Thx everyone.

What my 2 options are is using the factory vr sensor and location with standalone edis. In which  would need a custom sprocket made that would fit behind the dust cover. Versus a stock ford sprocket, custom bracket, and VR sensor mounted out on the crank.pully. This is the easist option but I dont know how sensative it would be on muddy trails. I can always fab a mud guard along the bottom to protect the crank area. TIA

Most injection systems are batch fire, even if it is a sequential system, at
freeway RPM, the system has to pulse the injectors without regard to the
intake valve opening timing just to meter the correct amount of fuel to run
right.

Not usually, batch fire is used during fuel enrichment like the choke on a carb but otherwise sequential injection is used. Even at higher RPM and load the injectors are always fired timed to the valve opening. It is true that on a production vehicle the injector is fired with the valve closed for optimum emisisons performance. On a performance vehicle its fired slightly before the valve opens, the timing makes a noticable difference. MS used to claim that there was no difference but their hardware didn't support sequential injection.
