IF I recall correctly the ecu sends a pulse to the injection pump which determines time + duration.

The only issue that I can foresee is that there are actually 2 injection events for every pulse. 1) Pilot event; low flow finer mist. On my car this occours (pop) when the injection pump reaches 224-229 bar and 2)the primary injection event at 307-309 Bar.

I am concerned about the different flow rates per unit time messing up the calculations. AKA at Idle the Pilot injection could be 50% of the injector open time and at WOT it might be 5% of the time.

And at higher RPM the pump is flowing more fuel therefore it will also affect the length of injection events versus time open. (Understand my concern?)




NOTE: 2004 + CARS WILL BE ENTIRELY DIFFERENT THAN MINE. They used Unit injectors.
