    On second thought, it looks like this probably would not be adaptable for a 13.5V system. You would have to run 18.5V to compensate for the voltage drop, and would need 10-15A diodes to get enough...

    Hmm. Perhaps it was time for the 30yr old logic pulser to die. One too many abuses over time. Probably kickback voltage along the ground path. I wish I had more time these days. Don't know how...

    Well, with the 1x cam output, one could mount or buy a 24x crank reluctor while using a 0411 pcm. As years go by, and 2007-up pcms get hacked, one will probably want to switch to the 58x (60-2)...
