    Default Problem logging VSS

    Major issue

    How come VSS wont log speeds over 255kmph which is 155mph?
    I have removed the speed limiter and was trapped at 171mph but the log file only goes to 155...

    I know the tune is ok because I went faster than that. Is this an efilive limit or something to do with OBDII only sending a max of 155 out the serial?

    Help.. It broke my nice standing mile logged run.

    My understanding is that VSS is unsigned 8 bits, so it only goes up to 255 k/hr.
