Injector deadtime
One of the UTEC parameters is injector deadtime for larger injectors to operate correctly at low pulse widths. What should I set this to for RC 440 injectors?

Deadtime [ramp up time until flow begins, at 66%, and at 100% flow] are a function of voltage and fuel viscosity [temperature] plus of course PSI.
Use an amplified dc amprobe to view the current ramp up. The current graph will have a tiny ~ when the pintle or disc opens. This will be close but not spot on as some fuel flows before the injector is fully open
Deadtime is a critical idle and cruise parameter.
Assume 0.920 milliseconds to start
