few problems, bov, tru boost,turbotimer

[malcantry]

Yeah, i just installed the alteredcustoms fmic and i had multiple problems actually..

I work with engines and piping, metalwork and whatnot for a living and this job is no problem, or so i thought.

The fmic sits low after i put the bumper back on, i mounted it below the actual frame, has there been success of in front? how would you mount it otherwise?

Secondly, the [coupler] piping straight off the turbo is a reducing 90degr. to an enlarged 2 1/2"? well, this is harshly riding on the o2 sensor and i cannot reposition too much..

then, whats the real deal with that @$#%*&$@%&!#%$& MAF? i hate it. is it necessary? I thought the BOV was supposed to be on the cold side.. can i remove the maf and put the bov there? i could prolly make the piping around the o2 work better if the stupid 6" w/flange and bov wasnt there. I EVEN HAD TO REMOVE THE PASSENGER SIDE RADIATOR FAN! lol.. good thing its winter and ill hopefully be resolving this in the next 2 months.

and another thing! im getting a turkey. mad turkey. i have heard some say its a rush through the fmic because i hear it when im not even in the turbo (for sure! like 2000rpm) i have a greddy RS and have adjusted it thoroughly, currently i have it almost completely open, loose. At a higher gear in higher acceleration ill hear a swoosh, but its always accompanied by an echo... what you think? I have also replaced the vac lines from the bov, wastegate and to T'd to the intake.. Only thing is the intake 90degr. hasnt been changed and i am really skeptical about it now.. :X

OK this is getting long..

I also have an AEM Tru Boost and a little confused, is the only vac hose coming off the entire turbo from the wastegate actuator? I dont get that shiz, is our wastegate adjustable? Do i have to get a new one? how in the world do i see the boost and then be able to adjust it? Fill me in!

is a MAF necessary? yes. yes it is. unless you want to pony up mad dollars to switch to a MAP and standalone EMS.
the altered customs kit lets you relocate the MAF from the intake to the cold pipe between the throttle body and the BOV. if you haven't moved it, it could be related to your issues, but since i don't have one i really can't comment beyond that.
the BOV is supposed to be on the cold side, so thats good. it should also be T'd to the brake boost line, i'm a little confused as to where it runs right now.

I got the maf close to the throttle i belive that is what you mean by the cold side. my bypass (bov) is at the hot side pretty far away from the maf so the release of pressure dont afect the readings. as as your turkey goes may be your bov tension is to loose and the seal is flutering? but the turkey is usaly echo I thought?
I cut my waste gate bar and made it shorter and tighter I run 8psi steady but that is as high is stock will go with out a bcv

You want your MAF as close to the throttle body as possible.

Then put your BOV as far away from the MAF as possible, but make sure it's still on the cold side.

This will help with turkey.

It should go in this order Throttle Body --> MAF --> BOV.

Wait are you running 8psi on the stock ecu?

 

[pavone]

from my understanding maf at least 6 inches away from throttle body, then at least another 6 inches away from the maf you can put your bov, however cold side or hot side is debatable. as long as its on the pressure side of things youll be alright. people like getting rid of the hot air rather than the cooled air.

as far as the fmic mounting, which kit did you get? the bigger cores on her site stick down a little bit.

also having a dedicated vacuum line off the brake booster might help with turkey. the source of the intake manifold isnt too strong and might not be opening up the bov as quickly as it should.

I would not put the BOV on the hot pipe....unless you want to release hot air into your engine bay.

 

[CHIQLES]

yes im running on stock ecu no problem but doit at your own risk as they say. im getting my wideband soon so I can moniter the a/f.

I would not put the BOV on the hot pipe....unless you want to release hot air into your engine bay.

your more than welcome to run it through the intercooler, but people put it there so the hot air is released and the colder air remains inside the piping, so as soon as you get on it, cold air is still there, hot air in your engine bay while driving at 100 km/h is not gonna do a whole lot of damage, now if you sit there blowin off in parking lot...yea it may get hot...till you move lol
