Yes, but the speed injectors open and close on engine is too slow that impedance can have any influence.
Maybe at 5 kHZ you will notice a difference, but since engine runs to about 50-60hz that is waaaay to slow
Yes and no, injector latency is measured in milliseconds, and the rise time (and thus opening time) is directly related to impedance, and how well the drivers are matched to supplying current quickly enough during opening...
I could be wrong, though, perhaps in this region of operation it doesn't matter. I suspect that it does alter latency though.
