    8l45 (8l90 too) cruise control not working and over sensitive stabilitrak info

    Apparently when you change the tire size and or gear ratio it only adjusts the vss tune from the transmission.
    There is a vss adjustment that needs to be done for the wheel sensor (abs sensor I think) and as of right now that is not available with hptuner even with the tcm unlocked.

    I?ve sent hptuner an email to see if they can identify this and make it available for adjustment.

    abs vss is not tunable yet. So it is reading different than the rest of the tune when you adjust the speedo (gears or tires). So Hptuner ticket started and they are going to look into adding the abs vss thing to be able to be tuned.
