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

yes to a bunch of the questions (IMG:style_emoticons/default/smile.gif)
trying to eliminate the trigger points in the base of the distributor for the D-Jet with the L-Jet, all 4 injectors fire when the coil collapses, with the D-Jet, there is a cam lobe on the dizzy shaft that in normally open, right before the intake opens, the contacts touch, sending a small 12vdc signal to the ECU, the ECU then grounds the injectors firing one pair (every ignition cycle one or the other contact closes completing the loop)....very small amperage amount from what I have read, less than the contact points driving the coil. not sure if the ECU cares about dwell or not, it could be as simple as on/off, same as the L-Jet, as long as there is a voltage differantial, the trigger works |
