Just as a side note, let's not confuse 'Pulsewidth' with 'Duty Cycle'.

Pulsewidth is injector 'on' TIME each time it is cycled.

Duty cycle is the ratio of 'on' time divided by 'on+off' time.

I'm just doing this to clarify because its easy to glaze over.

And I agree with Tom Cloud, we'd see duty cycle on an analog meter.
Sounds 
interesting.
