What Is ECU Remapping?

ECU remapping—also known as chip tuning or car remapping—is the process of reprogramming your vehicle’s Engine Control Unit (ECU) to improve performance, efficiency, and responsiveness.

With professional ECU remapping, we can:

Increase power and torque

Improve fuel economy

Enhance throttle response

Optimise settings for your driving style

How We Perform ECU Remapping

Using advanced diagnostic tools and tuning software, we connect directly to your ECU via the OBD port—or remove it for bench tuning when required.

We fine-tune parameters such as:

Fuel injection timing

Turbo boost pressure

Ignition timing

Throttle response mapping

Every ECU remapping session is custom-written for your car, then tested on a dyno to ensure maximum gains with complete safety.
