But I seem to be getting some weird jumps in AFR & ST Fuel Trims. I'm running Stg1 91 Tune, just swapped back to oem exhaust manifold. LTFT seems to be pretty stable. Open loop AFR seems to be a bit lean, I was used to seeing like low 12s now I'm seeing high 12s even low to mid 13s. Also when I'm coming to a stop @ idle I see the AFR jump down to like 13.5 then jump up to 16, seems to be acting weird I don't recall this while on stg2.

Dont worry about stft it varies with heap of factors like load throttle temp ect, long term fuel trim is the one you watch its the average of stft over a sliding time window and the difference between commanded and actual afr. yours looks ok.

When your rolling downhill or to a stop the momentum of car is used to turn engine over and the ecu shuts off fueling to save fuel so you will see afr go to high values like 20.

Looks like you still have some knock arroind 3000 to 3400 loads 0.8 to 1.1 , probavly what knocking your iam down.

and some 4800-5200 loads around 1
