 large enough that the sequential signals to the injectors aren't in danger of

injector solenoids.  It makes sense to have only one injector spraying at
a time. 

Hello Eric,

Unless you are talking about stationary engines at the state fair, what you 
are suggesting is impossible.  There is simply not enough time to fire the 
injectors without overlap.  Sequential is almost meaningless above 50% duty 
cycle, the intake valves are only open around 35% of the cycle and the 
injectors are spraying up to 85% of the time.  All four cylinders fire in 2 
revolutions, you would need fire hose nozzles to accomplish what you suggest 
at 6000 rpm.
