Which AF reading am I supposed to be using during Open Loop readings? I remember reading that I was supposed to be using AF.Corrected but not sure if that is still the case.

Just look at AF, AF.cor is for the Civic SI.

Sorry for asking the same question in a different way. I want to know the difference between AF, AF.Cor, and a 'true' Wideband O2 reading, for an S2000.

How does the standard AF readout for an S2000 compare to a properly functioning Wideband O2 during AFR during Open Loop fuel tuning? Is it so far off from a properly reading Wideband O2 (during Open Loop fuel tuning) that it should be disregarded?

Prior posts over many years, seemed to indicate that using the standard AF readout for S2000 Open Loop fuel tuning would result in way too lean of a tune, so for some time, AF.Cor was the recommended readout to consider. Does more recent data indicate this is not the case?

Ignore af corrected. Only look at the AF. AF corrected was just for the SI.

OK, thanks. Is the standard AF accurate enough to tune Open Loop fueling? Would love to keep it simple and not have to integrate a Wideband O2.

Yes it should be.

Thanks!
