    Autometers are programmable.
    We'll need to know the programmed Lambda/AFR range.

    The slope & intercept are needed in order to convert voltage to afr or lambda.

    Example:
    4 volts = 20 afr
    0 volts = 10 afr
    stoich afr =14.7
    voltage from WBO2 = 1.88

    (20-10)/(0-4) = 2.5 (slope)
    0 volts = 10 (intercept)
    (1.88*2.5)+10 = 14.7

    Preferably you want to know the programmed Lambda slope & intercept because
    any stoich AFR value can be converted from that.

    Link in the bottom of my sig has more.
