I bet it will work just fine batch firing both of your injectors four time per engine cycle given that they are shooting into different planes, but I totally understand your desire to make it 'theoretically' better! I'm doing a bunch of minor modifications to my system right now that I doubt will change much, but should look a little 'cleaner'. If you decide to pick up a Megasquirt ECU it can definitely alternate injector firing between the two circuits. I had mine set up that way at first but it didn't work well due to my single plane manifold I think, with one injector closer to the rear cylinders and one closer to the front. Can you use a WB O2 input into the GM ECM?
