    voltage offset correction not enough ?

    get 4.92v@ analog out, 4.78v@Scanner used offset correction below, but the correction wasnt enough to bring AFR up to free air max

    4.92-4.78 = .15

    .15/.625 = .24

    volts/.625 + 10.24 = 17.85 AFR

    had to bring up correction to 10.36 before HPT would read free air AFR of 18....WTF ??

    should be scanner voltage minus 5v, not actual analog voltage...

    5.00v-4.78v = .22

    .22/.625 = .352

    volts/.625 + 10.352

    that's why it took 10.36 to get 18 AFR in free air


    although the formulas confuse me...why wouldnt you plug in the actual voltage you get instead of what you're suppose to get ?
