Alright guys and girls, lets see if we can help a fellow Scion owner out with a turbo issue, here is their issue:

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

 

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.

 

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

 

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?

 

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.

 

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...
