Web13 dec. 2024 · “Making sure that injector pulse-width commanded is more than the minimum pulse width at low load (normally idle) is important,” adds Lunsford. “Huge injectors for a combo normally can be a challenge to idle at low RPM.” If you feel a larger injector is needed, determining the proper injector size for an engine is a rather easy … WebThe "Fuel load" to "pulse width calculation" uses many factors like engine displacement, fuel type and injector flow. The injector dead time is also added to the pulse width calculation. All of these are pretty much constants so the "fuel load" to "pulse width" relationship is almost linear.
