I stumbled across a write up of DTC for our MK60 module.

"DTC achieves maximum possible traction essentially by expanded ASC and DSC control thresholds. Compared to the ASC/DSC function, DTC mode allows a little more "drift" at low speeds and transverse acceleration (increased rear wheel spin is permissible up to a speed of approx. 45 mph). This allows the engine power output to remain without an extreme reduction of power, improving propulsion.
On approaching higher speeds and transverse acceleration (measured by the yaw rate sensor), the DTC function acts more and more like the "normal" ASC and DSC function and the slip thresholds are reduced back to a conservative mode for stability reasons."
