Megasquirt question regarding injector grouping

Hi guys I was wondering how I should group my injectors to my megasquirt1v3... John Allen seems to have them grouped as 1+4 and 2+3. Is there a reason for this? Does it matter? The reason I ask is because the megasquirt diagram has the injector ground signals wired in the same pairs as the injector power wires (the ones that share a fuse)...and John's method would seem to differ from that...if anyone has helpful info please chime in!

I am still working on my Megasquirt and have staged the injectors the same way. Just realize that the breaking up only reduces the surging in the fuel rail to give more optium pressure to each injector.

The injectors fire even when the valves are closed and allow the fuel to mix with the air in the runner. So, it really should not matter if you stage 1-4, 2-3 or 1-2, 3-4.
