    Default Engine Code Segment for L29 454

    Hello all,

    I'm trying to help a friend out and return his ecm to a stock/factory configuration. According to GM's tis website he needs an engine code segment with a ID/part nbumber of 9364838 (preferred), 9374044, or 9388590 (these are for OS 9365085).

    Does anyone have any of these stock segments they would be will to send me?

    Thanks,
    Charles

    Do you own an EFILive box? This isn't just a $5 cable. Engine calibration is something the EFILive system can read from your current ECM.
