Can anyone tell me what iam doing wrong?
Changed KFZW and KFZW2 map first 2 rows from about 4600 rpm to 6000 to a value of -18 to -8. This works on my 1.8t but on the 1.4 it doesn't work. It makes very small pops. Do i have to edit fuelcut maybe?
Who can help me?

There are tons of information about this but somehow people still research a fucking ridiculous ways to do that
Do logs

Search the thread: "Overrun, Flames, Gargle, Pop" its got tons of Info.
It looks long but trust me its worth it. Generally I think first 4 pages you will find what you need for your particular ECU.

It worked on my 1.8T with changing kfzwmn and kfwzop to -18 and leaving kfwz alone.

leaving kfwz alone.

This is not a good idea, and discussed at length.

hello,

i did read this entire topic but from what i also learned a lot of users didnt change kfzw.  infact when i changed all timing maps (for pops and bangs) car didnt drowe smooth under really low load , when setting back kfwz to original this efect was gone.

Check the axis values, as you might be interfering on too high loads such as 30%+ i made this mistake too once.

I didn't change KFZW on 1.8T
Try negative values on KFZWMN such as -20, -30.
I suppose the car also has KFZWOP map, recommended is current value minus 20. But i tried with negative values such as -10, -20 for hard bangs.
Use KFTVSA to delay fuel cut.
