Update: I'm ready too start this stage 1 tune thread but I have one problem! I cant seem to find my system to lean off idle problem! I've logged and everything. Pressure tested/smoked the whole system, cam follower was inspected, pcv is new, maf is fine/unplugged to see if that was the cause. Diverter valve is brand new, last one failed. I've done it all except changed high pressure fuel pump or fuel filter. I don't swap parts until I verified they are bad. What are your guy's thoughts? I was to start tuning it but I cant without it being properly running.
Also rail pressure is 4-5 bar high pressure side follows requested.

Put the stock intake system back on. Doing a community tune thread, you'd want that stock anyway.

Yes try the stock intake.

Sad part is I bought it with the aftermarket intake. Does anybody have an extra intake around? I'll pay shipping.

Here is a map of all the maps in the stage one. Except the fueling safety maps were giving me problems. Can someone correct it for me? Thanks.

Please show your fuel trims?

My idle adaptation is .6% and my ltft is 21% I'll post logs when I get home. Hpfp follow requested.

I have ltft as well on stock file, and stock intake, changed everything beside g247 and I am doing lpfp and fuel filter this weekend, already did the hpfp and still have trim up in the 20%

I wonder if it's the module or lpfp itself? Can you get back to us after the lpfp install. It's the only thing left it could be.

well i was unable to do the lpfp as the lock ring was pretty rusty so i'm going to order other one before i do it i did get the fuel filter replaced and i am still getting ltft above 20%

Thanks for the update.

I'm almost thinking it may be because my software and epprom isn't the correct one, my ecu is a 7115b 010 file and the file im using is a stock 7115h 030 file, I will know tomorrow when I receive my bdm reader and I'm going to need to immo off my stage 1+ untrionic ecu that was the car oem before I got the dealer to do a  ecu swap, when I use the stock 7115b I can a error in group 60 tba

I actually used another eeprom and bin file to verify this. No change. I am dead set on this lpfp. It's the only thing left.

You thinking it's more of my lpfp then anything?

I could be wrong but after verifying everything what else could it be? Other than the module it's self possibly. The one being the drivers seat I believe. But I think it's the pump. Anybody else have a say in this?

I dont know, But i have LPFP controller if it helps. Its used from a 2.0t passat.
If ya'll got a part number i can check it.

Where are you located? Im in Canada and I am replacing lpfp tomorrow, do you think also not running right softwaremake a issue?

I've swapped software and it didn't change my ltft, it did mess with my rpms hanging and obviously traction control ect.. I'm in Michigan, so atleast our climate is close to the same.

Can you pm me please and yes that's true we are very close, my bdm reader is in just gotta open my ecu that has my unitronic stage 1+ tune to immo off it and then going to check my ltft because before I got the dealer to do the ecu swap my car worked good, did the swap thenflashed someone tune, and the software didn't match my software. Going to clone the epprom I'm hoping if it's able to be done along with saving the tune file that's already on it

I know the 7115b the dealer swapped for my the rpm were hanging and traction control was disable but when I reflash it now I can't rev over 2000 rpm and ny TBA error out, but the 7115h works but get ltft

Cross flashing these ecus is not a good idea. 

As a test, I cross flashed a 115B onto a car that originally came with 115P.  The car drove fine, but the partial (multiplicative) trims continued to rise while cruising.  Light cruising, no boost.  I then scrapped using 115B and used 115P and everything is good.

Based on the little research I did on the subject, I believe there was a change in the hpfp cam follower between those years, 4 small lobes vs 1 big lobe and I assume that was the difference.

The fix is to always use the correct version software.

All EA113 TFSI engines run a 3 lobe HPFP setup on the inlet cam. There have been different revisions of camshaft, follower and pump, but the fundamental design is the same from 2004-2013.

Any idea why partial fuel trims go crazy when running a 115B from a 06 a3 on a 07 a3 (115P)?  Again, in my experience, it was just cruising that was causing an increase in the partial trim.

For informational purposes, I am using the stock ecu that came in the car. The medal lock out tabs were still there. So nobody has messed with this car.

URGHHHHH!!! This car is not giving up! Fuel pump is replaced and fuel trims are still through the roof off idle (22%). Is it possible to install incorrect high pressure fuel pump? Were the hpfp the same 06 to 2013?

Pretty much identical.

Log channels 230 and 231. Check rail pressures. Stock car should idle around 50-60bar, and 110bar on WOT. LPFP should be between 3.5-6bar depending on load. If those are in spec, there's nothing wrong with fuel delivery.

Check your dipstick. There's an o-ring at the top that is known to perish and fall inside the sump. If that's gone, it could be drawing air on idle. I strongly suspect drawing in air is the result of your trims.

Logged and high pressure follows requested, low side was 5 bar. Dipstick tube is all good, but I did find something. The check valve for the pcv. When I perform a boost leak test, I disconnect the pcv from the valve cover. I then plug the open port on the valve cover. I apply pressure to the system and the check valve that connects to the turbo leaks after 2-4 psi. I understand the valve is suppose to be under vaccum but I should still spot positive pressure correct? Can someone verify this?

For my issus with the ltft is still there changed everything and got a 6.6 bars fuel filter hpfp lpfp cam follower 02bank1 maf but I am running 7115h on a 7115b ecu you say a 7115p worked for you, I can't go back to stock 7115b the dealer did the ecu flash with out getting a tba I'm waiting on bdm100 to immo off my ori ecu that came with the car. 

So I end up clicking on a wrong file and flashed it to my car smh immo active now I'm at the vw dealer and I'm getting the right flash for my car and then I hope it will fix the ltft I'll update when I get my car back so i got bad news from the dealer saying my immo is locked for 24 hours and will have to try to reflash tomorrow will keep it updated

4 pages, and not even 1 single stock log posted yet. This thread is turning into a "fix the hardware issues on my 2.0T thread".  ::)

For informational purposes, just because the metal locking tabs are there doesn't mean the ecu wasn't "messed with"

1. It could have been flashed via OBD. A Revo trial could be on there for all you know. Seen it.
2. Someone could have reinstalled the tamper proof screws. You can buy them new from any dealership.

Changed everything?

Pop the cover off, and see if the diaphragm is torn. You can buy a replacement from your local Napa on the cheap.

I have stock file 7115h file logs but unsure of how to upload, once I get my car back from the dealer tonight I'm hoping since they said the key adopting is unavailable for 24 hours because it was over the 3 tires when I try to flash back to a good file, live and learn I guess lol. I'm sure the dealer will put 7115B back on my ecu and I'll do more logs and hope my ltft is good instead of hitting 25% dealer told me.my problem is software issue not anything else

When stating what file you're using, it's helpful to also know the revision, and the full part number. Also doing a full read and making sure it is in fact 100% stock wouldn't be a bad idea either. Simply saying "7115h" isn't telling the whole story. Imagine someone else following this thread with less experience/ knowledge trying to figure things out. This is after all supposed to be a community thread, right?

I will update with all the info when I'm home as I do not have the PC that has that info all on there. I have a question do you real bdm100 or the clone? Or something different to read EPROM? I only have a MPPs cable

You need to use BDM to read the e2p. Genuine or clone will work. Clones are buggy, and unreliable/ risky to use.

This is FSI, i thought you had to buy the whole breather, i can only get the dia for tsi and 2.5

There's a diaphragm in the valve cover on a fsi engine?

Sorry I didn't intend for this to be the case.

Don't apologize, just start another thread for your hardware issues. It would have been nice to see in the first page...

1. What file we're working with, with the original posted.
2. Some stock logs of cars without issues.3-5 different cars would be good to get an average. I remember in the B5S4 thread towards the end everyone figured out their N75's were adjusted differently, so they all got different boost response using the same file.
3. A paragraph or two outlining the goals of the thread, and any special concerns with the hardware. Differences between MED9 and ME7.

Just trying to give you guys some direction. I think this thread is a good idea, and I wish I had more time to provide info, and contribute overall, but unfortunately I'm buried at the moment.

Adjusted differently?  N75's don't have an adjustment as far as I know, they just get old, worn and sticky.  I could be wrong, but I just never noticed an adjustment.  And I just googled it and goddamn... there's an adjustment screw.  :)

To the point, it might be wise to abandon/rename this thread and create a new community thread with the suggestions made above.

I think it would be best to delete this thread and start fresh, the purpose was to get stock logs but when I went to get stock logs I found a big problem. This running lean problem under load only, which has been a hell of a problem.
To update everybody so they can see what has been done so far and hasn't resolve my problem.
Parts replaced
pcv system, the front pcv that connects the the valve cover/ plus the rear pcv check valve
Fuel filter
fuel pump
cam follower
coil packs
spark plugs
o2 sensor
diverter valve
smoke tested/pressure tested the whole system

Parts that haven't been replaced
high pressure fuel pump (high pressure follows requested)
Fuel injectors
fuel pump module

The logs taken are of the car having this issue. I've unplugged the maf to eliminated possible intake leaks, I've even checked o ring on map sensor to make sure all is still there.

There's an adjustment screw if you look closely.

It says this in the text you just quoted...

 "And I just googled it and goddamn... there's an adjustment screw."

You guys need to slow down. Lol

Split topic.

Can we not do this dance again?

Stay on topic. Don't give me work to do geez.

Just trying to keep you on your toes ;D
Thanks for fixing the cluster
