dfink,
I'm not sure what you mean by 5 shots of fuel followed by the last and final 6th shot?
My understanding of this system is that it injects 2 shots to EACH injectors per complete power stroke. Meaning 1 shot of fuel for each turn of the crank and all injectors get fired at the same exact time. I also am under the understanding that the fuel delivery timing is fired off of the Top-Dead-Center sensor on the crank. So one shot of fuel every time the crank hits the TDC sensor mark.
This design allows each injector to deliver exactly 1/2 the fuel volume each time the injector fires. This is because the injectors fire 2 times per power stroke.
This is simply my understanding of the Motronic system. I could be wrong, but from everything I've read this is how the system works.
Could you clarify what you mean by 6 shots of fuel? Are you speaking about all injectors? and counting each injector individually?
