I just finished installing my Greddy Profec b spec 2 and am only seeing max boost of 10psi. I've followed the instructions to the letter and connected the com line to the actuator and the no line to the turbine nipple. I have no kinks in the lines, everything is connected. I have messed w/ the settings a thousand times, so at this point I'm at a loss. To make matters worse the unit will not alow me to change fm kpa mode to the psi mode. I don't have any other mods at this time if that matters. I would appreciate any input that anyone has to give

 

What are your current settings? Duty cycle ,startboost stuff like that.

 

First of all, in order to change from kpa to PSI, the EBC must be turned off. In the off mode, hold down the select button and press the mode button twice before two seconds expires. Upon doing so, you will see the x100 kpa in the lower right window dissappear. Once in PSI mode, it reads in the hundreds (14.5 psi = 145 on the EBC). Second, remove the plug from the side of the black solenoid box in your engine bay (The solenoid box is the black box that says Greddy on top and has all of the hoses connected to it). The side of the box has a hole that is plugged from the factory (To keep dirt out). However, in order for the EBC to operate properly, the plug must be removed. That should do the trick.
Peace,
Jack

 

are you talking about the NC port??? if so I've read somewhere on this forum that its to remain plugged....is that incorrect??? sorry for all the drama and questions but I appreciate everyone's help...

 

as im not getting any more then 10 psi, i've only played around w/ my settings as follows

set 60%
gain 0
start 15psi
warning 20psi

 

check all the connections

sound like your running only wastegate pressure

 

Check this out. I had the same problem!!!!!!!

Thanks for the link, I've read on other people's installs of this same boost control that I have and they have all taken out that tee that leads to the actuator and turbo from the old boost solenoid and replaced it with two new lines. I did notice that my new lines are a little long but still are not crimping anywhere, does the length of the lines make a diff? if so should I just snip off a piece to make them shorter so that I get more direct, shorter lines?

NorCalEvo,

Check out the link above for directions, but I believe that on page 9 step #1 it says to remove ALL the plastic plugs on the valve unit!

There is also a note about the 4G63 engine on page 6 about properly hooking up the line going to the fuel pressure regulator, but that shouldn't be causing the problem.

 

Thanks, I tried unplugging the cap and unfortunately that didn't work, I'm begging to think I just have a deffective unit. As in terms of the boost gauge vaccum line I didn't even hook that up, as I already have a boost gauge. Does anyone know if its suppose to be hooked up in order for the unit to work....?

 

how is it gonna know how much boost is present without it hooked up?

i mean i'm not too familiar with EBC, as i use MBC, but i would assume it would need to know how much boost is being run so it could regulate it.

as 10 psi is how much the wastegate runs at

 

Totally Correct.... I read somerwhere here on the forum that they didn't connect their boost gauge line and figuring I already had a boost gauge I wouldn't either. I thought the unit somehow measured boost fm the solenoid. Thanks for your help.
