Remove the factory clock and mount it there.

Mousier158

Mousier158

I have one but I can't help ya sorry my Zs not turboed yet

Damn,...I didn't read that at all.

Sorry, no help here. Haven't driven mine enough to get the settings right.

i'm running 47% set Gain 35% and SET GAIN is 17.5 waraning is 21.5 limiter is 15%. You do have the pontental to run 20psi on stock tt engine but not recomended. I'm running 16.5 psi on mine. I love the profec B Spec is great.

should've gotten an Apex-i AVC/R if you ask me... set the boost level and leave it alone, let it figure its own duty cycle out... can't beat self learning electronics =D

MadZ420

Ya I do like those but my purchase was spur of the moment. But I do like the control I have with the B spec.

I was unaware the Apexi unit was self-learning. However, i am very plaesed with the ProfecB!!

That apexi AVC/R uses fuzzy logic to making it "self learning"... It is NOT recommended to use Fuzzy logic boost controllers with turbo turbo setups that are in parrellel.

Has anyone had any problems with the Greddy profec B.. I have heard that the stepping motors go on them and that is a problem with that boost controller... Has anyone ever had this problem?

MadZ420

Wasn't aware of any motors in the controler. I thaought it was all electronic, with the vacum selonoid. But not a single problem with mine, I love it.

are you running stock turbos? and if so how much boost can you run on stock turbos and injectors?

MadZ420

Um.. I have ran 20 lbs. but Safely I like to keep it about 13-15. Yes stock engine, all of it. I also use the water/alcohol injection witch lowers intake charge temps. The alcohol makes up for the leaness that may happen with stock injectors pushing over 16 lbs. I only use the water/alcohol system over 15 lbs.

Awesome.. I hope to pick one of these up soon (Greddy Profec B spec 2)

I have one and it works great...It really holds the boost right where you want!

1SIKZ

murder.. apporximately how long does it take to install and do i have to buy amything else to install it or does it come with everything you need?

Mousier158

the kit dosent come with near enough vaccum hose. deffinately buy more hose! you'll need some "T" connectors to tap into existing vaccum lines. how many and what lengthof hose is dependant on how you plan to route the unit.

1SIKZ

quick question.. where exactly do i tap this into. and do i need to do it twice or?? on a twin turbo setup like the Z im confused as to how you would go about doing that

Mousier158

I forgot to mention you also need to buy hose caps size 4mm and 6mm.

Esentially you are bypassing the stock boost selenoids. you have to tap into the waste gate hose, intake hose, and fuel pressure regulator hose (remember everything x2). As i was saying before, it really depends what set up you want and how you are routing the lines. In the kit there's an instruction manual that will give you the generic idea, but because we are TT'd it's a little more difficult...less straight forward on set-up. Hope this helps.

1SIKZ

HAHAHAH you got any picture when you installed yours or do you know where a good write up is.. thanks

Mousier158

here's from the instruction manual. one from the way i routed it. see the "T" at the rear of the engine. that is where i brought the lines from the waste gate to one line that routes to selenoid actuator. then the "T" on the fuel pressure line which goes to the unit in the cockpit.

Shameless

Im in the same boat im working on installing mine right now and im slightly confused on how its actually supposed to work with our set up.

I already went and purchased more vacuum line but im confused on how the setup actually is supposed to go together. The kit comes with one Y connector would it be possible to run both vaccum lines from the actuator's to the y and then one line into the controller. LOL that diagram they give doesnt help us very much.


Hold on lol let me see if im understanding this better.

I have to run a hose from both of the actuator's run them into a Y or T and then one line into Which side of the Controller (no or com)

I also have to run a hose from each of the Turbo's compresser side pipes going to the intercoolers. I have to plug them into a T or a Y and then run them into one side of the Controller (no or com)

And i also have to run the smaller hose from the Cooled pipes leaving the intercooler and run them into a T or Y and then into the Unit inside the car?

My brain hurts.......

HERE IS HOW I INSTALLED IT!!.. LOOKS SIK EH
