Using coding to fight against DSC intervention during DCT Launch

Hi Everyone,
Meanwhile we wait on MHD or any other solution to get DSC intervention completely off during Launch Control and even Launch Control RPM adjustment. I've been trying to find alternative temporary solution by just coding the DSC module or maybe any other module that could help us fighting against the boggy Launch Control the non-M DCT cars have.

After digging into the modules via NCS Expert and doing some research at some other forums, I found an interesting thread for M5/M6 users that are able to change some wert values at the DSC module in order to get less intervention during launch.

These are the parameters:

With NCSExpert change in DSC:

UEBERSTEUERN_MUE_0_2
wert_01 to
wert_00

UEBERSTEUERN_MUE_1_2
wert_02 to
wert_00

UNTERSTEUERSCHWELLE_2
wert_00 to
wert_01

MDYNAMIC_MODE_USA
aktiv to
nicht_aktiv

A few other options changed for me however I am pretty sure they are for non 08+ w/o TPMS. I also wonder if only "MDYNAMIC_MODE_USA" needs to be changed or if the other values are required for thresholds.

I have been driving on this and feel less bogging of the throttle. Look forward to hearing what other people think.

Keep in mind this is a E60 only change. If you want this for your M6 or M3 perhaps start with only turning off "MDYNAMIC_MODE_USA" first or find a euro VO to compare with.​


When trying to check this in my own DSC module on my E82 I can see some similar values except for the MDYNAMIC_MODE_USA one... Maybe we can adjust something else or change the wert values in order to get a different setup for the DSC intervention?

I'd have to play with my different DSC boxes to help you understand what each of these are, but the MDYNAMIC_MODE_USA isn't doing anything for you. If you have MDM then that would have a pretty significant effect. The USA version of MDM is much more restricted. The Euro MDM is more open and allows more wheel spin, and turning USA off gives you the Euro settings. But that's only while MDM mode is enabled, and for an M car, the launch control is enabled with TC OFF not with MDM enabled, so it wouldn't ever have any impact for any car's launch control.

I'm curious what the other values are really doing...

UEBERSTEUERN_MUE_0_2
wert_01 to
wert_00

UEBERSTEUERN_MUE_1_2
wert_02 to
wert_00

UNTERSTEUERSCHWELLE_2
wert_00 to
wert_01

MDYNAMIC_MODE_USA
aktiv to
nicht_aktiv
