Professional In-House ECU & TCU Remapping
At RPM Sussex, we offer expert ECU remapping at our fully equipped workshop, delivering precision tuning in a safe and controlled environment. Our remapping service is designed to enhance power, improve fuel efficiency, and refine your vehicle’s overall performance.
We use industry-leading tuning tools including Autotuner and Alientech KESS3 to ensure the highest standards of quality, compatibility, and safety. These advanced programming tools allow us to safely read and write ECU data across a wide range of modern vehicles with precision and reliability. We also offer both ECU and TCU tuning for BMW platforms and VW Group vehicles, allowing us to optimise not only engine performance but also gearbox behaviour for smoother, faster and more responsive driving. All remaps are performed in-house by experienced professionals with a deep understanding of vehicle dynamics.
