You have a Profec B, correct?

Just out of curiosity, what did you set your duty cycle to for 21 PSI?

 

My duty cycle is set at 64% Gain is 19 Start Boost 1.19 Limiter at 1.45bar Limiter 20%

Smooth to 20 psi

 

Nope, just commenting on the fuel requirements for running 21 psi.

Hmmmmm I am confused...I just bought my Greddy Profec B aswell.........I thought the COM goes to the wastegate actuator and the NO goes inbetween the intake and bov.......

 

NO line connects to the bottom of the turbo, on the old line there is a tee one connects to the wastegate and the other to the bottom of the turbo. All you do is place the Com to the wastegate act. and the NO to the other spot the Tee was connected and bam your all set.

 

Quickshift is right, it was that simple. Thanks for your help, I'm on my way to one bad a** Evo VIII.

 

is it mandatory to cap off the stock solenoid ......i left mine uncapped.....? what can happen with this uncapped?

 

if you dont cap the stock colenoid will it cause a cel?

 

I left mine hooked up to a small filter breather I had laying around and I've had no cel.

 

No it wont cause a cel but you should plug just for safty sake so no water or dirt gets in the mechanism.

 

I completely forgot to plug mine off. I probably should do that later.

 

i had mine installed about a month ago, and last week i started hearing a clicking sound coming from under the dash on the drivers side where the fuse box is. it only does it when the bc is on, and when the boost increases. it sounds like to me like a relay opening and closing. the installer checked everything and it seemed fine. there is no other problems that is related to it. i also have a hks tt. any ideas of what it is or how to fix it?

 

Is it coming from the hood or from inside the car? Cause if it from outside it is normal. Before I did my exhaust install I noticed the sound from the boost solonoid under the hood, but that is normal for the solonoid to make those sounds as it is adjust the flow of air to the wastegate. But if it is coming from inside he may have connected it to a rely or something to power it.

 

Quickshift is correct. It's the stepper motor you're hearing. It's nothing to worry about. Just turn your stereo up.

 

the installer said he connected it to the power source going to the radio, is that bad a idea?but i will try to listen more where its coming from. thanks for the response.
