Programming the DSC MK60 for LSD

Why don't I see any vids, Derek?

^this!

Welcome to one button DSC. Isn't it great?

Because I dont have a guy to hold the camera nor a parking lot that is safe to not get caught by cops.

I'm reading to gain a better understanding.

Modified ADB function (2-wheel drive vehicles equipped with MK60)
The ADB is an automatic differential lock that improves traction. The slipping wheel is
braked by pressure built up in the hydraulic unit. The drive torque can be transferred to the
wheel with the greater traction, which can transmit drive power to the road. This function
takes the place of a limited slip differential.
The MK60 DSC III system incorporates two methods of ADB based on the DSC switch
input to the control unit. With the system “on” the ADB works with engine intervention at
a threshold of below 40kph(24 mph).
Tapping the DSC switch (<2.5 s) increases the slip threshold of the ADB up to
approximately 70 kph (42 mph) for the purpose of increasing traction.
This feature is also helpful for example when rocking a vehicle out of mud or snow.

Cops? As in Po-lice? Nah... just get it done before they get there. If they come up on you afterwards, just tell them that it is time for new tires, and it is hard to keep them from spinning... You are sorry, but all you want to do is get home...

Honestly I'm just lazy to do Shenanigans :P

I'm also curious on the M track mode enabled on a non-M. It appears someone made it work on Terra's thread about M-track Mode.

OK......now I am interested.

Comparing the NON-M DSC values to the STD M3 and ZCP M3 is an order.

Terra already did the STD to ZCP.

If so did you notice a difference in the intervention, even without M-track mode enabled? I ask, because I was comparing the default coding data between a ZCP and non-ZCP M3, and there are quite a few differences - seems to go beyond the differences that are there due to the brakes, steering rack, and M-track mode. In fact, it seems like all of the settings are taken directly from the CSL. If anyone is interested, the settings are in the code boxes below. It's all German (and some cryptic abbreviations too), but maybe you guys can make some sense of what type of values they're changing. First box is the differences only. Second box is default M3. Third box is ZCP

FWIW, When you perform the retrofit coding for the ZCP/CSL brakes on a standard M3, the only thing that changes is "DRUCKMODELL_HINTERACHSE" which translates to "pressure model rear axle", which makes sense considering the larger rear pistons. "LENKWINKELKENNLINIE_2" has to do with the steering angle sensor calibration, which is due to the quicker steering rack.

I'm not sure. But if it can be done for free with some coding in the garage then I'm all for it.
