DSC: M-Dynamic Mode

[13eastie]

Owners,

Has anyone found any drawbacks at all of MDM Mode? In my experience it feels very safe and offers far better cornering and acceleration. Normal DSC, on the other hand, seems sensitive to the degree of intrusion.

I could not have lived without it now that I'm running on soft winter tires.
Normal DSC interfere at the least push of the throttle, while MDM mode lets the wheels slip just enough to keep the fun going - with as much traction as possible. Quite impressive actually.

My first experience with MDM was at the Nürburgring event, at the end we decided to find out just how good it really was and gave full throttle through a rather long bend that got sharper towards the end. MDM mode kept the understeer surprisingly well in check through the whole corner.
Unfortunately BMW did not let us turn MDM entirely off, which made me unable to compare the modes on track. Obviously I have not pushed the car to its limits on public roads.

Well, one of the days when we actually had snow here in Stockholm I went out for some awesome fun drifting (in low speeds) and I found that MDM wouldn't let me go completely sideways when I wanted. So I ended off having my fun without it on.

On a normal day (during winter this is), it allows you to loose grip but then just as easy regain it when ever you choose, not a second before it's your own personal choice. Absolutely wonderful, allthough I've found that when doing 0-whatever from a red light I hardly get anywhere fast at all with MDM on. DSC on is going sooo much faster.

Please take in regard that this is according to the Swedish winter climates, where we have between +4c and -4c every day (it's a warm winter).

Thats quite different from Tiff Needle's demonstration in his M3 test on Fifth Gear which showed MDM far superior to DSC ON. This was on dry tarmac however.

Yes, and all I've been saying is that on wet/icy/snowy surfaces I prefere DSC ON for safety and DSC off for when going totally sideways and MDM on for looking like a hero while still playing it safe (but unable to go totally sideways).

I am yet to try this in dry conditions which I can't wait for!

I can't say that I have noticed the regular DSC intervene at all, but I have probably been driving conservatively in this mode anyway. Is there a dash light that indicates when it activates?

As for MDM, I would agree that it does feel very safe. We have a few roads paved in concrete rather than tarmac near us and I have had the tail end out a little around some of these corners in MD Mode, but it has always felt very controlled. After my run-in service a few days ago, I put it in MDM to leave the dealership and got a little wheel spin for the first time

There is. It's a yellow light with a warning triangle inside a circle.

Wonderful feeling, isn't it!?

Just a suggestion, but if you aren't/weren't aware of how the DSC works, there's probably many other things you may be missing. Might want to go over the manual.

[OzStriker]

Ahhhhhhh the DSC light

Chris Wilson on a wet Nurburgring:

"The little yellow light on the dashboard is dancing away quite merrily"

Thanks, good suggestion. Problem is whenever I I get rapidly side tracked by a desire to

[nusevad]

I think i would probably end up carrying the manual everywhere i go for the first week. Its going to make great bathroom reading material!

Not my experience at all - acceleration from standing (subjectively) is far better with MDM. (And you get an extra light on the dash too)

MDM mode sounds like DTC mode in the 335i? There was confusion on the 335i boards, and testing has proven that DTC ON (press DSC button once, light and wearning appear in dashboard which some confuse as DTC off) is generally the hot ticket for best acceleration and "safe" play on the track. DSC completely off is for experts/no walls/no worries at the track. DSC completely on is for everyday driving or "most" safe mode, though some expert drivers complain that DSC interrupted their own corrections when playing and actually is less safe than completely off.

I always run around in DTC ON, which I think is a version of MDM, though probably less aggressive in what is allowed in corners.

At least on the M5 / M6, MDM kicks in much later than DSC ON. Can't give you the conditions but I was beating around an M5 / M6 at M School and the little secret that I had was I was driving around with MDM when we were told to keep DSC on.

For a big chunk of the weekend, it was raining and I found DSC way too instusive in the wet and dry.... MDM gave much more latittude but it wasn't crazy like DSC OFF. In the drifting exercise, the M5 needed DSC OFF to drift (it was surprising easier to drift than the Z4M). In the road sections of the course, with MDM you could carry a little drift angle on track out that you couldn't with DSC on.

In tracking my own M6, same experience (no wet experience in my own car)..... lots more latittude on track out....

One thing you guys need to remember, I am not concerned about losing control or the car sliding as much as I am about the car cutting power..... When the car cuts power, it is extremely disrupting.


One final comment: Car control is a lost art. My old race car, no traction control, no ABS. People rely on electronics to stay on the track so when they think they have the skills and seattime to turn of DSC, they are in the wall.

Yes. DTC "on" is the same principle as MDM (M Dynamic mode).

I fully agree with all that you are saying. The only thing is that DSC on = it cuts the power the second you loose traction. You won't be able to drift, slide loose control or anything. MDM is a middle thing, but you can always get back to safty by releasing the gas pedal. And OFF is like on every car... You can spin out of control.

Here's me doing it with DSC: MDM
It wasn't as slippery as for which my previous comments where regarding, which allowed for a nice start.

How do I embed it?

Do you need to purchase the technology package to get m dynamic mode? is that part of the EDC or is this standard on the m3?
thanks

you need the Tech package.

[m0n0x!de]

No! i haven't found one drawback yet! I'm still searching...
