Dinan PCU - BMW B58 Gen 3 Engine B58 GEN3 TU2 - Limited Warranty - D440-0201

The Dinan PCU Power Control Unit for BMW B58 Gen 3 TU2 engine is the next evolution of Dinan inline tuning technology, developed from more than a decade of experience in performance calibration modules. This advanced plug-and-play tuning solution installs between critical engine sensors and the ECU, modifying signals to safely deliver increased horsepower, torque, and overall performance beyond factory programming while maintaining OEM safety systems.

Unlike older inline modules, the Dinan PCU integrates additional connections including OBD-II communication, allowing the system to go far beyond simple boost control. With built-in Bluetooth connectivity and a dedicated mobile app, the PCU provides live vehicle monitoring, customizable gauges, fault code reading, and performance data logging, giving you complete control and insight into your vehicle at all times.

The system includes multiple pre-configured power levels plus stock mode, allowing you to choose the performance output that best matches your driving style and fuel quality. Advanced features such as boost-by-gear adjustment help maintain traction in lower gears, while real-time monitoring ensures your engine always runs safely at peak performance.

Engineered, calibrated, and manufactured in the USA, the Dinan PCU is designed to preserve factory safeguards and emissions controls while adding its own protection strategies for reliable daily use. With available Dinan factory-matching warranty coverage, this is one of the safest and most complete tuning solutions available for the B58 Gen 3 platform.
