FMU-Fuel management unit
technical name Rising rate fuel pressure regulator as the manifold pressure increases, the FMU increases the fuel pressure by a calibrated ratio. the FMU i have in my turbo setup is a 12:1, 12psi more fuel for every 1 psi of boost. right now im running really really rich. gotta lean it out for more power and better mpg, although 22mpg isnt bad. and if your friends eclipse is already a turbo, you dont need the fmu.
