Help Setting Up My Profec B Boost Controller

[cuong nguyen]

Hey guys need help setting up my boost controller. I can seem to get it to run anymore then 0.4 bar of boost. Have a gt3076 with 38mm external gate.

Any help would be much appreciated.

What settings should I be on?

how have you plumbed your external gate to the solenoid?

Here are the instructions on how to install it to an internal gate and an external gate. Makes a world of difference when its wired up properly

I have the newer one to that it's the digital one and it's silver.

Yeh I have it plumbed right it's just the settings I just can't understand them.

SET is how much boost you want

GAIN simply put it, too much and boost will spike too little and it's lazy

Newer Profecs also have the Start boost, which works similar to the GAIN

if nothing is happening, you've plumbed it wrong

So its a Profec B Spec II, should be the same set up wise anyway when plumbing in the wastegate/actuator

Yeh one side to the bottom of the external the other side to turbo compressor.

Oh ok well when I turn the controller off it goes unlimited boost. When on it runs .40 bar. I'm surprised that there is a .40 bar spring lol who wants to run. Like 6psi wtf

Sounds like you've plumbed it wrong already

When it's off it should only be gate pressure

Ok so how do I plum it?

Try googling profec b spec II instructions,

Seriously takes the whole of 2 seconds to search for yourself

This is by far the best article I came across when setting mine up.

Follow the process

Sounds like you have the NC and NO mixed up, try swapping the fitting into the other hole if it has one.

You have an external gate, why don't you just swap in a heavier spring? No need for an electronic controller really...

yes and no, the gate cracks open a touch before it reaches its defined gate pressure (if you want to call it that) running an EBC and utilising both top and bottom ports can keep the gate closed a little longer giving you a flatter boost response, instead of gentle ramp

I tend to like to let it spike a little and then the boost to settle, but that's just me
