    Overdrive ratio parameter

    I have 94 suburban with 6395/OE/BDHF. there is a parameter "overdrive ratio" with a number of 42.686. I assume it is used in some calculation. Anyone know what that represents? It does not directly represent the overdrive ratio.

    Would you mind sharing what you found? I'm curious but don't have time to dig into the hack.

    Without going through all the calcs and filters, take your tire revs per mile and multiply by your rear ratio and then divide by 60 and that is the n
    umber you put inthe box.
