    Default Aem failsafe gauge not serial

    I bought the aem failsafe gauge NOT realizing it is NOT serial capable. It seems so nice I want to try it , but it is not serial and I never bothered with analog. Anybody use one of these on here yet?
    THANKS

    Well , I installed the failsafe gauge and hooked it up and set my air fuel/ boost failsafe settings to a warning light and all seems great... EXCEPT I have been using serial for years and I am analog dumb. ANY help would be great. THANKS!

    This is an AEM P/N 30-4900

    I'll derive a V->AFR equation...

    what fuel are you running (E00, E10, E85)...?

    thanks!!!
    E10

    Any other info on getting this logging correctly would be awesome. I am more than rusty on this stuff. I went lazy and serial early on and have not had to create anything on my own . THANKS so much Joecar!

    While I have good eyes on it, I wired the white to the A1+ and the Brown to the A1- on the V2. Sound good?

    That page already shows the equation for AFR(gasoline) based on stoich AFR 14.6.

    The equation for lambda is: lambda = 0.1625*V + 0.49875
