I have been looking into a blower for my car & most of the mfg's suggest a
FMU (Fuel Management Unit) when I asked specifically how it worked they
said that it is a device that goes in the return line off of your fuel rail.
as Manifold pressure goes up it restricts more. sounds to me like a Back
Pressure regulator that has the sense line going somewhere other than the
input side. most of them are adjustable & the better ones are apparently
pretty linear. this might be an accurate way to do what you are trying to
do. I talked with techs @ Paxton, ATI, & Vortech & they all have the "same"
thing. there are a ton of them on the fox bodied rustangs here in Southern
California & I guess they serve their purpose. I would be willing to be
that a bunch of the turbo guys have them as well.

Subject: Rising rate fuel pressure regulator
Scott Flanagan mentioned he was trying to map out a rising rate fuel
pressure regulator.
I am also looking for a rising rate regulator that reacts to turbo boost.
All the turbo fuel pressure regulators I have seen, raise fuel pressure at
a rate equal to the amount of boost.
I would like to find a fuel pressure regulator that gives something like 2
: 1 to give around 75 / 90 psi at 20 psi boost.
The aim is to bypass the need to fit larger injectors when increasing the
power output of the engine and also the standard injectors will allow the
car to idle better.
I also want to fit a fuel pressure sensor linked into the ECU to keep an
eye on fuel pressure.
