I have just cheaply got a turbo smart bleed type boost controler. I pipe the controler in between the turbo outlet and the solenoid that the outlet connects to. I have tried everything and can,t get a response out of this controler. What am I doing wrong?

did you try with out the solenoid?

No my subaru tech said that I should put it in front of the soleniod to full the ecu on how much pressure there is.

Yeah, what he said. Install it in-line from the nipple on the compressor to the nipple on the wastegate actuator.

This configuration should work

Even if you do what you have listed, the ecu will learn around it because the ecu thinks it cant control the boost. Hook the boost controller inline, bypassing the solenoid, to the wastegate actuator.

But leave the electrical connection on the solenod plugged in, or you will get an engine code.

ok I just tried it and all i could get was 5-6 psi. I am running 8-9 stock.

Did you try turning the screw on the boost controller in?

It sounds like you are running spring pressure on the wastegate, and not creating the restriction needed to raise the boost.

It shows to turn the screw out for more pressure and in for less. I turned it almost all the way out and got 5 psi.

You should take it off and blow through the inlet, with your mouth, by turning the screw you will be able to quickly see which way will increase or decrease the amount of air coming out of the other side. You want less air to be able to pass out the outlet. That means the turbo will produce more boost.

try turning it in then.

Did you get it to work?

I will try again after work. I did make sure that it was fucntional before I bought it so it should work. Has anyone use a turbox bleed type controler before?

To control boost with a bleed you need a restriction. Is it possible that this boost controller is meant to be used with an external restrictor?

This setup came straight out of a wrx and was working just fine.

So you removed hoses M, L, and K (at least), and put the boost controller between the compressor outlet and wastegate actuator with some 1/4" hose?

Are you sure you have the inlet and outlet right?

I have it T ed off with L on one side and K on the other. I also tryed to T it between L and M. Neither of these are working right.

You're teeing it? I don't understand. You're not still running anything through the boost control solenoid, right?

Any chance you could take a picture?

I wil try to post a picture later. This is a bleed type boost controler. It has to be T ed in order for it to bleed the boost.

I don't think so. If it requires an external tee, then it also requires an external restrictor.

Generally the boost controller is a tee. It has an inlet and an outlet and somewhere also has an orifice (which could be concealed behind something) through which air is bled.

It is a bleed valve meaning one inlet and an adjustable outlet. I was just messing with it and I think it is can't handle the volume that is needed.

Am I suppose to bleed off the air that goes to the waste gate of or the soleniod?

If it is indeed how you describe it, then it must require an external restrictor. If this device was actually marketed as an MBC, I doubt that is the case.

I would be very surprised if it couldn't handle the volume; that doesn't actually vary that much among factory setups.

You're supposed to be bleeding off air going to the wastegate actuator. No solenoid involved. Your Subaru Tech either miscommunicated or doesn't understand how this works.

It is a Turbox bleed type boost controler. The wrx guys put it T ed off of the line that feeds the pressure sensor that tells the ecu where the presure is at. It works just like a needle valve. It bleeds pressure before the sensor so the waste gate will open and allow more boost. I was hoping that I could make this valve work in some way on our vehicle but I guess not.

I guess I don't know much about WRXes, but that doesn't make any sense to me. You install MBCs on turbochargers, not on pressure sensors.

Try installing the boost controller how I'm saying to. Just try.

I did and it did't work. I am taking it back anyways. I will find out more info on it and post the info so we can all know about this product and that it does not work.
