    Logging Copperhead AFR

    I have been trying to log AFR both on the table and in a histogram for a few days. What do I need to do to get afr? Do I need a formula to get it from lambda? The lambda show an insanely large number. Im new to this and pretty lost with the logging or i might just be an idiot. Undecided.

    Thanks in advance.

    In the same boat you are with getting a good config setup to log this ecu
    Current toy- 97 SCSB OBS chevy forged 6.0/4l80 combo with a bit of boost..currently back under the knife

    To many previous vehicles to list

    Lambda has to be divided by something like 2,000,000,000 to get the correct value. Multiply lambda by the programmed Stoich AFR (should be 14.08:1)listed under Engine>Fuel>General to get actual AFR if you want to see it.

    I wonder when the 2.25 beta version of the scanner will be available?

    Blazin72,

    Do you know the exact value or happen to have an example of the equation?

    I think I got it. I divide the given number by 2,000,000,000 and then multiply by 14.08. Cant figure out how it wants it listed in the filter.

    You don't actually need to know AFR, lambda is what everything in the tune is based off anyway.

    Do you or anyone else know how to setup the equation to get to lambda? I can't seem to get it to work.
