Hello there again! I have been experimenting with a lot of different tweaks in my BIN. But i can't seem to get the result i am looking for. (Worth noting, i have a catless downpipe, and a milltek resonated exhaust which consists of 2 mufflers) What i want is consistent pops and bangs on lift off, right now i can only get the result i want when revving to redline (6800RPM). It also seems to pop very softly when revved up to 2k rpm. Above this value it doesn't seem to do anything while standing still. For example, i'd like something like this following video. https://www.youtube.com/watch?v=xxKmNkRWzFgMy starting point is KFZWMN -50 on the lowest three rows up from 1480RPM. I have played around with KFZW and KFZWOP even negative KFZWOP but none seem to give me the result i'd really like. Also it seems messing with KFZW and KFZWOP messes with the engine more than i'd like, when X - 30 on KFZW and X - 20 on KFZWOP along with the KFZWMN changes it shifts pretty bad while accelerating and changing gears up. KFTSVA is set to 2.5 from 20.25 and above. I'd like to try CWSAWE but the XDF i'm using doesn't have it and i'm not sure on how to find it. I'm not even sure if i really need it. Also i'd like to fiddle around with KFTSRL for a hard limiter. Is there perhaps anyone who could help me out or point me in the direction to accurately find these values? If this is not my problem, what else could i try for some consistent pops and bangs? |

cwsawe 0x11211
As for another its million times answered in bangs thread
kfzwop sub 20
kfzwmn to ~ -20
kftvsakat
read FR
do the logs to spot the problem not blindly tune it
p.s most of changes in that file are... weird

Thanks for the quick reply! I have tried a lot of different combinations but for now none seemed to give me the result i'd be after. I certainly agree on logging, but i figured a lot of people have had succes with some easy changes. I have also logged but only using VCDS to confirm boost pressures, load, and ignition timing angles. Also, i don't have KFTVSAKAT could you help me with this one aswell? I have tried comparing a few XDF's but none seemed to make sense for my BIN, or they were less defined than the 032DR i already use. What changes do you consider weird? I'd like to look into these and perhaps try better ones instead. |

I sadly do not have a winOLS copy, only a demo version. Neither does it seem i can extract the adresses in any way because it doesn't accept my modified BINs. Thank you anyways! |

you can import mappacks in demo version and just take the addresses from the .kp and port them to your xdf also your bin has rights provoked in winols ( at least for me) so what is so special about it |

Thanks by the way, didn't know that. Its the original read from my car, if you inspect the file in hex you can see in the last non empty row it has some crappy no-read protection. |

After some further testing i now have;
KFZWMN to -48 lowest 3 rows starting at 1480RPM
KFZWOP X-20 lowest 2 rows starting from 1240RPM
KFZW unchanged, this made the engine perform poorly when shifting.
KFTVSA 20.25 and higher is set to 2.5s
CWSAWE is changed to 1 but i'm not quite sure if it makes any difference, as of now it seems not.
And i am now stuck, as i am able to get very good pops when lifting off in first gear and only in first gear at any set RPM. Any other gear doesn't even pop slightly as much as first.. the only other way to get a good result is when revving to redline.
What is it that i am missing? Im willing to try negative KFZWOP but i figured its probably best not to.
I've seen people also get results with KFNWEGM but i'd rather stick to using KFTVSA as it seems safer to do so.

KFZWMN to -48 lowest 3 rows starting at 1480RPM. Uploaded file has -39.75
KFZWOP X-20 lowest 2 rows starting from 1240RPM. Not true.
CWSAWE is changed to 1 but i'm not quite sure if it makes any difference, as of now it seems not. Not true.
Also part number is changed to DE, but is DR 0003. Also NOREAD tag is on, not sure why. Changes are super weird and don't make much sense. I don't believe your definitions are correct. |

Okay i'll try using the nefmoto logger again today if i can spot anything odd. |

Use ME7Logger, not nef. |

The things i have changed i believe to be correct, since i compared them to others. I am not sure about the changed part number, the original ECU says 032DE on the casing. I am using 032DR XDF on an 032DE file. I believe they are from @fukenbroken. Values i've checked all add up, so i figured the data structure would be the same in both files. I took this file as a starting point since there wasn't messed around with checksums or any checks. I'd really like to know what changes are weird, why are they and what can be done to improve them. I have read the S4 wiki and am trying to understand as much as possible, but as a noob i figured the car runs good so why bother messing around with things i know little about. I'd really like to know how to do it better, is there any specific thread i should look at? |

Hello again!
I have played around with KFZWOP, and found that using -20 on the lowest two load rows gives me extremely hard bangs, along with -48 on KFZWMN. It now works as expected but i was just using these extremes to test. I'll bring them down eventually. I also think that i need more extreme values because my milltek exhaust system is too restrictive.
As suggested to me before, i will start on my own tune from scratch. And learn it the proper way, right now i've simply modified my existing "stage 2" tune. But as a few have mentioned it has some weird changes and thus i'm willing to start from scratch.
After reading some topics on the forum i've figured going with a MAF would be best. I still would like to know what gain there is to not running a MAF sensor, otherwise why would anyone do this? In the coming weeks i hope to pick up a MAF sensor somewhere, modify my intake piping to fit it and perhaps swap out the K03s for a BAM K04 023.
Also; is there perhaps anyone who can shed some more light on fault code P0130. When checking the lambda its all over the place, and i don't think the sensor itself is at fault because it has been replaced with a genuine bosch unit.

Stop saying "no MAF sensor" and instead say "alpha-n" or "speed-density". Anyone NOT running a MAF who doesn't know the difference has absolutely no business telling anyone what is so wonderful about running "MAFless". They're mostly fucking retards. |
