Wii Classic Controller Range

[Miinee]

I'm trying to play Xenoblade Chronicles and I ran into a small "convenience" issue. I'm playing using the emulated wiimote with the classic controller extension and I set the right stick to respond to mouse movement (axis x/y). The problem is that the camera rotates extremely slowly when moving the mouse. So I increased the range to 500 and it got better but still too slow. I've tried to increase it manually by editing the config file but ingame doesn't change. Is there anyway to increase this parameter?
