Z32 idle problem

[kcolocar]

Hello, I've been trying to figure out how to set my idle to be 14.7 with the feature pack.

I have 740cc injectors (340cc stock) and a selin set to avg mode. My K is doubled since the selin is at avg. My TIM is at 315. My latency is at 690. Cruising at closed loop is in the mid 13s-14s afr.

My problem is that anytime I lean out my latency until the afr is 15, my STFT will shoot to >10%. If I leave it like this for a few minutes, it'll transfer to the LTFT. Once this happens, the afr will drop to the 12s. My idle stays from 12-13 until I clear the LTFT, at which time it goes up to 14.7-15 and the whole process starts again. My idle smell likes gas hanging out in the 12-13afr and I want to get this figured out. I appreciate any help.

STFT/LTFT numbers are only valid during closed loop

At idle these numbers are not fuel trims so dont take notice of them then

Make sure trims around 0% at cruise STFT/LTFT only
