Title: A4 B6 1.8T K04-15 Returnless Closing throttle after 150g/s Post by: error1997 on November 12, 2019, 12:07:54 AM Hello, all
Firstly I would like to appogise for the vagcom logs and cracked ols ;D . Recently I tried to tune k04-15 but ran into the issue of closing throttle . Of course I read all the topics about the same problem but all of them had severe overboost . Mine doesn't , at least from what I can tell from the logs . I tried stupid things like modifying KFWDKMSN and its inverse but to nobodies surprise it did not help . Also tried maxing KFLDHBN , KFDLULS and zeroing correction from KFTARX , again no results . The only correlation that I think I have found is that after 150g/s the throttle closes , does not depend on rpm , iat or boost . I may be wrong though . Logs and ols attached below , any help would be appreciated Title: Re: A4 B6 1.8T K04-15 Returnless Closing throttle after 150g/s Post by: BlackT on November 12, 2019, 12:30:35 AM Bad tuned KFMIRL and KFMIOP

I use excel to calculate KFMIOP to be inverse of KFMIRL , and it is correctly working (calculated KFMIOP from a stock file has a percent difference below 1% for the most part , pic attached below) . Also the request of load in KFMIRL is high enough . Lol never saw 120c iat before Bad dyno cooling FTW Title: Re: A4 B6 1.8T K04-15 Returnless Closing throttle after 150g/s Post by: soul87 on November 12, 2019, 02:49:25 AM what was the reason of editing
KFWDKMSN KFMSNWDK KFDMDARO KFDMDAROS KFDMDADP ??? KFMIOP and KFMIRL looks good.

KFMIOP and KFMIRL looks good. Desperate times require desperate measures or in other words I had wrong understanding of them .

Is that file from first post your stock file, or the file you are using right now? As I can see from this poor VCDS log, there is a tourqe invertion, what is often caused by bad tuned KFMIRL and KFMIOP Title: Re: A4 B6 1.8T K04-15 Returnless Closing throttle after 150g/s Post by: soul87 on November 12, 2019, 04:30:39 AM Revert back to stock not needed maps. Flash it, send me the file that You flashed and send me the logs, (You can send it by PW - VCDS logs for me are ok )

Version 8 is for LOG-110-114-2 Why don't you use Me7logger? The car is at a another town , and I use a friend to flash and log it , did not bother to explain me7logger to him , though vcds would be enough for tune for k04 Title: Re: A4 B6 1.8T K04-15 Returnless Closing throttle after 150g/s Post by: nyet on November 12, 2019, 08:29:22 AM though vcds would be enough for tune for k04 It isn't.
