Ok thanks guys, now i kinda got it. Of course setting it for the cruise control would be the better way and I've hacked programs (actually games) with ASM on my computer some time ago already (beginner steps tho).

But I dont understand exactly in which code you have to make these changes for the cruise control? in the ECU .bin dump!? That doesn't really make sense bc it only contains maps or not?

And where do you jump to after? To own code in code cave which u have to program?
And how can you test your code without killing the ECU by flashing maybe bad code?^^ because I'm noob and only understand it kinda theoretically.

I'd like to look on the code of cruise control myself in ASM but I dont really know where to search lol.
My second problem is for my car there's no DAMOS on the web so I have to search everything myself!

Thanks a lot tho will try to figure it out with A/C first! But yea I'll need the other map changes too so the only real way would be cruise control I guess for it to pop.

some example to look at (in a youtube video or something) would make it a LOT easier if there's something out in the internet.

I'm ofc not a chip tuner and just want to get it done on my car also I'd like to fit in a WOT BOX in combination so it would be nice if I can simulate clutch presses while shifting (automatic) that's why I'm trying to play a bit with the code Maybe it's not too hard to get it done!

Edit: Another thing not quite clear to me: if I make changes to KFZWMN and KFZWOP, do they affect normal driving also and could cause possible damage in long term or are there maps that are ONLY active for overrun? Because in KFZWMN the min limits for iginiting are set, so could anything go wrong possibly if i modify it while driving "normal"? I guess best for the engine would be to only use modified maps when cruise control is pressed so i guess I'll have to mess with it till i get that done guess that would be best for long term !?

Do you think there is an option to make this work sort of in reverse? All i could come up with is putting a negative value, but i don't think that can fit in 1 byte.
