Euro MDM on M2 PE = amazeballs
Coded Euro MDM on the M2 using the one liner method since my car is a 02/17 prod. I haven't driven the car on the regular MDM, but Euro MDM is pretty solid!
Getting closer to 1200 miles and slowly driving the car harder and harder... It allowed a decent amount of slip angle accelerating out of a left hander in 2nd.. it still reigned itself in a bit by reducing power while I corrected. In 1st gear it's wild... allowed plenty of tire slip lol 0 traction intervention... Every day this car makes me smile that much more.

I coded with esys, and I also have ISTA+ to clear the codes afterwards. If you're going to the canyon run, I can help ya out! Yup, all I did was change the DSC Market to ECE documented here: C_Laenderkennung set to: ECE

Yes, I'm fully aware, it was not intentional

here is what I understand: MDM has nothing to do with throttle response per-se, MDM is a mode of the DSC, and the DSC can intervene to cut power to help recover a spin when it is beyond certain limits built into the algorithm. MDM will allow an increased wheelspin and a certain amount of sideways sliding before it will start intervening with power cuts and/or braking specific wheels. Euro MDM is simply parameterized with different limits and settings than the US MDM, allegedly it should allow for wider margin of sliding. MDM is not selectable directly: it is active in TRACTION mode and in SPORT+. |

Straight line performance is definitely helped by Euro MDM. Still not as good as DSC off, but closer to it than US MDM. Im confused by all the guys who claim they're "getting sideways" on the street and/or spinning out following Euro MDM coding. You must be mashing the throttle in first or second and locking the wheel in 90 degree turns, in which case no TC on earth will save your momentum. |

I found myself very much sideways (like 45 degree) with MDM .. on a straight line... which was very surprising. This hapenned because of a transition between different road surface during straighline hard acceleration, on road slightly wet. I went same place again another day with nanies on and TC is really flashing a lot on the same spot despite not pushing very hard.

I can tell you that with DSC off: In a 2nd gear corner, hit the apex, plant the front wheels, and roll on the throttle. Depending on how persuasive rolling into WOT you are, you can achieve a mild to extreme power slide quite easily with the M2's short wheel base. I've found in the above scenario with US MDM, I can get a slight rear wiggle followed abruptly by computer correction. Euro MDM will allow maybe 20% more slip IMO, before crashing the party. Either Euro MDM is useless if you're used to driving with DSC off, or I had a coding error and am actually still under the iron fist of US MDM! |

I can't wait to drive the F87 on the track with DSC Off, it seems really well balanced.

I just drove it today with DSC off abit hard on public streets ( no intentional sliding was done ), car felt really balanced and in situations where I thought it would cut power with full nannies on it didnt... no hint of oversteer either Just like the GT86 I had before... the car really seems to drive better even on the street with 0 nannies on. I'm 6MT so rev matching / heel toe myself was soo satisfying. I'm glad I still revmatch / heel toe when I'm in comfort throttle to not be too rusty.

DSC off, MDM is for rookies. This car is so neutral and easy to drive.
