Looking around for answers before posting here but found nothing so far. So my 1g talon starts cold and idles at like 11.0/1 - 13.0/1 till it warms up. Then it sits from 14.7-15.2. Not abnormal i guess. Well when i try to rev the car it leans out to 16-17+ to the point to where my wideband wont even read anymore. Can anyone point me into the right direction?

Can you post a log? How are your fuel trims at idle?

Heres a log from cold start. My wideband in link says its reading 9.4 but it reads closer to 12 on the gauge. AFRest Seems to follow what the wideband does when i give the car throttle and leans out to 16+. In this log i didnt rev it much because i was trying to be easy incase there is a problem. The beginning of the log is idle warm up.

Only post logs of the car fully warned up. You need to redo your tps and BISS screw. The idle switch is going on off at idle. There must be something wrong with the wideband wiring or it's not setup or installed correctly.

Like said start with TPS, ISC position ect. That's some very low timing your running. -4 in the slider plus what the map looks like is mostly under 10 degrees at wot. I don't know what fuel your on ect but I run more timing in my 10:1 motor on a 62mm at 30psi+ but its on e85.

I didnt tune this car. Its just in a base map for now till the tuner gets around to me. I figured ISC reading 119-120 was weird. Im honestly unsure how to adjust it but ill do some research. Im sure theres 100s of posts about it. Tps being .03-.05 off would affect my issue?

Yes, the tps being off can and is throwing off your idle position switch because when the tps is showing 3% at idle, for example, the ecu thinks you're on the throttle and will adds** fuel inappropriately.

The car idles well. It just tweaks me out that it leans out like it does when given any revs. Could be the tune?
Ill readjust the TPS as well.
