Engine switching occurs when a vehicle's onboard computer (often referred to as the electronic control unit or ECU) is modified with new software to influence its behavior. Ex-factory, most cars don't offer the maximum possible engine performance - even sports cars. The ECU typically limits engine performance to improve reliability, emissions, and fuel economy. Your car's engine may also be slightly restricted to ensure it strikes the right balance between fuel economy and full performance in less than ideal conditions, e.g. in very hot weather (when the engine normally produces less power). Diverting is usually done ...
