So I'm new to the tuning scene and managed to get myself a kess v2 clone I did pop and bang at my friends mk5 gti with the same software as mine controlled by the ac button and it works fine, my problem is that my ac doesn't work, so the map doesn't work without working ac. I have also seen some mk5 gtis which can control their pop and bang on the rear window heating button, but I don't have any clue how to do that can someone help me out with it?

I don`t know if i made something wrong or it is a bad mapping but the pop and bang tune on a Med9.1 is not that difficult, for me it works and if i made sth. wrong feel free to correct me !

so i changed :

KFTVSA to 2.555 (max)
DNWEK to 6000 or 7000
TVSAG0 to 3 sec
KFZWM... depending on which hardness you want it and which hardare your running like catless or sports cat you can change from -22.5 to -35 at an rpm range about 2000 to 7000 or whatever you want to.
correct the checksum and flash to the ecu, thats one way i know how to do pop and bang.
