What I want to do is have 1 12vdc square wave input, with a "splitter" that will alternate between 2 outputs, I want to do this electronically, and not with a Hall type sensor going high or low to reset

QUOTE I'm not exactly sure of what Mueller wants to do or why. I think he wants to run a distributor other than the D-Jet unit, like a Mallory Unilite. I'd looked through your site quite a few times, but don't remember seeing so much data on the ECU before. Looks like only the opening (or is that closing?) of the trigger points is used, so dwell isn't accounted for. Or I completely misread that (which would be easy). Lots of data there. |
