The latest generation EA888.4 2.0 TSI engines in 2025+ VW Group cars like the Golf Mk8.5 GTI and Audi A3 8Y.5—can’t yet be tuned through traditional ECU remapping. That’s where the RacingLine PCM (Power Control Module) comes in. Developed specifically for these engines, the PCM is a plug-and-play tuning box solution that delivers immediate, safe, and trace-free performance gains.
Expect up to +50 HP and +80 lb-ft of torque for lower-output Garrett turbo models, with smooth, progressive power throughout the rev range not just at the peak.
Why Choose RacingLine PCM?
- Exclusive Development for EA888.4 Engines – Calibrated in-house over 12 months to safely optimize factory ECU signals for real-world power gains.
- Free ECU Tune Upgrade – When full ECU calibrations become available, PCM owners get a free upgrade (when purchased from an authorized RacingLine Software dealer).
- Easy Installation – Just three plug-in connections to the wiring loom with pre-made brackets for perfect fitment. No cutting, splicing, or permanent modifications.
- Completely Reversible – Remove anytime without leaving physical or digital traces.
- Premium Build Quality – Housed in a billet aluminum case with cooling fins, paired with a carbon fiber mounting bracket for a factory-plus look in the engine bay.
- Dyno-Proven Gains – Power delivery focused on maximizing the “area under the curve” for faster acceleration, sharper throttle response, and better mid-range punch.
How PCM Works
The standalone PCM unit communicates directly with the factory ECU via a dedicated wiring harness. By optimizing sensor signals in real time, it safely raises boost pressure, adjusts fueling, and enhances ignition timing—all while keeping factory safety parameters intact.
