Been a long time since I have posted here.
I'm calling out to all the tuners out there.
My question is when is the best time to inject fuel?
I'm well aware that fuel needs to be injected into an open intake valve on the intake stroke (yes, the intake can only be open on the intake stroke) however I would like some real opinions and feedback from those in the know on:-
1) How far after the intake valves open (in degrees) should the injectors start delivering fuel?
2) If there is a range of degrees that should be used so as not to run out of time. In other words if the injector on time is longer than the valve openning, how is this managed.
3) Are there any considerations for different fuel types etc.. (for instance E85 takes longer to burn and usually needs more fuel / potentially longer injector on time).
4) Anything else?
