Message: [QUOTE="Hotrodtractor, post: 539645, member: 25"] Crash course - the injector fires every 2 revolutions (720 degrees) - it can't physically fire for longer than a 1/4 revolutions (90 degrees) - that means the dead time is 7/4 revolutions for it to refill. You can't have more than one injector ever firing at any given time thanks to the underlying control signals going to the IDM from the PCM (look up the FDCS signal and start reading....) - and even if you could - you don't really want to. The amount of fuel being injected is purely a combination of pulsewidth and ICP - toss on a 200% nozzle and a particular set of injector mods and you can generate a 3D graph like I posted for it and then no matter what combination of PW and ICP you have - you'll know exactly where it falls. Remember when we say its a 238cc injector - that is a 1000 count test - so the injector is actually fired under the test conditions 1000 times to achieve that volume. [/QUOTE]
