    I think I have a data array that should produce a single northstar crank signal if placed in a loop with an output to a pin.
    {1, 0, 0, 0, 1, 0, 1, 0, 1, 0, 0, 0, 1, 0, 0, 0, 1, 0, 0, 0, 1, 0, 0, 0, 1, 0, 0, 0, 1, 0, 1, 0, 1, 0, 1, 0, 1, 0, 0, 0, 1, 0, 0, 0, 1, 0, 0, 0, 1, 0, 0, 0, 1, 0, 1, 0, 1, 0, 0, 0, 1, 0, 1, 0, 1, 0, 0, 0, 1, 0, 0, 0, 1, 0, 0, 0, 1, 0, 1, 0, 1, 0, 1, 0, 1, 0, 1, 0, 1, 0, 0, 0, 1, 0, 0, 0}

    In this array, there are 95 elements, including zero.
    position 0 = 1st pulse from crank sensor A
    crank sensor B = lags behind A by 7 positions
    position 2 = cyl 1-4 TDC
    position 18 = cam sensor pulse
    position 26 = cyl 2-5 TDC
    position 50 = cyl 7-6 TDC
    position 74 = cyl 3-8 TDC

    Hope this looks accurate, I checked it 3 times before posting.
    I'll bet if we read the eprom in the delteq unit, we will find this data set also.
