M-Dynamic mode of DSC, does it learn? (e90 M3)

[-Z-]

Had the car for a few weeks now, love the M-Dynamic mode with its oversteer happy tendencies.

I'm probably wrong but I'm sure its allowing greater angles for longer than when I first got it?

I don't think the MDM is adaptative but I understand what you mean, my understanding is that you know the car better and better and slide it probably more smoothly so that the computer comparing the throttle and steering wheel inputs with the Gmeters let your car be more wide.
During a trip in the Alps, after a few days of everyday "sport" driving I (or the MDM of the car ) was able to induce long but not violent slides at exit of hairpins

So do you think MDM actually helps you drift, by comparison with having DSC off? The only time I tried (on proving ground, I am not skilled enough to turn DSC off on the road) I found that even in MDM the system cut the throttle viciously, and it was too long before it gave me the power back - so I turned DSC off. I'm going to Bruntingthorpe later this month, so I will play again.

What dates?

A club event on the 29th.

I agree with you it does not help you to drift because it is difficult to find the right amount of slide before the system intervenes. For real drift, off is the only way at my (low) level of driving quality.
During my trip I was mainly with DSC off BUT when wet or cold (moutain passes with snow at 2500 m high) I switched to MDM as a security.
Most of the time the system was cuting the slide I expected and my dear wife as passager found this not comfy, not natural ? So I was finally driving less aggressively with the MDM on and found that it was possible to slide more cleanly but not more widely than with DSC off.

Not help you drift so to speak, just prevents it from getting out of control.

I found that at first I just booted it and thought it would help me drift. What I found is that it harshly cut the power straight away.

Now I just gently feed in the power more and more until it starts to slip, as long as you hold the throttle relatively constant from that point it wont cut the power.

This results in big fun with long slides at sensible angles with the computer there to catch it if it all goes to pot.

I've only briefly played with DSC off in the dry, bloody hell, kicks the back out far more readily than the Monaro! Again

Thanks for the info.

MDM is a brilliant way of learning that - contrary to what feels natural - the smoother you are the wider and longer you can drift a car. Once you can persuade the car into long, sustained drifts with it on you'll be amazed what you can do with everything switched off! Most drifts end either because they're started too violently, corrected too violently - or both! I guess correcting too much - for the slide to continue - is pretty natural as most folks (non PHers probably!) who get into a slide on public roads want/have been taught to get out of it a.s.a.p. - not prelong it like us lot! Most skidpan days etc., teach you how to kill a slide, not hold it there.
