FMU's

[ultimatuc]

are any of you running FMU's?

From what I understand, they work as a rising rate FPR. Instead of just creating more fuel pressure w/ a vacuum loss, these will actually close off all, or most fuel return when it senses boost.

depending on what my a/f ratio looks like next time I dyno, I may give one of these a shot.

thoughts?

No fuel management < disc type FMU < BEGI FPR < piggyback systems < ROM tune < full standalone

It's only valuable when you have stock injectors and are running less than 6psi with no other fuel management. I wouldn't use it to supplement larger injectors because it would overcompensate.

I am building a BASIC basic setup...I was thinking of a FMU and 370ccs off the SR..?bad thinking?

fmu and sr 370's is over kill for a basic setup. if you get the bigger injectors then you will need somethign to control them. i was running an fmu at 9psi for months and it ran great that was an 8:1 begi fmu
