    that chart is telling the ECM that "at X rpm divided by Y kph the transmission is in _____ gear."

    did you change the ratios in your transmission?

    No, I haven't changed anything, I'm just curious about what it's for and what would happen if it's modified.
    Tanks for the quick reply

    If I change the tire size, should I adjust that table? I have 26" tires (236/60/15)?

    We can use the nv ratio, or estimated gear, for boost by gear.
