Well I did learn more about Mopar electronic ignition. Mostly what I learned is the modern 4 pin ecu's like a good working, charging/electrical system pumping out 12.5 to 13.5 vdc. The old 5 piners maybe can survive with much less voltage (I was using just a well charged battery during testing). But the Chinese specials ain't happening. The re-wire of the car interrupted my fun with ecu's game. As soon as I wired in the alternator and voltage regulator, starter relay etc. all the issues disappeared. Tried a couple 4 pinners and car likes them now. Lesson learned.
Props to
@67Dart273. As usual I think he was on the right track:
"It also might be that due to the Chineseoizationized aftermarket, the "new" 4 pin need a bit more trigger power."
