3lbs no matter what i do...what can be wrong
 

i have a manuel boost controller, i turned the thing all the way to the left, it is still at 3lbs, i turn it all the way to the right, it is still on 3lbs.....can the safc have anything to do with it? Before i was able to control it, but now i can't. What are all the possiblities that can be wrong?

Re:3lbs no matter what i do...what can be wrong
 

ummmm leaks

Re:3lbs no matter what i do...what can be wrong
 

My compressor housing was leaking.I siliconed the bitch and now its gangsta.

If its a t3 check that there is a gasket between the compressor and housing.

Re:3lbs no matter what i do...what can be wrong
 

so it oculdn't be on my deltagate wastegaste right?

Re:3lbs no matter what i do...what can be wrong
 

i have an idea....follow my directions carefully...
1) take off MBC
2) take off whatever filter you have
3) go try again....
[your taking off the MBC so you dont hit too much boost]


i took mine off tonight...started to pull ------ hard, i look over at the boost gauge as it hits 15psi :o and let off...

Re:3lbs no matter what i do...what can be wrong
 

what kind of filter did you have on it?

Re:3lbs no matter what i do...what can be wrong
 

sounds like leaks to me. make sure all your clamps are on tight.

Re:3lbs no matter what i do...what can be wrong
 

no leaks....at all....

Re:3lbs no matter what i do...what can be wrong
 

I was having a similar problem today until I crushed my dsm bov. Now it boosts fine. If your charge pipes are good, it sounds like you've got a bov or wg leak.

Re:3lbs no matter what i do...what can be wrong
 

i took out my mbc and connect the turbo straight to the wg, it boosted like 1 lbs...i took out all the vaccum lines where the turbo and the wg is not connected, it boosted like 0 or 1 lb i forgot but yea.....not seems to be loose....could it be the turbo itself?

Re:3lbs no matter what i do...what can be wrong
 

I didn't see what turbo you are running, but is it boosting quickly to 1psi and then sitting there until redline, or is it only reaching 1psi at or near redline? It is leaking somewhere. If the turbo spins freely and doesn't have any play it should be ok. Try blocking off the wastegate if it is external. Use a steel plate bolted to it, pref with a gasket, and see if it still won't boost. If it still doesn't, you know the wg isn't the problem. Look at your bov and chargepipes. If it is an internal gate, maybe disconnecting the vacuum will allow you to test it? I'm not sure about that.

Re:3lbs no matter what i do...what can be wrong
 

when it goes about 3000 rpm then it is at 1lb and stay there, when the vaccum is directly connected from the turbo to the wg, ....i also tried unpluggin all the vaccum hoses, same thing it is still at 1lb......i put all the vaccum hoses back ...then nit goes back up to 3 lbs......beside the leaking theory, could it be my turbo?

Re:3lbs no matter what i do...what can be wrong
 

are you driving it down the road or reving it in your driveway? cause if theres no load on the engine you wont boost much

Re:3lbs no matter what i do...what can be wrong
 

driving

Re:3lbs no matter what i do...what can be wrong
 

i say you have no or little oil going into your turbo

Re:3lbs no matter what i do...what can be wrong
 

you try taking off the filter?

Re:3lbs no matter what i do...what can be wrong
 

Is this an internal wastegate? Though with the boost controler this shouldn't be an issue, but might be something to look at... Check out the wastegate actuator braket and arm and make sure it is not bent. The actuator could be leaking also. I had one that went bad on me once.

Re:3lbs no matter what i do...what can be wrong
 

I dont mean to steal the thread but im having the same problem as well. Ive checked everything. Hey tranceminister didi the actuator swap work out. Cause all i hold is three as well then from 4k it start fluctuating like a springboard. Sorry for asking another question and not answering one. :D

Re:3lbs no matter what i do...what can be wrong
 

Well when I found out mine was bad I swapped it for an external gate... so in that case yeah it did work. But, you can find internal actuators at a decent price on ebay or go junkyard hunting. I'd say it's worth a shot.

Re:3lbs no matter what i do...what can be wrong
 

well do thanks for the input.

Re:3lbs no matter what i do...what can be wrong
 

i have a external wg, i checked it, i took out the filter and drove, it is still the same.

Re:3lbs no matter what i do...what can be wrong
 

oil problem, i'm tell you mang. if you can only hit 3psi your turbo is fuct

Re:3lbs no matter what i do...what can be wrong
 

Trance you are the funking man!!! ;D I did it and the boost shot up to 15. Thanks for the help. :D :D :D

Re:3lbs no matter what i do...what can be wrong
 

okay, i fixed the problem, it was leakin air because one of the rubber connectors for the chargepipe was crack open.....but now i have another problem, when i full throttle my car bogs out like it doesn't has enough fuel..then the check engine light come on...it says the tps sensor, o2 sensor, and the map sensor. the werid thing about it, when those error codes appear, it always appear together. I never had the check engine light on wiht just one problem, it is always those 3. I have a missing link, but i thought if u have a safc...u dont need the missing link anymore. I was only boosting like 7lbs.

Re:3lbs no matter what i do...what can be wrong
 

So is it hooked up or not . The missing link that is.Are you running the 450 injectors with the hack. or are you using an Fmu?

Re:3lbs no matter what i do...what can be wrong
 

Yeah, please let us know everything in your setup. If you are running the AFC, take out that missing link... Also, what are the Safc settings? Sounds like it's not setup correctly.

Re:3lbs no matter what i do...what can be wrong
 

running the injector with the safc, and no missing link

Re:3lbs no matter what i do...what can be wrong
 

Uhrm,uhrm...

Re:3lbs no matter what i do...what can be wrong
 

When I first put in my dsm 450s and my SAFC I had no turbo, so I started with settings of -40% across the board. Even though that shouldn't have been too lean, it apparently was, and I kept getting the problem you're describing upon deceleration and heavy throttle. I'd reccomend actually increasing your settings (to about -35%) and see what happens. It's counter-intuitive, but it worked for me. Until I started using Uberdata. ;D Now it runs like a champ.

Re:3lbs no matter what i do...what can be wrong
 

okay how should i set my safc, haha id ont realli know how to set it, give me a clear detail on how to, :)

Re:3lbs no matter what i do...what can be wrong
 

Well firsto off, for vehichle settings, Select the 4cyl. mode. Then 06in-06out, select the arrow pointing up and to the right a bit(not sure how to describe it). then dial in your AFC correction areas and you'll be good to go. Check out the "new users" section of Forced induction. I'm pretty sure theres a writeup on how to set the AFC up.
I'm basically going by memory and don't have my AFC anymore, so anyone who knows for sure what settings you should start off with could probably help you out.

Re:3lbs no matter what i do...what can be wrong
 

okay....um....im currently boosting at 7psi with a t3 garrent turbo with a external deltagate wastegate on a ls engine...what should be my settings be around? I will need extreme details because im such a newbie, i would test/tune it, but i dont know will that fix my problems, so i will tune it at home and if the problem do go away, then i willl go test/tune it.
i wanna know the information on everysingle setting on the safc, if u guys can help me. the Hi/Lo - thrtl...Th-point....Ne-point.....dec. -air....and everything else i will need. Thanks guys......n girls? haha :)
