Method of detecting engine tuning of vehicle

A method of detecting engine tuning of a vehicle is disclosed. The method of detecting illegal tuning of the vehicle may include obtaining and storing, by a controller, at least one of learning information including a variable value and a control value and engine state information at a time of controlling the vehicle while the vehicle is driven, as a learning value; comparing, by the controller, alearning value, which is newly obtained over time, with a prestored previous learning value; determining, by the controller, that a tuning chip for changing component performance in the vehicle is mounted when the learning value is changed and there remains a difference between the obtained learning value and the prestored previous learning value at a predetermined level or higher for a predetermined period of time; and creating and storing, by the controller, a tuning detection code when it is determined that the tuning chip is mounted. 本申请公开了种检测车辆的发动机改装的方法。种用于检测车辆的非法改装的方法可以包括：在车辆行驶时，通过控制器而获取并存储控制车辆时的包括可变值和控制值的学习信息与
