Right now i have a 12:1 fmu and a walbro 255 hp in the tank and i am wondering if i have too much fuel going into the motor. My setup is a stock d15b7 with a TD04L. At about 3-3.5k it will sometimes bog/hesitate alittle and not wanna go any higher, RPM wise. Cuz other times its fine and doesn't do it at all especially in 1st gear. Could this be too much fuel?

its the fmu... period.

Um okay that helps...are you saying a lower ratio disk would be better or no FMU at all??

Ravage70

hes saying sell that pos and use real management

92chb

Well i really dont have the money for "real" managment. This is temporary tilli save up some money. So for what i have now what can i do to get rid of the problem?

hotrex

nothing. a fmu is untunable, its a piece of ---- and maybe your car will blow up with any luck... post pics of the destruction

So all of you are saying since i dont have real fuel managment no FMU is better than having one?

Ravage70

no
were saying ur stuck with shitty results because ur using a shitty solution

FooK

do what johnny does, air pressure regulator (from an air compressor) between fmu and signal line, control how much pressure the FMU sees.

turboDA6

they all pretty much nailed it... its a piece of ----... straight up... if u can't afford real management. why are you turbo? a new motor is gonna cost more then real management. funny thing is a chipped ecu for ur setup cost as much as an fmu...
