running out of fuel

[shtboxyj]

first turbo build.
6.0L 228/230 cam.
gt45 turbo
525 in tank
sep1000
boost referenced regulator
fuel pressure doesnt drop at regulator or rail.
but in the same ve cell it will go pig rich to dead lean,
fuel pressure raises with boost but it acts like im running out.
base about 58.
what am i missing?

yes everything is a wreck. just got it going. but cant really do much till i figure this out.

Do you have a wideband on that thing? Under fuel--your VAC table is not set up for boost referenced. The 0 row should be the same all the way across---IF it is correct for those injectors. Your timing is down in the 1 degree range, something is causing it to drop. Your Hot PE enable is set to 90%. Make that something like 40% so it will kick on. You have it limited to 80kpa anyway. PE chart is 1.17, make that 1.25 until you get it running good. What spark plugs are you running? Ive got a feeling it is running wayyy lean. Your injector duty is only 26%.

yes there is a wideband but i only hve it set in the chart layout.
my hot select is high so it wont use that table.
its rich as soon as it sees commanded but will quickly run lean. even out of boost.
i dont want to start pulling from ve until i can figure out why its doing it.

also they are 1000cc injectors.

this what you are talking about?
with a referenced regulator shouldnt it be flat like this?

Offset vs Volts vs VAC chart.
What your wideband is telling me is that at 4000 rpm, your ve table is lean. You can see it go from rich to lean as the rpm increases. I think as you work on it, the shape of your table is going to change.
I think that I saw your PE was delayed 2000 rpm---maybe somebody else---but if that is correct, make the delay 0.

Here is what I meant about shape. This probably won't help much, but it might a little. One is a turbo tune and one is my roots blower tune--VE tables. Shapes are similar.

your file is not setup right

if you look at the pictures it is in the same cell of the ve table. this was 3rd gear footbrake. so the rpms are not increasing. it in the same cell and goes rich to lean.

That's typically caused by incorrect injector data, or a fuel system that isn't keeping up.

[shtboxyj]

that is what was supplied with injectors.
mas tuning i tried those changes and no difference.
i would think if i was running out of fuel at the rail i would see a drop in pressure at rail.
im hard pressed to believe id have low flow but maintain pressure. if im wrong please correct me.

[shtboxyj]

i installed aftermarket rail. so feed goes to rail-crossover-rail-regulator. still same problem.

[shtboxyj]

any other ideas anyone?

[shtboxyj]

figured it out. it was a bad wideband sensor. logged and watched narrow bands and they stayed rich. thank you for your input.
