first logs after engine build. please look

[Beemer832]

please let me know if anything looks "wrong" here. Ordering a wideband today so I can accurately monitor AFR. All input is greatly appreciated.

thanks
josh

how do i post CSV files in either a txt or excel format?

[pipe7284]

post vid of how it looks. and sounds.

[Ewok_Fetus]

Something looks wrong... I don't see anything...

[k0mpresd]

take a screen shot when the log is open in excel.

[Nebone]

If you can upload and post pictures, then when your excel is open, click ALT+Print Screen. Open MS Paint and paste it in there and save as a jpg. Upload that to photobucket or something and post here.

[Beemer832]

k just wasnt sure how people uploaded the info here. trying to get it hosted on my HTTP server but i am not having any luck. I will take a screen shot. thanks

[Beemer832]

alas... the power of email..

here is the log file. i will make a better website in the future so I can organize my files better.

[k0mpresd]

whatd you do? sit in neutral, rev, and log? haha.

thats no help to tell if your motor is going to pop when you rip it.

[Poopie]

Those logs just show you driving around. You need to do a log in 3rd gear from 3k to your redline.

[Beemer832]

hahaha you guys are harsh. I am a first time VAG user, (and to save me from putting on the flame suit a second time, I know how to use the OTHER VAG :) )

Anyways, yea so I was just driving around, i didn't realize you needed to be WOT to get anything worth logging. Engine still isn't broken in yet to my satisfaction so I am a few hundred miles from running WOT. I also need to break the clutch in.

Ordering the wideband today as per Jake's and Mike's recommendations...

Put It To The Floor And Log It.
Thats How Your Gonna Drive It So Brake It In Like That!!!!!!!!!!!

[Don Supreme]

No WOT, no CARE!


What tuning are you running?

[Ewok_Fetus]

WOT is good for engine break-in...

[Beemer832]

No WOT, no CARE!


What tuning are you running?

What is CARE? is that an acronym for something or am I reading into that comment too much? lol
and I am running the APR stage 3 tuning. Fueling, tune, maf, injectors, and turbo has NOT changed from when the car was disassembled. The only difference is the rings, pistons, lower compression, and bigger bore.

[Beemer832]

WOT is good for engine break-in...

what about clutch break in? or i guess as long as you dont drop the clutch at like 3k and glaze it over you are ok.. RIGHT?!?!?!


-josh

[k0mpresd]

i didnt want to be the first one to post it. but yea man. rip it out of the gate. if its going to go boom its going to go boom no matter what.

[Ewok_Fetus]

Yes, people will argue that there is a clutch break in, but I don't buy it... Every tranny shop I ask, they say there is no break in... I would go easy for the first 500, but that doesn't mean no WOT... Just don't do a 5k drop from a dead stop or anything...

[dougyfresh]

All you should be doing is driving around in 2nd or 3rd gear and going WOT (foot pedal on the floor) from 2krpm to 5krpm and letting the engine decel on its own. Medium boost (I used the WG spring). Do this for 30miles and change the oil & filter. Rings are broken in. Once the clutch is engaged its fine and you can beat on it.

After 30-50miles, turn up the boost and have fun.


Here are my videos from the first 30miles of my motor. Compression was perfect after 30miles of this.
2nd gear
wastegate (11psi)
93octane
ignore the airbag light and the bulb out light.

[Beemer832]

ok this makes sense. how do i turn my boost down? i am running like 24psi at WOT. i have a gt28r with internal wastegate and the n75 valve and the apr software.

sorry for the noob questions just dont understand the electronic aspect of the apr kit or turbo systems in general. gotta learn somewhere right?

thanks for all the help/info so far.

-josh

[dougyfresh]

I just had my EBC turned off to run off the WG.

I'm pretty sure the poor-man's way is to run a vacuum line from your intake manifold directly to the WG spring solenoid it'll run off the WG. I presume you have a boost gauge to monitor?

[Beemer832]

yes I have a boost gauge and I am assuming run the vacuum line from the intake manifold to the wastegate acctuator on the turbo? again sorry for being dumb...

-josh

[dougyfresh]

Yes, You've got it correct.

[Beemer832]

i think i need a mbc or ebc.... :)


damnit this shit is getting expensive

-josh

[Don Supreme]

^ No you don't, just run the boost source directly to the wastegate (bypassing the n75) and the boost should be limited to the wastegate spring pressure, which will probably be around 8-11 psi.

[Beemer832]

ok that makes sense. so how does this thing run at 24psi? or am i reading/understanding something totally wrong? my boost gauge can hold steady at 24 psi at WOT through all the gears... but if the wastegate has an 11 psi spring, then how does that work?

-josh

-josh

What do you mean? If you run a line like Don Supreme and I suggested the max you will boost is whatever the wastegate spring is set to (11psi for you?). The N75 is the factory, vacuum actuated, boost controller. Your file on the ECu is written for 24psi so the N75 is going to work to get to 24psi. If you bypass the N75 (which is okay) and hook up a line directly to the WG then you'll boost at 11psi. Its fairly straightforward.

Make sure you have Vag-Com hooked up and are monitoring block 020. You may need to pull some timing advance via lemmiwinks if you are seeing high correction factors (CFs).

Follow the procedure I suggested (2000-5000-2000rpm) for 30miles while LOGGING to keep an eye on things. Then change the oil and filter for it'll be full of metal shavings (that's good).

[317ssayzarc]

just hook a vac line from the intake manifold to the wastegate actuator... thats the simplest way i can describe how to control boost for break in

[dougyfresh]

I think we've said that about 3 or 4 times now and for some reason I'm under the impression the OP doesn't understand.

[Beemer832]

k got it. thanks a lot. i was to lazy to pop the headlight out last night to unscrew the hose clamp from the hose on the WG actuator. so... i changed the oil and it looked "good" lots of metal shavings, made the oil look metallic. Change the filter and put some more 5w30 non synthetic oil back in. ran the car again but it was sitll smoking. checked the oil and it seemed to be overfilled??? i only put 4 quarts in but i remember putting like 4.5 quarts in before. i am not sure why the oil doesnt fit???

anyways i am going to drain some oil out tonight and drive the car again but this time i wont be lazy and i will actually hook the vacuum line up. ordering the wideband today, but i don't hear any predetonation in the engine under load. car runs fuckin awesome. i cant wait to run WOT under full boost..:)

thanks
josh

[Don Supreme]

I really hope it stops smoking SOON!!!

Whats your compression looking like?

[Beemer832]

not sure. dont have a long enough compression test gauge. maybe i should stop and get one on the way home. i would rather not FUCK my engine now :) its running way to good. I know i overfilled the oil so it may be blowing past the rings..

-josh

[Don Supreme]

-josh

I don't think over-filling would cause it to blow by the rings, it would probably go out through some auxillary emissions device, pcv or something.

[Ewok_Fetus]

You'd be supprised where oil would go when you overfill... Seen it a bunch... Some tard started filling his oil with the car running... Oil started to pour out of valve cover gaskets, car started to smoke and stumble... I just sat back and laughed... The reason you don't over fill really is to save the cat...

[Beemer832]

no cat here so im not too concerned :)...

ok so now i am under the impression that its the turbo. I had to remove the compressor housing to be able to drill one of the manifold studs out on a drill press. I also stupidly tried to remove the exhaust side of the turbo from the middle "core" piece. it would not seperate so i just bolted it back togehter.. I am wondering if i fucked up the seals or something stupid. so new question, is it bad to run a blown turbo if its just spitting oil?...

-josh

[Don Supreme]

A turbo with a bad turbine side seal could probably damage:

1. The turbo
2. Cat
3. Maybe o2 sensors
4. YOUR ENTIRE ENGINE, IF YOU RUN OUT OF OIL - :->

[Beemer832]

just spoke with ATP, used them as a resource. basically said to damage a dual ball bearing turbo is pretty impossible. im starting to think i might have a leaky valve guide seal or something like that... maybe its time to look at a worked QED head? :) i could use a safer rev limit for the gt3071's top end :)

-josh

[dougyfresh]

Is the smoke coming out the exhaust or can you see it with the car idling and the hood open? In other words, are you just burning off excess oil that is on the outside of the engine or are you physically burning the oil in your combustion chamber and out the exhaust?

Why did you overfill the engine when you changed the oil last?

Have you looked at your spark plugs? What do they look like? Color?

Have you done a once-over visual of your engine compartment to make sure nothing is leaking anywhere? Coolant lines, oil system, all lines on the turbo, etc...

smoke is coming out of the exhaust. there was SOME excess oil burning on the engine and the engine paint was baking on, but its VERY evident on the smoke coming from the exhaust.

i didn intentionally overfill the engine with oil. I remember the enginet aking 4.5 quarts of oil so i dumped 4 quarts in and checked the level and it was already overfilled?? weird.

i am going to pull the spark plugs tonight to check color and see if there is any oil on them. i replaced these plugs when the engine went in so i don't know if they will be colored yet.

i have checked the engine bay over and over. had a small coolant leak at the turbo that has been fixed. all other lines and hoses are not leaking. there was some spill from the coolant take when i missed the funnel but other then that i am dry as a bone.

-josh

[Beemer832]

smoking is getting worse. starting to think its a valve guide seal. this fuckin blows....
