    O2 Readings

    Can someone give me an idea what the O2 mV reading would be at and AFR of:

    11.0
    12.0
    13.0

    I just want a general idea.

    Thanks,

    Kane

    11.0=460-1100mv
    12.0=460-1100mv
    13.0=460-1100mv

    All of these are rough estimates
    It doesn't have to be perfect, it just needs to be done in two weeks...

    It is that wide so there is not a typical area like

    12.0 880-930

    or something like that?

    Something like that, which is why you need a wideband

    Narrowbands are absolutely worthless for readings at WOT. What I think is funny is all the people out there that claim that if they are reading around 890 mv or so at WOT then thats considered "close" for n/a and I have seen mine reading around 890 mv and my afr was in the low 11 range so you just never know. Anything other than stoich which they are accurate at it's anybody's guess.

    I do have a wideband in the car and around 12.0 my O2's are around 890-920. I just had someone say they usually see boosted cars in the high 900's to almost 1000 and I did not think that was right but I guess every car is different depending on where the O2 is located.

    Every car is different because narrowband o2's were never meant for accurate at wot.
