I think it's Air Fuel Feedback and Air Fuel Feedback Average.
If I see something I don't quite understand as far as trims and oxygen sensor voltages, I'll check generic OBD2 data. It kind of the equalizer.
There probably isn't one called "b1s1" because the upstream is likely a wideband sensor. The data is probably displayed in mA, not bolts like we've gotten used to.
