What is ECU remapping?
ECU remapping adjusts the software calibration in an engine control unit. The maps and their relationships determine how the engine is controlled across different operating conditions.
Why the details matter
Calibration involves interacting parameters rather than a single setting. Vehicle configuration, hardware, software version and the intended application must be considered together. Measurements and data logs help assess a particular project.
Remapping and external tuning devices
A remap changes the ECU software itself. An external tuning device is additional hardware connected to the vehicle. The correct approach depends on the project and the equipment involved.
