High AFR 15.9 at idle. Thoughts?
High AFR 15.9 at idle. Thoughts? I have an 02 TA with a built motor and I just hooked up my wideband to an AFR gauge for the first time and my AFR is 15.9 at idle.
Isn't this high?
My motor is 430LSX with AFR 225 heads, fast 102 etc

I found if you push the decimal point out on the VE table out to like 2-3 places you can get it dialed in really nice.
my turbo truck idles at 13.8 until it reaches 120*F and then creeps up to 15.5 at 160+

The OLSD table in the tune adds fuel until you warm up. At least it should. Cold car needs more fuel to run (as well as airflow). As it warms up it needs less of both.
Yes. Set your O2 switch points lower in the idle airflow modes. 450 is stoich. Try 300, then 250, etc. it will stay closed loop and not try to trim higher
