Pulse Width?

[BoostedOreo]

Just wondering if anyone off hand knows the pulse width in mS for Rc 550cc injectors being open?

It will vary from 0 to 20+ milliseconds. And the duty cycle will vary from 0-100%. Entirely depends on the ECU, it determines pulsewidth(based on airflow and other factors), not the injectors. Rephrase the question. What are you trying to find out, or what are you trying to do?

i actually got the info i needed. but what i was doing was trying to figure out the duty cycle for my injectors were at wot. found out that at about 7000rpms its at close to 90% duty cycle. time for an upgrade.

How did you get the info you needed? Asking anyone is the wrong way to get that info, the only way to get the info, is to actually datalog your car, and find out your pulsewidth, duty cycles etc, because this is going to vary from car to car based on your complete setup.

my friend found a site that had a layout of all the pulsewidths through all the rpms. we datalogged it too, thats how i know im running out of injector.
