    Default 01290005 custom operating system

    I have a 2004 lS1 Holden manual 12225074 using 7.5 software and want to upgrade to 01290005 operating system where can I find the operating system to load into the PCM with 7.5.

    Found the operating system under EFILive. V7.5 >calibrations>LS1B> Custom, however it will not open, says "File type not supported."

    Joecar thanks for the prompt response. The version I am using is V7-5-7 build 299 which works fine with an existing 01290005 auto tune however I now need to set up a manual tune.

    Yortt: ^ this is where you should be loading the COS file from.

    Note: calibration/tune files are either .ctz or .tun and not .calz.


    GMTECH4: thanks.
