sure you selected FLAP and the arrow is UP AND TO THE RIGHT and the IN is 05 and OUT is 05.

I can sit at idle and turn the lowest rpm to a minus and make the car die. I mean go minus 10 and wait a moment or so. The rpm should drop some then keep at it til you put in say a minus 20 and at that setting I'd surely expect the rpms to have changed. If they are not, it's wired wrong or the settings are wrong.

Curious. What exactly did you mean when you say you set a plus or minus and it does not show up. You mean when you go to MONITOR you don't see any changes? I think that's what you mean but thought to ask just in case.
