Here is some more data from an injector supplier who has worked with Bosch Motorsports.
The data is for 2 different product series, and are tables of injector dead times for pressure versus battery voltage. I am putting this out here for information only - the data shouldn't be used as is, it is just to illustrate some of the discussion points that have been made in this thread regarding fuel injectors and their dead time (or latency or offset).
Discussion points:
1. Higher battery voltage results in shorter dead times.
2. Higher fuel pressure results in longer dead times.
What jumps out at me from this data is that fuel pressure changes (40 to 100 psi) at lower battery voltages (8 V) result in much larger changes in dead time (delta of approx 1.0 ms) than the same fuel pressure changes (40 to 100 psi) at higher battery voltages (16 V) (delta of approx 0.1 ms).
Interesting.
