Hey!

I'm hoping someone can take a look for me at these files, as i'm obviously doing something extremely wrong here. I know how to log using ME7logger but already using VCDS i can see i'm running extremely lean for whatever reason on idle and part throttle (even throwing missfire codes & lean codes). WOT actually appears to be fine, lambda values look good. I already flashed back to a known working file after 1 small drive.

I understand the need for logs, but i don't feel comfortable running this again as i'm doing something very wrong but i can't point my finger at what. Every change I made seems valid, and the only fuelling changes made are in KRKTE and LAMFA. One moment it runs well, the other moment it is too lean. What could cause this? On part throttle it missfires, stutters and what not. I haven't even changed anything regarding small load so i don't understand.

Requested and specified boost looks spot on, around 1.4bar (as planned). Car is ran on RON98 fuel exclusively so I believe aiming for around ~12.2AFR at WOT makes sense.

This is a tune I completely made by myself, there is nothing copied over from other tunes. It's also probably an extremely noob mistake i'm overseeing here.

Attached is my own version, stock and XDF. Car has no faults, using the file it came with or stock it runs perfect. I've also ran a basic 'stage 1' changed file (made by myself) which also has no problems.

If it still is of use to log this file, please let me know and i will get right to it.

No hardware problem. Engine runs well on known working file which came on the car (it is a badly tuned stg2 file).

Fuelling must be around its max. It's 317cc injectors @ 4 bar. I could check injector DC. From what i can tell looking at VCDS it really appears to be random lean spots for whatever reason. WOT looks good, idle sometimes good other minute way to lean same for cruise/slow accelerating load. Slowly accelerating also comes with missfires but not every time.
