Racingline Power Control Module (PCM) – Audi RS3 8V OPF
Racingline Power Control Module (PCM) is a plug-in tuning module developed specifically for the 2.5 TFSI engine in the Audi RS3 8V.2 with OPF. It provides a noticeable increase in power and torque while retaining the vehicle’s everyday usability and engine character.
How the PCM module works
PCM is a compact electronic module that connects to the existing engine sensors. It reads current data and adjusts certain signals so that the engine control unit (ECU) can optimise fuel delivery and boost pressure for increased performance. Unlike conventional remapping, the PCM module can be removed completely; once disconnected, the vehicle returns to its standard state.
For the 2.5 TFSI DWNC engine with OPF fitted in the Audi RS3 8V.2, the following figures are stated:
- Power: from 400 hp to 452 hp
- Torque: from 500 Nm to 601 Nm
Effect on driving characteristics
The PCM module was developed through extensive dyno testing and real-world driving tests for this engine. The result is improved throttle response, stronger pull through the mid-range and a more convincing top end. Torque and power are delivered progressively, so the vehicle feels like a sharper version of the standard model.
Installation
Installation is suitable for users with basic mechanical knowledge. The module is mounted above the battery using the supplied carbon mount and fixings, while the wiring harness connects to the existing sensors on top of the engine. No cutting or soldering is required.
Important
The power increase figures are based on dyno measurements, while actual results may vary slightly depending on engine condition, additional equipment, fuel quality, other modifications and the measurement method used.
The product was developed exclusively for the 2.5 TFSI DWNC engine in the Audi RS3 8V.2 with OPF (Otto Particulate Filter). Check the engine and vehicle specification match before installation.
Suitable for: Audi RS3 III (8V).
