    Default os 12667378 and segments 12666850, 12666622

    Hello all, I don't post often at all but I hope someone can help me here.

    2015 lml, operating system 12667378

    I have a calibration on hand with engine operation segment 12666850 and engine diagnostic segment 12666622

    I have a truck with engine operation 12666851 and engine diagnostic segment 12666623

    the segments I do have are not listed at all in the gm calibration history. will it be ok to use the segments I have?

    or does anyone have a calibration with the correct segments?
