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.
