    Fast Wb

    Can a Fast wideband O2 be set up as a lambda sensor? I just got calibrated success, and I am trying to get set up to use it. I have a FAST wideband, but I don't have any info to set it up as a lambda sensor

    Thanks in advance

    My LC1 allows you to output either AFR or Lambda, so I don't see why you wouldn't be able to do the same with the Fast. Check the program options.
    When arguing with an idiot, make sure he isn't doing the same thing....

    I think I found the correct values to log a Fast wideband as lambda, since the O2 sensor is a Bosch LSU4.9. This is what I found:



    So I entered the values like this:



    Figuring Lambda at 14.13 IIRC to account for E10.

    Does this look correct?

    Thanks
