GMProg is an Android mobile application that enables programming of control blocks (ECU) of General Motors' (BUICK, CADILLAC, CHEVROLET, OPEL, etc.) cars using OBD II ELM327 Bluetooth adapter. This is the first app of its kind that performs this function. The app requires Bluetooth connectivity to function. It allows users to obtain an ID, register or sign in through a browser on the website, choose an automobile, model, and block, and enter the ID obtained previously.

The app supports specific models of OPEL, GMC, CHEVROLET, BUICK, and other compatible vehicles. The app allows activation of dashboard computer tabs such as coolant temperature, battery voltage, and gearbox oil temperature. However, users must note that working with IPC is only possible with original devices such as OBDLink MX, ELS27, Vgate vLinker.

GMProg is a useful application for car owners who own the supported models and want to take control of their car's ECU. The app is available for free download on the Google Play Store.
