I know it has been discussed so many times in different forums, and I am not here to bring it up to waste time for no apparent reason but what exactly is the main purpose of the two. I heard from old timers saying that a batch fire system will increase the latency(dead-time, since the injector isn't held open throughout the two revolutions and closed, but it's opening, spraing, closing, opening, spraying, closing in two revolutions, fired twice that is in a 4 stroke..which makes sense) in the injectors at idle on normal cars.

Now on high a horsepower cars at idle ... is it a requirement to run larger injectors to reduce duty cycle and increase the pulsewidth limit ? Does this have something to do with a commanded set time drop in latency also because you are spreading out the pulsewidth limit which will reduce duty cycle then? Correct me if Im wrong.

So if you had 2x the dead time on an injector for a Batch fire system vs a Sequential one, you pretty much have to force yourself to increase the injector size for a batch system in order to reduce the duty cycle, which will give you a shorter latency ? I thought latency was a set value each injector had that regulated from battery voltage.

Why ? He had no explanation either, somebody correct me.
