BMW X5: DTC Dynamic Traction Control
Principle
Dynamic Traction Control (DTC) is a version of the Dynamic Stability Control (DSC) where drive power is optimized.
The system ensures maximum drive power on unusual road conditions, for instance unplowed snow covered roads, or loose road surfaces, but with somewhat limited driving stability.
General information
When DTC is activated, the vehicle has maximum traction. Driving stability is limited during acceleration and when driving in curves.
You may find it useful to briefly activate DTC in the following situations:
- When driving in slush or on uncleared, snowcovered roads.
- When driving off from deep snow or loose ground.
- When driving with tire chains.

Engine Adaptation Values
Engine adaptation values can be broken down into two categories:
Additive Mixture Adaptation - additive adaptation refers to "long term
fuel trim". These adaptation are
made by the ECM (DME) at idle during "closed loop" fuel control. These
values are measured in
milliseconds and are expresse
