REQ_FUEL value is the amount of fuel (in milliseconds) required for a MAP reading of 100Kpa, manifold air temp of 70 degrees F, and a barometer of 30.00 In Hg, for one complete filling of one cylinder (Volumetric Efficiency = 100%), without any enrichments.

Highest rpm, lowest map reading.

However, sequential injection does not necessarily mean you are injecting into an open intake valve all the time. The intake valve is only open less than 30% of the time in a typical 4 stroke engine.

Once you are trying to produce more than about 25% of maximum HP your injectors are firing for longer than the intake valves are open. If your maximum HP is correctly calibrated to a safe 80% duty cycle, your injectors are injecting well over 50% of the time on closed valves.

At higher rpms, it becomes increasingly difficult to inject while the valve is open. For example, if your Req_Fuel = 15.0 ms, and your maximum duty cycle is 85% then the interval between injections cannot be closer than 17.6 ms.
