I think that DRUCKMODELL settings for MAN_UMF_GTS could be a compensation for the larger diameter brakes that came on the M3 GTS. Can anyone confirm/deny this?

More interestingly, does anyone know what PRE_MSR_E82M setting controls?

NCSDummy says this is
Code:
E82 (1 SERIES M COUPÉ) PRE ENGINE DRAG-TORQUE CONTROL

Thanks for sharing I actually think the MSR is for DCT launch control, after looking at it a little closer and comparing to M3/Z4. Now I feel like I have to get another 1M and DCT swap it, all the options appear to be present for it.

I was able to get the coding done today. Here is what I read from the car:
Code:
RPA
	nicht_aktiv
MSA
	nicht_aktiv
MDYNAMIC_MODE_USA
	aktiv
LAT_EBD
	aktiv
US_VEHICLE
	nicht_aktiv
POHO
	nicht_aktiv
DDS_PLUS
	nicht_aktiv
ABSCHALTBARKEIT_DSC
	aktiv
DRUCKMODELL_HA
	wert_00
DRUCKMODELL_VA
	wert_00
GETRIEBE_E82M
	wert_00
PRE_MSR_E82M
	nicht_aktiv
UEBERSTEUERN_MUE_0
	wert_01
UEBERSTEUERN_MUE_1_2_M
	wert_01
Here is what I modified it to:
Code:
RPA
	nicht_aktiv
MSA
	nicht_aktiv
MDYNAMIC_MODE_USA
	nicht_aktiv
LAT_EBD
	aktiv
US_VEHICLE
	nicht_aktiv
POHO
	nicht_aktiv
DDS_PLUS
	nicht_aktiv
ABSCHALTBARKEIT_DSC
	aktiv
DRUCKMODELL_HA
	wert_00
DRUCKMODELL_VA
	wert_00
GETRIEBE_E82M
	wert_00
PRE_MSR_E82M
	nicht_aktiv
UEBERSTEUERN_MUE_0
	wert_00
UEBERSTEUERN_MUE_1_2_M
	wert_00
Unfortunately, it is another rainy day, so I will have to report back later with more details on noticeable driving dynamics changes.

After testing on semi-dry roads today, I can say that the rear end definitely comes farther around and the interference that does occur definitely seems less like “fun time is over” and more like “let us keep you on the road.”

I have previously installed a drexler differential in my car, so YMMV, but it feels much better

I was digging back into MK60 coding, and did a side-by-side comparisons in NCSDummy of 1M vs M3 data values, option codes, etc. Stock US 1M values are the same as US E92 M3, for both 'OVERSTEER FRICTION COEFFICIENT' settings; which could explain why it's a little too intrusive.

Euro 1M setting for MUE_0 is the same as Euro E92 M3: E6
Euro 1M setting for MUE_1_2 is a unique value, not used for any M3 variant: E0
- for this setting NCSDummy shows calculated values for M3 MK60
- the calculated value for Euro 1M is 2 m/s^2, whereas Euro E92 M3 is 1.703 m/s^2
- the calculated value for US 1M/E92 M3 is 2.203 m/s^2

I do not fully understand the practical implications of what you've found in the 1M vs M3 NCSDummy comparison?

We know that 1M is a parts bin car, mixing E82 135i with E92 M3. We also know that BMW has held back performance features from US market cars. I was just trying to show exactly what those differences are.

As an engineer, I work from the assumption that these parts are mostly the same, with some different firmware versions to properly interpret the settings. For example, M3 MK60 shows 8 possible values (wert_00-wert_07) for the oversteer friction coefficients, whereas 1M MK60 shows 2 possible values (wert_00-wert_01). Here is a breakdown:

US MUE_1_2
E93 M3: 3.5 m/s^2
E90 M3: 2.797 m/s^2
E92 M3: 2.203 m/s^2
E82 1M: 2.203 m/s^2

Non-US MUE_1_2
E93 M3: 2.594 m/s^2
E82 1M: 2.000 m/s^2
E92 M3: 1.703 m/s^2
E92 M3 GTS: 1.703 m/s^2

Now that I'm looking at it again, I don't see a listing for Euro E90 with S65B40, only with S65B44 (which should be GTS engine); so it might be that Euro 1M and Euro E90 M3 have same MDM settings.

I don't know the exact calculation, but, thinking about safety, I would assume that BMW would reduce customer's ability to drift in E93 where there is no roof to keep unbelted passengers in the car. My extrapolation being that the larger the MUE_1_2 value is, the sooner the ECU will intervene for you.

I will make another assumption now that you've got my noodle going... I think that MDYNAMIC_MODE_USA being active removes the steering angle sensor from the calculations; which is why it is such a quick end of sliding. I bet if you leave the oversteer friction coefficients alone and just switch this off, the MDM will be more graceful on US cars.
