The fuel line isn't feeding the reg then the rails.

On the vacuum referenced trucks the regulator sat on the middle of the driver side rail and there was a crossover to the passenger side. Both rails...

You can ask GM the same question. Is the reg before or after the rails on vacuum referenced setups? If he makes the changes let's see what the VE...

Any more explanation on this or better clarification?

Plan to pull a log on the way to work tomorrow morning. Couldn't get the wideband installed this weekend because car developed a misfire and I...

So if I'm understanding this right, when the throttle closes and manifold vacuum increases, and that vacuum pulls up on the reg diaphragm against the...

Having a 2bar os and a 1 bar sensor will not make things any easier. I have to wonder why you are on a 2bar os on an NA build.

We tried starting it in open loop due to the worry that the 02's may be bad since the voltages key on/engine off were so low. It wouldn't fire again....

Welp, update. Checked all the grounds, checked them all through the harness, did a quick check on the harness to see if anything was shorted to...

If you want it to work right the reg goes after the rails for return style. There will be lag deadheading the rails. You will get transient fuel...

No. Keep the vacuum reference feature so that VE tracks correctly. The IFR table doesn't go above 0kPA vac.

In and Out on a regulator is just straight through. The return orifice and return port are tee'd in in the middle. It works the same even if the...

Only on regs that have reversible inlet/outlet.

So, if I remove the Vacuum regulated reference line from the manifold to the FRP, I'll be ok? I would only be running 4-6psi from the turbo.. not...

It has been so long since I looked at a factory regulator that I could not say for sure, but with an aftermarket regulator the pressure will be bled...

You can plumb it like that (reg before) if you aren't using vacuum reference. That's for corvette style regulation. It's adjustable so that it can...

How can language be that... greasy? I want to go take a shower now. On the other hand, your boss probably thinks that sounds like The Future.

Dividing is the same as multiplying by the inverse. 3 / 0.5 is the same as 3 * 2. 1 / 0.5 = 2 That's for if you're doing it like the pic in the...

Kindly remind your brother that while EFI doesn't have a physical accelerator pump, the TPS is still used for things. And if it's already trying to...

I do recall this being one the of way's to plumb in a VR FPR.. Maybe I may have to change things to see if that's what's contributing to the weird VE...

Awesome

Based on the fact that there's an inlet and outlet labeled on the reg. Rail pressure is raised for higher MAP, such as boost or N/A WOT. When the...

This GM PCM Tune File is a must-have piece of automotive history. With a year, make, and model of GM PCM, this unit is a perfect addition to any...

Updated the engine size, I had all the data for the LSA's but we will swap in some FIC's real quick. Map sensor is a stock ls1

Not sure on the 02 voltages, and my brother is pumping the throttle. We could try open loop?

Very odd that it would grab some times, and at other times not. I would have to see a log of it holding to believe it to be honest. As for whyy it...

The sound to some of us is everything even if it is straight piped & stock it will sound straight savage compared to anything you can have welded on...

A disclaimer for other people wanting to try these changes! DO NOT just try to flash this file to your F150 or Raptor. There are OS differences...
