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

Now that I think about it, the two trigger points have one lobe, the ignition points have 4. So to youse a tach signal, you not only need to flip flop between two outputs, but you aslo need to divide by two. Also, aren't the trigger points set up such that the injector opens when its intake valve is open? I think that would be impossible to get out of a tach signal.. if you could get that, it'd almost certainly involve a dead cat. (IMG:style_emoticons/default/smile.gif)
