Injector opening delay


I've built a similar gauge for my '99 Nissan Pulsar (which I think is Almera or Altima or something like that in the USA) after being impressed by the MPGuino when it got mentioned on hackaday. My hardware is similar but totally different software.

My question applies to the OpenGauge/MPGuino as well as my thing. Has anyone actually measured the opening and closing delay of a fuel injector? How do we know it's ~500uS? If the opening time is because of the physical movement of the valve, wouldn't there also be a similar closing delay?

Thanks. -Simon
