[Wires]

I've did some playing over the last couple weeks to try to clarify the driving modes. I have a 2016 BMW 340xi, and I've attached a table of how they work on my car. I drive in manual / sport mode all the time, so I have no comment about when the transmission shifts in pure auto mode, or which modes inhibit 8th gear.

The other E90 / F30 tables do not match my vehicle. Attached in case others where wondering what they do. Only real change in sport+ that I can see is the exhaust valve on the left tip is open all the time, and DTC turns off. With it off, and on dry pavement, I can slip the rear out under hard cornering / acceleration, as well as the car allows wheel slip during gear changes so the car accelerates like a demon (with the expense of some rubber).
