Used MDM for the first time
So I've driven my F80 for about 14k miles with all the safety nannies on. I've driven it in sport modes about 30-40% of the time.
Today afternoon I decided to check out this MDM mode. Holy hell- it's like a completely different car! The acceleration is so much more responsive! Makes me fall in love with the F80 all over again. Of course, I know my limits as a driver, so I promptly got out of MDM and put DSC back on. But getting a taste of what it can truly do unchained put a smile on my face! |

I've had mine just a few weeks. Need some dry pavement and then I'll give this ago. When I row the gears I can feel something that feels like a micro flattening of the torque curve. I'm guessing that's the TC cutting in.

What you are feeling is definitely the TC reining in the car. |

If you don't understand this, then you will never be able to effectively control the car yourself with DSC off. If you really want to learn how to control your M3, sign up for an autocross. Run the first session with DSC on, the second session in MDM mode, and the third session with DSC off. You will be humbled.

Even in MDM, the car is quite bridled. So no, it is far from being "unchained" in MDM . You need DSC fully off for that, but do so at your own risk (not recommended unless you have the proper driving skills).

In a straight line, with the DSC fully off, at what speed will it break the tires lose?
I've never had a car with this much power. I'm really liking it. I've ridden, own and owned fast motorcycles, but this is the best acceleration I've owned with a cage around me. Had a couple turbo charged 350hp Mitsus and a V8 S4 (all AWD), but this is whole different beast. Need to do a track day. |

I've heard the euro mdm is perfect for that middle ground.

MDM allows enough slip to make you smile, but not so much that you become a light pole ornament.

You want to know what chaos feels like? DSC off in the rain.

I did a couple Autocross laps on wet pavement after a guy spilled oil on the course. With TC completely off, it was practically un-driveable. Wheel spin city. With MDM, I really felt it intervene to stop the wheel spin. It was pretty impressive. The only time I "liked" my MDM mode.

DSC does indeed limit the car's abilities by reining the car. It is tuned very conservatively for safety and will make interventions before an actual loss of traction occurs. This is also true in MDM, but to a much lesser extent.

I had a '16 F80 prior to my CS, and I can confirm that the MDM on the CS is a lot more fun and loose. It kind of took me by surprise at first! The rear end kicked out so fast that I thought I had completely switched DSC off! It has a nice progressive recovery though, quite enjoyable and a bit nerve racking for passengers!
