[QUOTE="Hotrodtractor, post: 37311, member: 25"] At 4000RPMs you have 24 crankshaft degrees of rotation every millisecond - the FDCS signal that controls the IDM to fire the injectors becomes unstable if it is operating above say a 70% duty cycle (for a safe number) - that puts the maximum window at about 63* of crankshaft rotation - or about 2.62ms of PW. Some tuning strategies - including my own - put the target injection window much tighter than the 63* maximum. I was going to include some nice math here to show you fuel rate for the pump required based on the available injector refill time and actual numbers - but.... my math isn't working out on paper and I don't have time at the moment to figure out what I screwed up.
