MOTRONIC M 3.8.X (MPI) training board-simulator is installed in a mobile aluminum frame. This training board-simulator is specially designed to help technical students understand multipoint petrol injection (MPI) system MOTRONIC M 3.8.X. The educational training board is based on Audi/VW OEM components. The integrated engine control system shows different operation modes of the fuel injection/ignition system. The training board-simulator is a great educational tool that allows students to learn the structure of engine control system, study its components and operation modes, perform various measurements, tests and other diagnostic procedures.
