Question on direct injection fuel system.

[Crazy AWD]

My car has a high pressure direct injection fuel system that can actually inject up to three times per combustion cycle (something about getting the optimal fuel mixture in the cylinder). Will the 0-3 injections per cycle affect the IDC function? Or is it still just a matter of injection/time? Would I be better off tapping one of the ignition coil negative triggers instead?

Tahnks!
