What is ECU Remapping?
ECU remapping, also known as chip tuning, is the process of reprogramming your car’s Engine Control Unit (ECU). The ECU is responsible for controlling key engine parameters such as fuel injection, ignition timing, turbo boost pressure, and throttle response.
Manufacturers often limit the power of a car to meet emissions standards and various global regulations. With a custom ECU remap, we adjust these settings to unlock your car’s full potential safely and reliably.
