Fmu?

I give up, what is this thing?

I keep seeing FMU used all over the place, but I was obviously sleeping when they told me what it was. So after you finish laughing at me, please tell me what the heck it is.

FMU stands for fuel management unit. It is used on boosted applications such as a supercharger or turbo. It raises fuel pressure based on manifold pressure.

Boost goes up, fuel pressure goes up adding the required extra fuel.

Thanks, I was guessing that's what it was but just wasn't sure. Now I just have to do the research to find out which one I will need. I'm trying to round up all the components for a twin turbo setup, hopefully I'll have it finished by March. Wish me luck, cause as you can see... I'm gonna need it.
