Vac/Boost referenced Fuel pressure: What pressure for FP

[ajpturbopittsburgh]

I have a return fuel system set at 60 psi while idling with a boost/vac line hooked up to the fuel pressure regulator. It's a 1:1 regulator.

I have 60 psi entered in flash pro for current fuel pressure. But do I want to unhook the vac line and see what the fuel pressure is and enter THAT number? I figure If I unhook it fuel pressure will change at idle.

Also I have precision 650cc injectors. I'm fine tuning and trying to dial in things a bit better. My car was tuned awhile ago and runs pretty well but I know the tuner never messed with dead times. At idle every so often I get hiccups and wild afr swings. But my STFT's look pretty good

I don't know how to do screen shots. Here is my injector data.

6v 8v 10v 12v 16v
3162 2116 1450 1092 684


I can't find any injector data online.

I use sct for Ford tuning and understand injector data is very important as far as slope and breakpoints which are absent on flashpro...I'm guessing it's not required like it is in SCT. I have an 08 civic SI btw

Going from stock to a manifold compensated fuel pressure regulator is going to skew the fuel tables slightly. I'd use the fuel pressure with the vacuum line disconnected, so more like 70 psi.

The dead times look a little low. You can normally tell by seeing what the short term trim does on a very slowly reducing throttle. When the dead times are too low the STT will go up just before injector cutoff.
