    Are you getting an immediate MAF DTC...?

    The E40 COS is on the Upgrade OS tab... (go View->Show Calibration Window, click on UPgrade OS tab).

    Also, if it does not appear when you open the file, close it and plug your V2 in first, then open the tune again. Certain COS/DSPx upgrades are only visible with the V2 plugged in.
