Alright guys and girls, lets see if we can help a fellow Scion owner out with a turbo issue, here is their issue:
05 xb turbo'd trouble, spudders, check engine light come on. Basically it doesent run good.


I'll start with some questions. What kit are you running? How long has it been on? How long has it been running like this? Has it been dyno tuned? Do you do the install? Do you hear any knocking? Does it idle real rough?

I can come up with a million more, but this will help start us off.

First off, what kind of codes are you throwing, Im assuming you have scanned to see what the issue may be...check all your connections for the i/c, make sure theres no vacuum leaks anywhere, check to make sure the gaskets didnt blow on the manifold, check your MAF sensor, pull your plugs and see if they are fouled ummm, I dunno, we need some input other than what was stated

http://www.clicksmilies.com/s0105/fragend/confused-smiley-013.gif Dont know what happened to him Vito. Guess we will just have to wait and see if he comes back on to answer the questions and gives us more info. :tap:

We might have to post something completely off topic, then he may ask that question again in the thread. :P

ok i just had it put on 3 weeks ago . the turbo kit from turbo kits .com tsi? greddy emange, 320cinjectors, perrin rail, magnaflow cat back,been tuned 6 times and dyno. cant floor it because it spudders and back fires. check engine reads running to rich, and map sensor.and its auto xb. not knocking,a little rough start(idle wise). and i'm not really a turbo mech this is my first turbo.

Do you have a boost guage and an Air Fuel gauge. If you have an A/F gauge, what doe it read at WOT?

Sounds like you are running super super pig rich to me, but lets see what the others have to say.

i have bosst gauge and if i floor it it reads 12

if anyone would really like to help feel free to call, 240-271-8781, jason.

Holy mary mother of boost, your boost gauge is reading 12psi when you floor it. Okay I would say no more flooring it until you get the engine rebuilt or the boost turned down or your engine could go south very quick. You really need to get an A/F wideband gauge, so you can see exactly what the air/ fuel is doing.

Did you check all connections, pipes, etc. to make sure there were no leaks like Simplyscion asked above? Did you take it back to the shop that installed it, to see what they said about it?

if anyone would really like to help feel free to call, 240-271-8781, jason.

I would but im at work, i can play on the internet but phone calls are restricted to customers only. Plus i am no expert and I think others may have some good ideas on what is going on. I will just try to extract all the info out of you that I can and then we can piece the puzzle together.

alright, first off, theres no way in hell you should be hitting 12psi without a boost controller. I had that kit and mine was automatic as well, and it comes with a 6 psi spring in the internal wastegate so I dont get how you are hitting 12psi unless you are spiking out really bad which could be a possibility. Also another thing is you could be maxing out the MAF sensor which would cause the car to run like crap and just dump more fuel. I asked you before but I dont think I got an answer, but what kind of codes are you throwing...is a P0172 system rich bank 1?

yeah took it back and they cant figure it out

it has read system running to rich , what does spiking mean , and can you call me?

hey Im at work just like proshop but Im off tommorow and would be more than happy to help you...If you want pm me and I will give you my cell phone number. I gotta go drop my Bull Terrier off to get his ballz chopped (cause hes trying to fight to much with my other dogs) off in the morning at around 9 but I will be around after that if you wanna give me a shout.

were do you live and whats your number?timezone?

First thing to check are your vacuum lines. IF you have a leak from the turbo out line to the wastegate, youre going to run much more boost than whats its supposed to run at. If you want, send me your Emanage file. I have similar mods and I can compare your Emanage map to mine.

dont have my emange files sorry i'm a newbe

hey bro, ur in md, im no turbo expert, but try contacting the guys from ptuning, they are out of manassas va, or the guys from VIP Garage,

i usto live in nova, in fairfax actually. thats the only advice i can offer u right now. the guys at ptuning are great, and have great service, the guys from VIP i dont know, they seem to have decent service, but a like 2 years ago the offered me a sponsorship for my xA turbo, and then disapeared. the company went shut down and all of a sudden these guys showed up with a new name...take that one as you want, but those are the two places i know of in the dc area.

dont have my emange files sorry i'm a newbe

hmm, I would go back to the place that installed the turbo kit. Have them check out your vac lines to make sure there are no leaks causing your boost spike. Stay OFF boost until you get it resolved. At 12psi, the popping is your detonating and running super lean.

Sounds to me like a horrible tune. I ran almost the same setup you have there without the emanage. Try disconnecting the emanage, resetting the ecu and try that. The only stumble I had with mine was when it built boost HARD on takeoff. As for the boost level, that could also be the problem. If you are pushing 12psi, you are making your MAF all retarded. As I mentioned before, it sounds to me like the tune is off. The factory ecu probably keeps overiding the Emanage. Did you take it to a tuner that knows what he is doing or did you take it to someone that says they can do it at their house?

Its definitley a tuning/MAF issue. As for the boost, its not going to come apart. I ran 10psi everyday without an issue...

I talked to him on the phone, he blew his headgasket the day after I told him to reset his ECU...it started driving nice but then he pulled out of the parking lot of some store and all of a sudden "POP".

LIke I said...with that kind of boost, he is going to lift the head before it comes apart....

Everyone thinks these motors cant handle the boost mechanically. They CAN handle it mechanically, just not electronically....

Ouch, that sucks, best of luck to you jaw8623, hope you get it taken care of and back on the road real soon.. Thanks Vito for calling and helping him out.

thanks everyone for all your help, i think i'm done with small cars. back to big blocks.

Wanna sell that kit?

Lol here we go again stu...but I agree with stu 100%...these cars will hold the boost...I have hit 13psi on numerous runs but with my return line and safe tune it held out...god knows what has happenend since then with the car cause I haven't heard from the dude who bought it from me

Yea, I like my charger, but it would be cool to have a turbo setup sittin here on the shelf just in case...LOL... Its all about the tune with these cars. Mechanically they are fine, but electronically, thats where the problems come up. I am in the process of doing a MAF pipe right now for a test car and also goiing to be installing a MAP ECU in an xB to give that a shot which removes the MAF totally....

on another note Vito, you going to SEMA this year? I booked the trip the other day so I will be out there. We gotta get together for some brews if you are out there...

I gotta talk to my cousin and see if he can get me in there through the business expenses...We definitely do gotta get together, I fell asleep that night that we landed and then you left Vegas the next day :rofl: :doh:

Sorry to hear that Jason.

I never got to see your car since you told me you had turboed it.

thanks brian

My car used to sputter and backfire a lot too. Now it never does. First thing I noticed was it backfired less when using a good super unleaded gas. Then, one of the things I used to do is reset the ECU by unplugging the EFI fuse then it would run pretty smooth...for a short distance! If I didn't do that, even starting the car was not easy, it would idle rough and I would need to step on the gas some untiil it warmed up. Later I found out the main reason why I had to reset my ECU so much, (ie. every time I took my car out) was not only because I had a piggyback system (had an apexi SAFC2 before) but there was a huge crack in the exhaust manifold that leaked exhaust like crazy, so it was impossible to tune and the ECU would readjust a lot quicker. Another time after I replaced my custom turbo with a greddy turbo kit, as they were tuning it, it would just lose power after a little bit which was caused by a bad fuel pump. It was weird because under normal load it was OK, but under boost after a couple runs it would not pump the fuel as it should. I don't know if any of this will help, but I understand your frustration. It took me over $7k to fix my problem which includes replacing my turbo with a greddy turbo, getting the fuel system in place, the haltech, and stage 3 clutch plus some little things here and there.

but now your box is tight though :P :bow:

but now your box is tight though Tongue Bow

That's right Vito! If there is anything I can complain about, it's 1) the stage 3 clutch is not very forgiving as a stock clutch especially in 1st gear, and 2) I wish I had more boost!! :P

well, chalk up another blown up box...I ran into the guy who bought my xB and he blew it up doing a standing 3 gear burnout lol :doh:
RIP Boostbox

yea man, make sure your block numbers match up when you get your car back lol...make sure they didnt blow it up and replace it :rofl: :P
Well, the good thing was that I beat the snot out of it and it took the abuse for a really long time...never did no 3 gear standing burnouts but I rocked the wheels off that thing pretty much and it took him only 5 months to blow it up...lol

:rofl: :rofl: Hey as long as it got replaced I could give a $hit. It's all gonna get switched out in a few months any way... :lalala: :lalala:

So how much was it boosting when it blew?

9 psi...he upped it to 9 after I sold it to him and ran it at that for the whole 5 months

But if he had reset the ecu like you told him, the 9psi should have been fine, right?

absolutely with the fuel setup I had

I think what happens is that even though 12.5 is ok for us going FI, the ECU might see that as too rich. It will accept it for a while but then start trimming the fuel causing it to go lean. Thats what my car is doing right now.

its exactly what happens...the car runs so rich in the beginning and then it starts to lean itself out back to a 14.7...hence why I had to reset the ECU every few days

AEM is actually making a plug and play for the XB. Im waiting for that right now so Ill let you all know how it goes. Ill either go that route of Megasquirt.

Rollhard, I wish I could get you the info you needed for the haltech but I guess it's hard to get in touch with the people that tuned my car. Oh well, I'll send them an email every so often to see if I can get some response. I've driven about 400-500 miles so far and the haltech is working like a charm since the day I got it.

please do megasquirt...I have been dying for someone to build a setup for these cars...I think it would prove quite useful and its so inexpensive for such quality results :bow: :pray:

I will try whatever you guys want. lol. Im just testing different products now. It will all become useful later on.

Question, I have the opportunity to get my hands on the greedy xb turbo. The thing i remember is i belive the xa ecu will not play nicely with the emanage. I belive the Tien xb had this issue and resorted to something. Will the greedy xb kit fit my xa 06, and besides the return fuel setup and necessary clutch, boost guage, wideband a/f, will i be able to live long on 6psi? Will this kit be more fab than its worth, compared to the Tsi entry level. ZPI's is alittle to expensive. Is the whole issue with the greedy xb kit my stock ecu, and how do i over come that. The aem standalone, i was told would be overkill.

If your XA has the same engine to firewall clearance then the xb kit will work. I am sure the XA and XB ecu pin out for the 06 is similar. If you email Greddy, they will send you the ECU pin out for the XA so the Emange would work. No, the stock ECU doesnt like anything like a piggyback messing with it so you might have some problems. I know some people, myself included, are trying different fuel and tune set ups. We are getting pretty close now. Who said EMS was overkill? Maybe its just out of their budget. AEM is working on an EMS p&p for the XB. Once that comes out, I will go with that if the megasquirt dont work.

megasquirt will work...its gotta...go out and get it done already :P

Haha, man, Im doing so much to this thing so you guys get more info. Am I the new labrat? :silly:

Im jk though. So far, I am changing different set ups and its getting better.

hey, someone needed to take over mine and lastlookcustoms spot sooner or later :P
