ECU Unlock
An ECU unlock is the process of removing the manufacturer's read/write protection on a vehicle's engine control unit, giving tuners access to the internal calibration data using flash tools. This restores the ability to read the original calibration, modify maps and parameters, and write custom software back to the unit, forming the foundation that other services, like map switching or custom calibration, are built on top of.
