ECU Remapping

What is an ECU Remap?

An ECU Remap is a re-flash of the engine management system which installs new software to change the operating parameters of the engine. An ECU Remap will alter parameters including throttle position, Fuel duration, boost pressures, torque limiters, boost limiters, fuel pressure limiters, lambda correction and many more. Engine Tuning and ECU Remapping has become a huge industry over the last 15 years as modern engines have become fully electronic and therefore able to receive engine tuning via ECU Remapping.

What are the benefits of an ECU Remap

An ECU Remap will provide a much improved drive with sharper throttle response, greater in gear flexibility, more power throughout the entire RPM range and on diesels will also improve your fuel economy.
