Message: [QUOTE="Charles, post: 613691, member: 103"] Explain why you would want to alter the timing of the injection event based on the travel the plunger [i]might[/i] cycle through 2ms later? Lets say you're driving along at .9ms of pw with a 200% EDM. NEITHER injector is even CLOSE to full stroke.... so tell me why you would have the 400cc injector doing anything different? Say you roll on the power and start pulling hard, lets say 1.6ms. Neither injector is full stroke still.... Now lets say you ask for some duration above the point where the 200cc injector goes full stroke, say 2.5ms. What changes??? The 200cc injector simply hits bottom stroke and no more fuel is injected, and the 400cc injector keeps on injecting. Now if you add timing to the 400cc injector, pick up power and still come in under your target cylinder pressure then you should have been running that SAME TIMING on the 200cc injector in the first place!!! LOL The only exception here would be drowning the cylinder with fuel (think mod class puller here) where excessive timing can be run since the mixture will not likely flash off quickly since there is always unburned fuel to soften the burn. In a case like that a lower injection quantity might not keep the combustion "soft" enough, and you'd want to lighten off the timing accordingly. Why??? They both inject fuel at exactly the same time, in the same way, with the same patterns, droplet sizes, so on and so forth. [/QUOTE]
