alien what do you have your "start boost" set at?
|
Alien I just ordered mine, you should take some pictures of the install :)
|
I have one that's 2 months old if anyone is looking. Just PM me. Thanks!
|
i have the start boost at 7 psi
|
what is the purpose of the start boost function, im gettin cunfuzled with this thing. right now I have it on off so it will run 7 psi. I dont understand how to make it 10 psi, or how to read the psi levels your getting . im gettin weird menus.... haha
|
I have a Greddy E-01 and the start boost function keeps the wastegate completely closed until the boost passes the start value.
|
what about just opening it up and changing the blue and red? so that its usually red and warning is blue?
|
i have a PowerFC... and i bought the SPEC II version to install but was going to sell it (never installed).
is it more solid than the power FC? should i keep it? will |
very nice write up by the way!!!!!!!!
if i keep mine... i will definately benefit from this!!!!!!!!!! |
Quick question, I noticed that there is 3 orifices on the solnenoid. I will be using the "com" and the "on" port, but do I have to plug the third? The instructions mention nothing about plugging any of the ports...
|
The manual does say to remove all the plugs, but I'm confused too.
Also, after I installed this, I seem to be having issues with my boost. I used version two. Something doesn't seem right. There's boost studdering and a weird non-smooth turbo sound. Any input? I'll be dianoising tomorrow. |
Can we resurrect this thread?
I just installed my specII following version two of the write-up on my automatic 93. Installation was smooth and the unit is easy to work with. I am running stock exhaust and I think I may have made the vacuum line to the valve a bit longer than necessary. I also have no idea how to tune this thing whatsoever (I know how to operate it just don't know the correct settings). For one or more of the above reasons the car is slow as balls, mostly a horrible response. Tomorrow I will try 37% SET, 1% GAIN, and 7% GAIN SET (start boost). Hopefully it won't spike and I will get a good response. I got 11 psi with a 15% SET but my GAIN was higher than 1% (10-15%). I am also tempted to try a high start boost and low gain+medium boost because I really miss the stock primary turbo. Can somebody explain to me how this stupid thing works? Please tell me that when I put an aftermarket exhaust and shorten the vacum lines my good performance will come back! I also need to tune it right.... Thanks

one port is for stock wastegate the other is for a external so you plug the one you dont have and run the line like normal. 37% 7% 12 warning and 35 limit
i get 11 psi smooth. best pull i get at any speed. but i think it verys form car to car. |
The manual says to unplug all caps from valve! Are you sure? Could this be my problem?
I have a 93 automatic with full exhaust and intake and I set up the Profec B Spec II according to version 2 (T turbo outlets and T actuators). It seems that the car is not as fast and especially not as responsive as it should be. Everything is in great shape mechanically. I spoke with a very experienced rotary specialist today and he says I should change my setup to Version 1, not to interfere with the prespool. He also said to set the GAIN very low. I am willing to try it since not only I want a more responsive and consistent boost but also he says that boost hitting a stopped secondary turbo could damage it. What do you think? Thanks. |
If you set your START BOOST value close to your SET BOOST value, you will spool faster.
|
Yes I have the same question, are you supposed to plug up the port(s) on the solenoid that you do not use? What size is the plug????
|
should have a plug in it already from the factory just dont remove it
|
but il take a pic since it seem like you dont have them anymore
|
yes, unfortunately I bought this used, so I do not have any of the factory plugs. Also the unit did not come with the smal airfilter, I wonder if this will be a problem?
|
The plugs are not supposed to be in. The Profec will not work correctly without having the unused port open! This is stated in step #1 of installation, and also in example #1 of troubleshooting, in the instruction manual!

I've seen people run them for years without any problems, but there is that element of risk. I quess I just want to be on the safe side. Im sure you can find a suitable filter at your local auto parts store for a couple of ducats.
|
ever since I installed the profec b spec 2 ive had horrible primary boost response.
Im thinking theres something not right with the profec installation. I followed the instruction manual to a tee. I just cant see what the problem is.Ive tried and tried to find the issue with no luck. |
