Hello.
Initially I was only able to build 12psi after I installed my Greddy Profec B Spec 2. I pushed on the connector that controls the solenoid valve (valve unit harness) and I was able to build 19psi, but it was constantly fluctuating. I decided to go ahead and tug on the valve unit harness and I was only building 12psi again. So I need to get another one of these, but I am having trouble locating one. If anyone knows where I can get one of these fairly quickly please let me know?

 

Greddy may warranty that harness or at the least be able to get it for you quickly. Greddy.com is in California and they have a phone number listed on their site.

If LancerShop couldn't get you a harness you may be able to get one from someone like boost solutions or rev high. I think they are both vendors for Greddy products.

 

I have one company in Pheonix trying to get me one so far. I rigged up a connector to make due while I wait for the new harness and it works pretty well. Thanks Timzcat for all of the info.
The company is contacting Greddy direct to see if they stock them here in the US. If they don't have them they will try and get me one from the manufacture.

 

It appears the part number is the one below

That's all the sites I found that list it. I definitely think some vendors on here could get one, hopefully one will respond.

 

Dude, you are awesome! Thanks again for all the info and help. I will check out those vendors for it.

 

I repaired the pins on the harness and adjusted my gain to 4%, start boost to 10 psi and set to 43%. This gave me a steady 19 psi with only a little fluctuation in second gear when I would nail the throttle. All of the other gears were really smooth and steady. I tried a higher gain, but it would give me more boost fluctuations. When I tried a higher start boost it did the same thing. Maybe some more tunning and I can get it down, but I rather just use a MBC. So, I am handing this one off to my roommate for his DSM. He is impressed with it. I don't really like the electronic ones now. Going to go with the Joe-p E-MBC.
