    Looks SWEET!!!

    Where does one find these elusive bin, ADX and XDF files? Are the VSS and the MAF the only pins changed/added?

    I have always set my base timing to 10 or 12 degrees because the AMC motor idles better there. I had trouble keeping it idling at zero.

    I have 5 or 6 extras. By the time I go through them (if I ever do), I'll probably be swapping in an OBD II system with flash reprogramming, anyway. I'm not too worried.

    Someone used to sell them, but they were pricey. I've just drilled larger holes in them to adjust. I remember breaking through one of the holes, but it held really tight even with just one hole.
