Racingline Power Control Module (PCM) – Audi RS3 8Y (2021+)
The latest 8Y generation Audi RS3 has been notoriously difficult to tune through traditional ECU remapping. Racingline’s Power Control Module (PCM) is a clever workaround, developed specifically for the RS3 8Y with the 2.5 TFSI Evo engine, giving you a meaningful jump in performance without permanently altering the factory ECU.
This particular listing covers the OPF/GPF version (DNWC engine code). If your car does not have a particulate filter (DXHA engine code), you will need the alternative part number VWR030001-RS38Y. Please check the Vehicle Fitment tab or use the site’s vehicle lookup tool to confirm the correct version for your car.
What the PCM does
PCM stands for Power Control Module. It is a standalone PCB (printed circuit board) that communicates with the factory ECU, safely increasing the power and torque your engine produces. Racingline’s in-house calibration team spent over 12 months developing the unit, and the result is smooth, progressive gains throughout the rev range rather than a sudden, peaky surge.
- Power increase to around 450HP and 600Nm
- Smooth, linear delivery across the full rev range
- Easily installed, and easily removed at any time with no trace left behind
- Works alongside the factory ECU, not by overwriting it
Why this matters for the RS3 8Y
At launch, the 8Y RS3 simply could not be remapped in the usual way due to the security on its ECU. The PCM gives owners a way to enjoy more performance now, rather than waiting indefinitely for a traditional tune. It is a sensible interim solution that respects the engine’s limits while clearly waking the car up.
Free upgrade to OEM+ ECU tuning
Racingline understands that many owners will eventually want a full ECU calibration once it becomes available. To that end, any PCM customer is offered a free upgrade to Racingline’s OEM+ ECU calibration when it is released, provided the PCM was purchased from an authorised OEM+ dealer. As an authorised Racingline retailer, your purchase here qualifies.
