Thank you, that it is. But now i have some sort of protection. After 1.5 second fuel cut come in(it is set to 2.5 sec), and my iginion start to follow zwmnnms. Then again it goes to low values
This could be a engine protection  B_zwms, but I can't see how to turn it off, maybe KFZWMS?

Edit: i changed KFZWMS, now ignition stays at -24, but fuel cut come in too soon

go to FR and check review the BBSAWE function.

Hint (not sure if it will solve: check KFTVSA KFTVSAKAT TVSAG0 TVSABTE)

I will do more digining. It is not connected to seconds, somethnig else control fuel cut.
These are two logs
One after 3 gr. wot, and one after 6 gear run

I think once it gets to lambda=1 then ignition follows another path.

Ok, I've read whole topic, but I still need an advice Sad
I want to reach something like this https://www.youtube.com/watch?v=VWH3pkD5Ru4 (it hasn't to be that agressive as the loudest one, but something like that, still don't want to flame from pipes).
In a few words, I want gargles on engine deaccerelation (without pressing clutch) Smiley
I'm still not sure what should I have change in maps. As far as it is MED 9.1 (2.0TFSI BWA) I think about settings like on the picture.
KFZWOP 10% row "value - 20", 15% row "value - 10".
I wonder to change CWSAWE to 1 (to use gargles without pressing clutch), or I should do not that?
Or maybe use ENSAKHG set to 63 like @KasperH did it?

okay so can we come to a conclusion as to what ENSAKHG is?
google translate has two definitions depending on if you put a space between katheizen. first definition is without space between kat and heizen second is with space.
1. Enable overrun shutdown during cathexis dependent on gear
2. Release Thrust shutdown in the case of catalytic heating
also how is it determined as to what value to set this at?
ENSAKHG exists in the Mbox damos address 11171

1) there is no universe where Kat heizen is anything but cat heating
2) did you bother check the FR? The bits are pretty explicitly explained there.

Well, I won't touch ENSAKHG as far as I won't be sure what EXACTLY it does Wink.
Anyway, I've changed maps like on my picture above + I've changed CWSAWE. I just got 1, max 2 single pops when I let off throttle, but never on gear change, only when decelerating (and not always), when standing it does suprising 3 pops Cheesy.
I was wondering about reduce KFZWMN to -17deg, change KFTVSA to 3.5. I don't want to make large pops, bangs or flames, I just want gargles. (And maybe rescale LAMFA 50% to 10% and make something like 0.9 LAMBDA for this value, should I?)
Is my thinking in a good way or I should do more to get  gargles on MED9.1?

any retardation on the timing map produces a nice deep bang on gear shifts and obnoxious popping on decel depending at which rpm you have it at

my issue is since the timing is retarded, the car jutters when going back onto throttle. yet to solve that issue

This probably the cause of the fluctuation between the advance and the retardation of the ignition. Log ignition to see what it does at going back on throttle.

that is exactly what it is doing. i knew this but felt it wasn't healthy so i just disabled the whole timing retardation deal for overrun

Hi, can someone tell me the maps for ME7.5 512 kb. These ECU do not have all the maps that you decide regarding the MED or ME7.5 1024kb.

are we supposed to guess what ecu you have?
