What Is ECU Tuning?

Unlock Your Engine's Potential

Every modern vehicle is controlled by an ECU — an Engine Control Unit — that governs fuelling, ignition timing, boost pressure and more. Manufacturers deliberately program these settings conservatively to meet global fuel standards, emissions targets and to protect warranty claims.

A Bray AutoTech ECU remap replaces these factory parameters with a calibration tailored to your vehicle, releasing the performance the engine was built for. The process is entirely software-based, done via the OBD port or directly on the ECU, and leaves no visible trace.
