So yeah we are pretty much agreeing hten haha.
I just have no hard evidence one way or another that usiing a higher fuel pressure increases atomization, or how youd even test that in real world conditions.
You say our injectors arent suited to that pressure, where did you get that information? It seems like the info Tom got is contradictory (not to say whos right or wrong, just trying to figure it out.) The manufacturer of the injectors we put in the Audi rated their flow at 3 bar, to be standard, but told us that running them at 4 bar would be no problem.
Anyway, I love running open loop all the time. Ive never gotten better fuel mileage and performance. I was able to lean my car way out at part throttle, which I wouldnt have been able to do closed loop. Part throttle tuning almost requires the use of open loop, if not at least narrowing the closed loop operation to idle and very light throttle, and at that point I dont see the reason to have it around anyway.
Do you know the answer to my boost reference question? like the stock fuel pressure goes from just above 2 bar at idle up to 3 bar at WOT, does it keep going higher in boost?
