turbo d16y7 running like crap

[95turbodel]

hi im running a d16y7 in a 95 civic ex with a t3 turbo, ac autotechnic fuel rail, fmu, and a fuel pump. it bogs out at 4500 to 5000 rpm tryed a 94 lx ecu and it does the samething tryed a p28 ecu samething. what do u think it is?

Most likely the FMU is making it too rich. Do you have a Wideband O2? That would tell you right away.

ditch the fmu and get tuned.

I dont have a wide band o2 and where do i find one.

Any shop that actually tunes with a dyno should have one.

FMU can cause your injectors to leak whick makes your car bog down cause its too rich.

That's only part of it... and they'll only cause your injectors to leak if you're overpressuring them.

Most of the time you really just need a good tune, that's all. Timing is key.

nothing compared to a real tune.

Doesn't a FMU constantly over pressure the injectors when you are in boost? All I know is shortly after boosting with the FMU in my car the car would bog at low RPMs or when I hit the throttle and I could smell excess fuel because of the injectors leaking.

Yes, it does overpressure while in boost- that's how they work. They're generally not bad for low boost setups that don't make too much power because you're not overstressing the injectors, but for anything with real power expectations, using a RRFPR or FMU is just a bad idea.
