Default Stage 4 and 8 psi of boost HELP!

Hi to all,

Well I finally got a free weekend and got all of the parts in my car! It took a little longer than I wnated it to but we all know that it always does. I had the help of a friend for the latter part of the day, so thanks to him.

So this is what I installed this weekend.

VF-30
Turbo-XS Uni-Chip
STI injectors
Brullen turbo back
Vishnu up-pipe
Lo-tek Pillar and Boost and A/f gauge.
Samco radiator hoses

So I get it all done and finally get to start the car back up, everything was fine (YIPPEE) I made sure that I had no air leaks and that the fuel injectors were not leaking and that I did not have any exhaust leaks at all. So everything seemed just fine. The car idled perfectly no stumbles or hesitations at all.

So I go take the car for a test drive and I start slowly easing into it, the car is really responive to the slightest throttle input still the car is really smooth no miss firing nothing. I finally really put my foot to it and the car surges ahead and it only goes to 8psi and then stops! I did runs in all of the gears and still only 8 psi.

So I come home and check all of the hoses and find nothing un-hooked. I made sure that the little BB was in the hose on the compressor side of the T-fitting and it was and that nothing was on the wastegate side. The hoses to the solenoid from alot of searching are the right way if you believe the manual but I am still not sure. Gray hose with red stripe to the top which goes to the intake tract and black hose to the T-fitting.

So I keep digging and get the ohm meter out and check the solenoid itself, so tell me if the solenoid is good or bad. I zero the ohm meter out by touching the two probes together and it reads zero, now I test the solenoid and it reads zero. So here is the question I think that I remember reading that it should be about 1 ohm is this true or not?? any help would be great!

Also one more question about the Uni-chip my LED is blinking on the chip is that correct or should it be on steady?

Also more info I have the boost gauge tapped into the front right side of the manfold and not the blow-off valve, does this make a difference?

Any help at all would be great!!!!

Thanks Super!

I assume that you are running the ABC, correct? How many turns is it out? Acording to Phil Stage 4 is set for 17.5 with the ABC 3 turns out.

When you say BB on the compressor side what are you refering to? I am running the stage 4 set up now with an HPMBC (much better then the ABC) but when I was running the ABC their was a small restrictor in the line going to the stock solenoid (under the cover on the passanger side), this was removed and repliaced with the Y adapter from TurboXS, with one side going to the solenoid, one to the ABC and the other to the T in the turbo line. I can't remember if the Y is directional or not.

Since you are only getting 8psi it sounds like some thing is blocking air flow to the ABC/Solenoid or not allowing it to bleed out in order to slow the wastegate opening. When you did the install did you unplug the solenoid when removing the passanger side fuel injector shield?

Hey Troy and BigHurt,

Yes the restrictor is in the right place on the turbo it is in the line off of the elbow that comes out of the compressor and before the "T"

Troy I have the ABC installed but it is only turned out about half a turnm, I thought that the boost was tuned into the unichip for 17.5 psi at sea level and then has to be adjusted for higher elavations I could be wrong though. I will try to mess with the BAC tomorrow.

I did not un-plug the solenoid during the install and I ohmed the solenoid out today and it read 0 ohms so this might be the prob I just do not know yet.

I have a profec installed in the car it is just not hooked up yet so maybe that wil be my solution.

Thanks Super

you need to take the stock solenoid off the loop. Plug the hose with something (a screw does it). I had stage II and with the ABC tuned down all the way I had the designated 16.5 in 4th gear... I am sure something is not right. Did you remove the little restrictor that comes as OEM? I did remove it and I got very low boost... I was freaking out... I added turns on the ABC not a huge effect... I finally asked away here they said yes you need it. I added it up and forgot to turn down the ABC the first run in 3rd I got 20 psi (I almost wet myself...) stopped right there and start turning the ABC down... Finally I am ready to take off and test it out... look beahind my car and a CHP dude is there with his lghts on. I was like $hit... But no sweat he wanted to make sure I was ok...

Check everything and if still no cigar call Mark and he will help out...


Cheers

Nick

Phil told me that the Stage 4n Unichip is set to boost 17.5 with the ABC turned out 3 turns (this is at sea level). I know that this is different from stage 1 and 2 setups where the Unichip is set for the 17.5 psi with the ABC closed. When I installed my stage 4 stuff the ABC was closed as it had been when I had stage 1 and 2. With it closed on stage 4 I was getting 13psi tops. After talking to Phil I opened it three turns and wala 17.5. If you are at a high elevation you would need to turn it out more.

If you unhook the stock solenid and just run the ABC you are essentially using it as a MBC and the Unichip is nolonger controlling boost. This is not the intended purpose of the ABC and if running it this way you are better off getting a ball and spring MBC.

Question

my boost gauge only shows 8 psi in every gear too. my friend and i checked all the fittings and hoses and everything seems fine. my car is stock too. maybe the gauge is messed up? my car is as fast as it was when i first got it, so i know i am making more boost than that. i have an autometer phantom gauge.

is there anything i should check?

Hey Troy

I will turn the ABC out 3-turns and see how it goes today. I am at 62 feet above sea level here in Vacaville. I hope that this is the problem that I am having.

Nick, the little restricto is still in the line on the turbo and since I do not have a manual boost controller there is no way to take it out of the loop.

AK, I also have an Autometer gauge and am getting the reading that you are getting, I am pulling about 18-19 pounds of vacuum at idle so I do not think that the gauge is bad.

Just keep turning up the boost with the ABC. I needed 4 and 1/2 turns to get 17 PSI. I've since put an MBC on and it runs much better. If you use a cheap $25 MBC you can still tee in the turbo xs abc and make it do the same thing as a Turbo XS HPMBC.
Just open it up half a turn. It works wonders.

I wouldn't use an MBC until you upgrade the turbo to a more laggy unit. Drivability goes out the window.

yup that sounds right. I get 18-19 vacuum at idle and I have an autometer as well. I also have a TXS HPBC. Seems to be keeping boost much steadier...

Talking

Hey thanks everyone,

Well the power of the I-club has once again prevailed!! I turned the ABC out 3.5 turns and got 16 psi!!! You cannot believe how happy I am that this problem is fixed. I will fine tune it later to 17.5 after everything kind of gels together and the ecu re-learns everything.

I will try and post some pics of the car later on this posst or in the gallery!!

Later Super

Super Hawk, I know the feeling. After 2 days of install I go out and only got 7-8psi. I was pissed, thinking I should have stayed at Stage 2 where my car was running fine. Then after talking to Phil and cranking out the ABC I was in Heaven.

BTW I am not sure how hot it is there, but beware that if it is hot and you turn it up to 17.5, when it cools off it will be like 18.5-20. Phil said that there was no problem with running 17.5 when it was hot but just remember to turn it down if it cools off. I had the opposite happen to me, set the HPMBC to 17.5 when it was 60 out then when it got to be 90 I was only running 15 psi.

My car ate gas after the install for the first few tanks (this was not helped by my lead footing) but now it is back to normal if not better depending on how much I get into it.

Hey Troy,

I already know what you are talking about, it was really cool here this morning and I was running about 1.5-2 psi more in the morning compared to the afternoon when it was about 90 here at the hottest. This setup is just awesome!!! I would encourage anyone who is thinking about it to just make the leap and just do it. By the way did you install a fuel pump also?? I do not have a larger one on the car as of yet.

Again thanks for all of the help!! I just wish that TurboXS would have sent me the right instructions with the unichip and none of this would have happened!! They could at least have them on the web so that you could down load them!!

Yeah I am addicted to the sound of the exhaust on the car, it is totally awesome!! I can believe how fast the car revves now it is unbelievable!!

Later Super!!!

Yeah I installed the Walbro, had to bend the FP holding a little and zip tie the FP on as it is a little longer then the stock one. I know that some have not used a bigger FP and been fine I think it is more of a safety thing. For in town or the ocassional romp on the throttle there should be no problem, but if you were going to the drags or a raceway all the time then it may be worth the $130. Plus it much easier to install then the Injectors, no bolts that are about impossible to reach.

Hey Troy,

Yes I do not know if I am going to take it to the track or not, I would like to know what the car would run in the 1/4 now that I have done all of this work to it. I will have to recover from this weekend first and then I will tackle the fuel pump issue. You are right about the injectors being a pain in the a** !!!!

I put one in my GSX when I had that and it was not to bad to install. I have not looked into how it is supposed to go in as of yet but I am sure that I will do the reasearch when the time comes. So where did you get your pump from? and what is the part # for it?

So what else have you gotten done to the wagon?

I got the pump from TurboXS not sure which Walbro it is, buts a 255 liter pump packaged by BBK.

I wrote some instructions for the FP install if you need them, I will just have to dig them up.

Aside form the Stage 4 with HPMBC I really have no other power mods. I have removed the roof rails, installed some gauges in the center pod, some small stereo stuff, and new Rota 17" wheels and Kumho tires for the summer. I had a set of Eibach springs but decided not to use them as I had read about some rubbing issues on the wagons in the rear with 17". I may pick up a set of Prodives as the seem to lower the rear a little less so hopfully there will be no rubing issues. I also want to pick up a sedan rear sway bar and install it at the same time.

On the performance side I have been looking at the APS FMIC that Cob sells but I am waiting for TurboXS to come out with their new intercoolers, both TMIC and FMIC, to make my decission. I also have a SBC-id that I picked up cheap but I am waiting to install it as there is a rumor that a new user programmable ECU is being announced come mid July.
