    OS Upgrading to latest version?

    Where or how would i find out what the latest version of OS for my car is? Is there a site on GM somewhere that tells us this?

    People like me that are nice enough to flash it to your PCM for $42 plus $12 shipping.

    Its really not a BIN that you can just flash to an existing PCM unless the OS ID is one of the previous OS ID for that PCM... Let me explain .>>>

    This VIN > 2G2WR524041289814
    Has this CAL ID trail .>>>

    12588928
    12588931
    N/A
    CORRECTS TIP IN HESITATION ON ACCELERATION - COLD ENGINE

    12584053
    12584056
    N/A
    New calibration to address clunk noise occurring at shutdown

    12582182
    12582185
    N/A
    NEW CALIBRATION IMPROVES TRANSMISSION SHIFT FEEL.

    12575591
    *No Calibration Data Available
    N/A
    Control module
    <<<<<<<<<<<<&l t;<<<<<<<<<<<

    So, if you have 12584056 You can flash 12588931 over the top of it if someone just sent you the stock file...

    Look at the BIN repository... IF you see a BIN there that is above your current BIN, you should be able to flash that current BIN over the exisiting. The BOOTLOADERS will match. If you try to flash a non-matching BIN, you will get an error that the OS ID or the BOOTLOADER cannot be found.

    If you want a PCM changed to like M6 to A4, I can flash that with the Tech2 and SPS software.
