Ok, just to prove that the pulsin idea does work.........(within certain parameters anyways, I know it takes a finite amount of time for an injector to open and close and this amount would have to be accounted for in final calculations, and I also know that fuel rail pressure, system voltage, and injector/fuel temperature also have an effect on open/close times. I never said this method would be 100% accurate, but I'm sure the results can be tweaked thru software to get something fairly accurate.)

Do you have working hardware? In other words, do you have an input wire that could be or is connected directly to a PIC input pin? And if you connected an o'scope to that pin/wire, would the resultant signal on the 'scope follow/match the signal on the wire to the injector?

Without working hardware, further discussion would be fruitless...
So if you're just talking in theory, an idea you have...say so now so I (others?) don't use up too much time on this.
