Description
Haldex ECU Upgrade Gen IV – Competition Mode for Audi TTRS
This ECU upgrade is engineered for drivers who demand maximum traction and instant response from their Gen IV Haldex system. The Competition‑mode delivers the same aggressive tuning as the Race version — but with an added advantage: active torque distribution to the rear wheels even under braking. Competition mode provides a far more aggressive clutch strategy compared to OEM, resulting in:
- More stable power delivery at high speeds
- Reduced delay in clutch regulation
- Predictable handling during hard driving and track use
- Faster rear‑axle engagement during acceleration
- Active torque distribution to the rear wheels even under braking, enabling left‑foot braking without clutch disengagement.
The unit has been tested under extreme heat, load and repeated high‑stress conditions — making it the ideal choice for Audi TTRS owners looking to push their car to the next performance level.
