Question about Injector dead time

[acca]

Hello

I'm using an injector ref 96620255 for a prototype 4 strokes monocylinder vehicule.

I did not find infos about this injector's dead time comp.

I'd like to determine by the following method :
- Power my M84 ECU with a stabilized power supply set to 10v (for example)
- Put the injector nozzle in a glass bottle
- use the "utilities/test output" in ECU manager to test my injector at a given Pulse Width
- reduce the Pulse width till the injector injects gasoline
- The minimum pulse width that allows gasoline to be injected corresponds to the injector dead time
Start again at 12v ...

Is my dead time measurement method right ?
Thanks
