okay... I have run all the searches and found all the sites with how-to's for doing this, but the steps seem fuzzy. I tried following the ENGLISH greddy instructions but it comes with 6 or so different ways to hook it up and I don't know which one I need to use. So if anyone can give/get me good step by step instructions I would be greatly appeciative.

 

I used this from the Scuderia site

PRofec B installation:

Remove air box and intake piping so you can access the waste gate.


remove the 4 inch piece of hose going from the turbo to the wastegate. This tubing contains the pill which you dont need now.


mount the stepper motor or little black box somewhere around the headlight under the hood.


run a piece of hose from the turbo to the "IN" on the black box, then from the "OUT" to the waste gate. It just acts as a bridge between the two. Then reinstall the air box and intake hoses.


run the power cable coming from the black box inside the car near the drivers side kick panel. I took it through the steering wheel boot or follow through where your boost gauge hose goes into the cockpit.


Mount the the Profec B somewhere where you can access the dials on it. I velcrowed it to the kick panel to the left of the clutch.


Now take the vaccum tubing for the boost gauge and cut it near the back of the Profec and add a T connector. Take a small piece of tubing and go from the T connector to the back of the Profec B.


Find where you want to add the power to the Profec B and there ya have it. Make sure to keep the settings all the way down at first. That would be the LOW setting. then play with it and have fun.

Except I forgot to turn the settings down!
It's really simple, just ignore most of that.

 

When you tune your Low boost and High boost settins keep this in mind.........The low boost increments are not the same as the high boost increments on the dial. IE(if your low boost dial is at 12 o'clock and you have 10PSI , Your high boost dial at 12 o'clock will probally be around 7-8 PSI) Just a helpfull hint while tunning that i had to find out the hard way .

 

ok thanks guys, rather than a T connector can I use the Y connector that comes with the boost controller?

What power source did you guys use (which fuse if through the fuse box, if it matters)?

And are you able to hold steady boost w/o spiking between primary and secondary turbos.

 

double post, see below.

 

-yeah, just unplug the boost gauge vacum line from the manifold. plug it to the Y connector along with the hose coming from the profec b. then run a small hose from the last plug on the Y connector back into the manifold.

-i dont think it matters

-according to your mods. with dp, cb, and intake i had complete control. when i addded the mp i couldnt keep ot below 14-15psi. but after porting the wastegate and adding a restrictor plate in the exhaust, i can keep it stable pretty much anywhere with a spike here and there. im sure every car is diffrent though.

ok thanks, got it installed yesterday... now i just have to wait until my motor is broken in to tune it! thanks for the help
