Hi Shiv,
I noticed that the Primary open loop fueling AFR Target in tables is about 12.5.
However in a couple of post you say you target 11.6-11.8 AFR at WOT on Gasoline.
Most peoples logs show AFR in mid to high 11 for AFR. And low LTFT.
Jusr wontering why its not closer to target in Fueling table ie 12.5
Is this due to the inaccuracy of stock o2 sensor you talk about above.
Thanks Steve
