Oops.
I still think you should ditch the GReddy box. A used 12:1 FMU can be had for under $100, a new one woul dbe around $140.

I plan on ditching the GReddy box as soon as I figure out how I want to rigg in the check valve. Its not as easy when the map sensor is atached directly on the throttle body..

hey Inspyral

what is your opinion on the fmax fmu. Do you think that its a good buy???

also, what do they mean when they are talking about 3-bar or 1-bar. Inlighten me......

inspyral

I didn't know FMAX made an FMU.

3 Bar = 43.5psi, 1 Bar = 14.5psi, is that what you're looking for?

jfdmas

fmax fmu is a set up that runs extra injectors that is calibrated by a preprogrammed computer box that reads boost and rpm to adjust fuel curve. They say its good up to 30psi and 16000rpm.

Ohhhhhhh, the MF2. Most people who get the FMAX kits just ditch that, since it's not that great for fuel management. Most of the time you end up with fuel pooling in your charge piping. It's not really an FMU in the sense that a Vortech or other rising rate regulator is. It's an additional injector controller that controls the extra 2 injectors somewhat independently of the rest of the fuel system. Since it's kind of hard to get tuned right, most people either go with simpler forms of fuel management, or go standalone.

thanks,

If you see any fmus cheap let me know.
