It's not in the government mandated PIDs but can be derived from the OBD data. It's simply "injector pulse width" in msec times RPM divided by 1200.

or DC (%) = [IPW(msec) x RPM] / 1200
Where did you get those numbers for the injector flow rate?

Also, im wondering if the formula you suggested can be put into dashdaq so that it is auotmatically calculated(no sitting there with a calculator for every single rpm)...
