What is a turbo FMU?
SPA Turbo Composite 14:1 FMU Up to 14:1 adjustable gain rate FMU = fuel management unit SPA composite Fuel Management Unit Lightweight and virtually in-destructible. If you increase the boost referenced ratio to 14:1, your fuel pressure will increase by 140 psi.
What does an FMU do?
The FMU is essentially a variable fuel-pressure regulator that automatically raises fuel pressure as boost rises. Higher fuel rail pressure enables the fuel injectors to deliver more fuel in the same amount of time than they do at the static stock fuel pressure.
What is a FMU on a car?
The Vortech Standard Fuel Management Unit (FMU) is designed for use on multi-point electronic fuel injected engines. It is a secondary fuel regulator that installs in series with a stock regulator on the return line to the tank.
How much HP does a turbo Civic make?
There are several powertrains available for this Honda. Sedan and coupes come standard with a 2.0-liter four-cylinder engine that makes 158 horsepower. Two 1.5-liter turbocharged four-cylinder engines are available. One puts out 174 horsepower, while the turbo-four in the high-end Civic Si produces 205 horsepower.
What is a rising rate fuel pressure regulator?
If the fuel pressure regulator (aftermarket or OEM) is connected with a vacuum hose to the intake manifold, then regulator is a 1:1 rising rate. This means that fuel pressure increases with boost and decreases with vacuum at a 1:1 ratio. However, the fuel rail pressure is not necessarily what the pump is seeing.
What is a Rrfpr?
people ran RRFPR, rising rate fuel pressure regulators. Essentially this little dongle will be installed after the factory (or aftermarket) fuel pressure regulator and restrict fuel from flowing through in increments according to the amount of boost it sees.
What is a FMU fuel management unit?
What is an FMU? A fuel management unit is a fuel pressure regulator. The FMU works on fuel injected, supercharged engines using the factory electronic engine management system. When an engine is supercharged, the air delivered to it is greatly increased.
Does a fuel pressure regulator increase horsepower?
The noob belief amongst amateur tuners is increasing the fuel pressure up a few psi from the regulator will mean the injectors are getting moaar fuel which will increase the horsepower. Wrong. Truth be told, aftermarket FPRs are not necessary and the factory OEM FPR will do the job just fine.
