    Tune file request e38 ecm

    Looked everywhere including tune repository.

    I?m needing an e38 tune file with OS 12614088 from a manual transfer case vehicle.

    If anyone has one can you please post!


    Needing to do a segment swap and not having any luck finding!

    E38s were used from 2006 thru 2020, can you narrow it down a little bit for those of us who don't have every OS ID memorized?

    How about this?

    2007 Yukon 1500 1GKFK63817J314905 6.2 A6 1376673403.hpt

    Verified in TIS that there's no file for a TCCM for this VIN, and U0102 is No Error...

    It?s for an 2007. Checked over that tune file and it won?t work as it?s awd one speed tcase.

    Back story.

    Going in a Jeep with 4wd low (manual 2speed transfer case)


    2007 with a manual transfer case used the e38 to receive a 4wd low signal via switch, so need to find that hp file with the same OS to get that specific input to work.

    I do appreciate the help! Thank you in advance!
