Programming the DSC MK60 for LSD

[wertyu78]

Interestingly enough, I found this option on the MK60 DSC unit awhile back. Now that I have a LSD, I will enable it.


"LOGIK_HA_SPERRE"
Logic Limited-Slip Differential


Has anyone changed this to Aktiv, and know of any benefits this may yield? I am going to change mine over to Aktiv now... Will report back!

Update:

I've set "LOGIK_HA_SPERRE" to Aktiv. Going for a drive soon

SPERRDIFFERENZREGELUNG (Differential Locking Control) is set to Aktiv normally, but standard E46 M3 is set to nicht_aktiv. I've set mine to nicht_aktiv.

TRAKTIONDIFFERENZREGELUNG (Differential Traction Control) is set to Aktiv normally, standard E46 M3 is set to nicht_aktiv and E46 M3 ZCP is set to Aktiv. I've set mine to nicht_aktiv.


Update 2:

I've not yet driven the car, but I've started it to test the disabling and enabling of DSC. Now I only have one "mode" of DSC. Holding it for 5 seconds doesn't illuminate the BRAKE light yellow anymore.

Update 3:

Driving the car is a blast with the LSD. The DSC system does work differently with the M3 settings, but I'm not able to find a way to describe it. It's convenient to have a simple on/off 1 button press to enable or disable the DSC.

There are a lot of other features that we may be able to edit such as.... Under-steer and Over-steer friction coefficients, under-steer and over-steer algorithms, etc.

I'd love to have a lesser traction control setup but keep the well engineered stability control as well as the ABS.

I love playing around with coding, but I will not mess with the stability management systems... I'd hate to have an unfortunate situation due to a crash because of improperly set traction/stability management...

BUT, good luck and have fun! Report with everything you learn...

Seeing that the three earlier mentioned options are OE configured, I'd feel 100% comfortable to changing those with the LSD.

I agree with you on the others though. I'd hate for something unfortunate to happen.

I wonder what this will do.

I thought the LSD was purely mechanical when you turn off the DSC?

Mine is purely mechanical clutch type LSD. I'm wondering if that when DSC is on it has something to do with measuring each wheels speed and the cars yaw sensors to determine the cars slip rate and angle to determine when to cut throttle and/or engage a wheels brake.

oh and..

Very nice.

Yes I am curious too.
