    Using Mello's formula (from https://www.ferrarichat.com/forum/threads/f1-clutch-wear-readings.622180/) of:

    Calculation of clutch wear percentage for Ferrari 360/430:
    Auto-calibrated closed clutch position - NEW closed clutch position / Clutch thickness (8.5 mm for 360, 5.6 mm for 430) * 100 = % wear on clutch

    And an Autel ODB report from my 2000 360 F1, is this the correct formula/calculation and resulting wear percentage?

    Here is the Autel report. Am I using the correct data points?

    Data are correct but your Formula is wrong.
    Should be : (A2-B2)/C2*D2

    Actually the formula is inorrect ..but haven't used the ap200 in over a year now

    Look for clutch position from new ..it may be a different data item.

    If that is truly new clutch position..70percenr worn


    New minus current ..result divided by 8.5
