Hello together, is the flap in the exhaust in the Sport+ mode DUERHAFT open, or does this still adjust to speed etc. and opens only partially? If that were so, so permanently open, then manual flap controls like ASR etc would be completely meaningless. Operating permission goes flute for nothing and they do nothing else than the SPORT+ mode. Does anyone have a m850 (cabrio) and a manual flap control installed? Has the sound improved thereby? If in the Sport+ mode the Kl I have my 850er convertible now since July and I miss my Mustang GT 5.0 more and more. That was a sound, I had to grin every time I drive. In the BMW with 530 hp I always catch myself as I push on Sport+ and switch to something to hear… an absolute shame. As wonderful as the car drives itself and no matter how beautiful the look, without sound the nic ht my (dream) car. Has anyone found a halfway legal way to optimize the sound experience?
