I thought it was full open with the bluetooth controller.
Traction mode would be much louder if the left valve stays open I think.

Thanks!
The car mode has no control over the exhaust flaps on the MPE. The mode change effect the fuel mapping, shift modes, etc....
At idle with flaps open when i rev it in comfort vs sport there is a big change in burbles..... not so much between sport and sport +. Same as when I am driving
