    You can change VIN using V7 scantool.

    Reading PCM flash does not require an ECM license.

    JoeCar - thanks for the reply. You just saved me $125.
    I am brand new to EFILive and this task will be my 1st attempt at using it.
    I am considering attempting to build a bench cable for LMM ECM but I cannot find how to match the serial RS232 pins up to the PCM just yet. The link i found In this forum is broken and gives a 404 not found.
    Thanks again.
