Yea I had to draw it out for injector timing, but it works ok once you understand the reference point. By default it is at 540*, or 0* for them. The intake valve closes ~60* after. It isn't the worst, but idle sucks. The biggest head scratcher is if you enable their injector timing table it is MAP vs RPM. What MAP has to do with injector timing I have no idea lol. You can make a custom 3d table that inj PW vs rpm vs injector end angle offset and then you actually have something useful.
What strategy did you use for your engine? We have very similar valve events.
At idle/low RPM I'm targeting to advance the fuel spray as much as possible, starting just at or slightly before the exhaust valve closes as the fuel takes some time to reach the chamber.
As load increases, retarding the spray timing to get the bulk of the fuel sprayed into an open intake valve and during high piston velocity. Obviously at longer duty cycles and higher rpm injector timing matters much less as the injectors will just be on for most of the time.
I'm not sure what my duty cycle is going to be yet. I'm guessing ~60% on 91 octane and ~80% on E85.
I've done this strategy before with a slightly smaller cam on the GM ecu and actually found spraying on a closed intake valve like GM's approach to be easier to tune at low speed and take less fuel. When I actually get to tuning this thing I plan to swing injector timing forward and back in some pretty big swings and see what it likes at low load.
