Injector wiring has very little effect on how the engine runs, this is a batch fire system.I have tried 2 setups 1,3,5,7 on channel 1 and 2,4,6,8 on channel 2 and there was no noticable difference between 1,4,6,7 ch1 and 8,3,5,2 ch2.
Although I never noticed any difference in the engine, I continue to use setup #2 , this setup uses 2 cylinders from each bank on channel 1 and the same for channel 2,only because this should reduce the possibility of fuel pressure pulsations.
