Just installed my Innovative wideband about a week ago. Now I can finally tune my idle AFR. I'm gonna use the coolant temp. option on the PFC. I'm running 850cc and 1680cc injectors with 43 psi fuel. I'm also running all 9s with AF option turned OFF on PFC. I'm running about 11:2 right now with nice steady idle. If I try to lean it out the idle gets lumpy. I know thats really rich. Am I going about this the wrong way? DO I need to hook up the data logit to actually tune out each individual cells? Any help would be great. Thanks!

 

I'm confused about your approach, what is the coolant temp option? what is the AF option?

This topic has been covered out the you know what, but here's a brief how to. Adjust the PIM map for 1000 rpm ..., you can go only so lean without playing with timing. Timing is complex so I'll let you search for those adjustments.
