    The Shelby setup use all the stock GM sensors. They added one more. It is a Rough Road Sensor. It as a G sensor mounted Verticaly.

    The 99 uses the stock crank and cam sensors. It used the stock coils.
    The 2001 the Shelby Series II used the later style engine with 8 coils and the newer cranks sensors. This car was just a prototype, so I can't get my hands on the Cal ID.

    I have a 2000 crank sensor a mapped out, but I have a raw mechanical version, not the electrical version yet.

    Anyway much of this is

    I have here the early Delphi one, then the two Seimens type, the ones you had the pictures of and the earlier one that was similar shape to the LS1 PCM, unfortunately totally different inside.

    Thanks for your input.

    Cheers,

    Lyndon has the software to tune


    In 2000 they repositioned the crank sensors and redesigned the notches on the crank. So the block and PCM have to match at this time

    All 2000 to 2003 run the same PCM. It is the SIEMENS. They had several SERV. NO. but they all supersede to one number. The PCM in my hand is a 12562481 and I know it is not the latest and greatest number.

    All 2004 and 2005 FWD used a Serv. NO. 12587465 PCM. I think the is a E22, but it is not GMLAN. This has Transmission functions


    This is a link to some PCM type and Information on all GM PCM's

    "especially when the Shelby 4.0L Northstar uses an LS1 PCM"

    OK We will start with that PCM
