Does anyone know what size injectors we have?
45.8 #/hr (or 480 cc/min) @ 43.5 psi
This is 52 #/hr @ 56 psi (stock regulator pressure)
How do you measure duty cycle on a datalogger?
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
