    Well guys I finally wired up the input speed sensor, did the segment swap, and shit a chicken. It works! That was too easy, thanks again Lextech for randomly having a compatible tune and Eagle Mark for giving the Barney style walk through.

    Who do we submit Lextech's tune to to get it loaded into the repository?

    Good job


    A full flash is only needed if you're changing OS.

    Thanks Joe, I actually didn't have to bother you directly for this one.

    Sig is updated and tune is submitted. Shift points are a little off which is odd, because Lextech's tune is from a 4.10 truck and mine is also a 4.10 truck. Also, do I need to change H4593? It's a 4L80E swap specific thing for the TCC. Totally digging the extra RPMs in 4th gear now.

    So the speedo segment updated the trans ratios accordingly, thought maybe it was missing that. If it still ASSumes stock tire size, maybe that's why it shifts a couple hundred early at WOT? It's not shifting at its commanded 5100 WOT. The rest is so close I can't yet tell if it is off.

    As far as I can tell, the 4L60 is a Yes and the 4L80 is a No for H4593.

    This should never be touched unless you change your transmission type from a 4l60e to 4l80e.
    Only the following values may be entered into this table:
    - No
    - Yes
