Pedal Commander for BMW 8 Series

Was skeptical it would make a real difference on my 840i, but the throttle response is noticeably sharper in city traffic now. The plug-and-play install took me under an hour, and the app lets me dial it back to stock in two seconds if my wife drives it.

Installed this on my M850i last weekend, and the throttle response difference in Sport+ mode is immediate. The four adjustment modes let me dial in exactly how sharp I want the pedal feel for daily driving versus spirited backroads.

Took a bit longer to install than the instructions suggested, but once I had it dialed in, the throttle response in Sport+ mode on my 840i is noticeably sharper. The 4 adjustment modes give you plenty of room to find the right feel. Good upgrade for the money.
