I was looking at a scan I did yesterday and most of the wb readings show 14.8-15.0, which is lean, and the NB o2 is reading in the 500's which makes sense, but then in the same cell on my ltft table its showing negative values, so its pulling fuel right? Why would it be pulling fuel if both sensors show a lean condition?
So either im thinking of this the wrong way or something isnt right. Posted the log if anyone wants to look at it for me.
edit: err unless high 500s is sligthly rich I guess that would a lil more sense
