UTEC newb, need help

zoomy · 04-27-2006, 10:49 PM

I'm not boosting past ~10psi. The restrictor pill is in place and I've tweaked the ABC till the cows came home. Now I have a house full of cows and a Stg2 rex with no more than 10psi of boost. FYI, that's what I started with in the first place. The car has had a UTEC installed in it by the previous owner. When I do 3rd and 4th gear pull at around 3k rpm it boosts fast and stops at 10psi and feels like it wants to go higher, but won't. Any help would be greatly appreciated. Thanks.

Show me your logs.

Gethin · 04-28-2006, 01:19 AM

check the hoses connected to the bcs and make sure the lines are not blocked and the solenoid is working, flush the hoses if you like with brake cleaner. Make sure it's all plumbed in properly.

TurbojonLS · 04-28-2006, 10:31 AM

What values are in your boost map?

zoomy · 04-28-2006, 01:27 PM

I'm using the base stg2 map from turboxs' website...I believe the target boost value is 350 or 375. I only just learned how to actually export my logs so I'll do a run after work today and I'll post it. I've checked and replaced (with correct diameter) all of the hoses exception of the hose coming off the compressor housing.

Freon · 04-28-2006, 01:46 PM

The boost map must be tuned. I wouldn't worry until you can't reach target boost with "450" in your boost table.

SloRice · 04-28-2006, 02:38 PM

Make sure the restrictor pill is on the correct side of the turbo. I want to say I think it goes in the line coming off the compressor housing.

zoomy · 04-28-2006, 03:19 PM

Ok, so I'm getting one consistent answer between forums...I must begin tuning the boost map. I have checked, double checked and triple checked the pill and it is where it needs to be. Thanks for all the input everyone. Hopefully I'll have a success post in a little while and someone who's having the same problem in the begining can learn from my screw ups, lol. Thanks again, everyone.

zoomy · 04-28-2006, 04:13 PM

OK, so I edited my stg2 boost map and am still getting no results. I took the 100% column and the 90% column up to 450 and 400 respectively. I also screwed the ABC all the way in and tried backing it out a few turns. Nothing. I check the BCS' function and it is good. I'm at a loss.

SloRice · 04-28-2006, 04:19 PM

OK, stupid question, but are you modifying the current map that you are running??

zoomy · 04-28-2006, 04:27 PM

Yes...hopefully that wasn't a stupid answer

TurbojonLS · 04-28-2006, 05:08 PM

Do you get different boost when running the stock map? Have you always only gotten 10psi?

I'm thinking you might have a post-turbo leak. Are you running a BOV by any chance?

zoomy · 04-28-2006, 05:19 PM

I have always gotten 10psi never more. I'm not running a BOV. I've always kind of suspected a boost leak somewhere, but have never found one. I talked to Nathan at TXS and he went over my hose routing, which is ok, went over some of my settings, which were good. Then he had me pull the hose off of the wastegate actuator, which yielded 13psi. He told me that I should have been getting way more boost and that something is probably wrong with my turbo (makes me almost cry thinking about it). I'm praying there's a way to fix this that isn't replacing a turbo component.

SloRice · 04-29-2006, 12:54 AM

can you post a log?

zoomy · 04-29-2006, 01:22 AM

I suppose I can, but I don't see how it will show anything. All it does show is at 100% TPS I hit my target boost of 450. The only problem is that I still only hit about 10 psi. The only time I hit higher is with the hose pulled from the WG actuator, and then i only hit 13 psi and it doesn't shoot up or anything, it spools as normal as the 10 psi.

TurbojonLS · 04-29-2006, 09:42 AM

I'd say the next step is to borrow a local's TMIC & associated hoses to see if it changes things. Basically get the Y-pipe, TMIC, BOV, & TMIC - TB hose. If you're still only hitting 10psi, you know you've got other, more expensive issues.

zoomy · 04-29-2006, 06:54 PM

could it still be a boost leak despite not making any more power with the WG hose disconnected??

brutalsti · 05-05-2006, 11:09 PM

PRO-TUNE....spend the money to go fast...they are called pro for A reason

bcblues · 05-06-2006, 08:53 AM

Don't ProTune until you resolve the low boost issue. You will show up for your dyno/tune time, and end up wasting it tracking down mechanical or electrical gremlins. Fix those gremlins before you schedule your tune.

First, make sure you are running the mat that you think your are running. Check it in HyperTerminal Dashboard. Then make sure you are actually modifying AND SAVING the correct map. Replace all vacuum lines, as you could have a pinhole somewhere. Make sure they are not kinked at all. Also check all your post turbo intake tract lines and connections. Sometimes the hoses on the bottom of the intercooler will work loose.

zoomy · 05-06-2006, 10:16 AM

I won't be ProTuning for a while anyway as I'm a 16hr round trip from the closest AWD tuner anyway. They have a AWD dyno in El Paso, but it doesn't read accurate for anything. I'm going to pick up a couple testers this weekend. One for vaccum lines the other I'm ordering and it will be to test for boost leaks. It's a rubber plug with a guage on it that you hook to the compressor side of the turbo, you can then pressurize the system and check for leaks all while the car isn't running. I'm begining to think my wastegate actuator is bad tho, because even in stock mode I only get 10 psi. I've checked all my maps and made sure I was on the right one (I have a remote switch and have double checked with the dashboard in hyper). I bought a stock turbo so I can swap them out and rule out an actual problem with my turbo or wg. Does anyone have any suggestions that may be off the wall of really uncommon, because none of the common fixes or problems appear to be occuring in my car.

zoomy · 05-07-2006, 12:32 PM

UPDATE: I adjusted the wg arm and am now boosting to 18psi....YAY! It feels great. It spools crazy fast and holds great. Hardly any taper. Thanks for everyone's input.

hmanxx · 05-07-2006, 01:21 PM

are you tightening or what to the wastegate arm ???

zoomy · 05-07-2006, 02:08 PM

I tightened it (or shortened if you prefer). I can't believe the power I was missing out on. Now I just have to fine tune it. There's so much power that if I punch it around a corner it'll actually step out the rear end, I never had that with 10psi. I can't wait to autox it again.

Freon · 05-07-2006, 02:24 PM

edit: nevermind you got it fixed.

zoomy · 05-07-2006, 03:57 PM

My whole problem was mechanical, but it was the fact that the wastegate couldn't close enough to get the boost I was asking from it. I just hope if someone has the same problem in the future that they are able to find this thread and give it a try. I did three turns and it doesn't surge or spike. 18 psi feels great.
