Jerry, The ECM I am using came off a port injected, speed density, non sequential system. All the injectors fire at the same time. My injectors will be in the throttle bodies. Two injectors per throttle body. (4 total) Although it is not a factor on my application I think a sequential system would work with 2 injectors per runner.(6) If the injector pulses are timed correctly the fuel would be drawn into the proper cylinder since they fire at different times. This is all speculation on my part based on my experience with fuel injection.
