Automobile engine ECU demonstrating board

The utility model provides an automobile engine ECU demonstrating board, including a plurality of signal generating module, the simulation produces each item working parameter of automobile engine, a plurality of sensor is through detecting each item working parameter generates corresponding electrical parameter, a plurality of signal selection switch, respectively with the sensor with signal generating module connects switch between sensor and the signal generating module, the controller, with signal selection switch and ECU connect, are used for transmitting each item the electrical parameter extremely ECU, and receive the control signal that EUC sends is used for adjusting automobile engine each item working parameter extremely signal generating module, and display module. Through the analog signal input of true executor component with each item working parameter of automobile engine to send control signal control engine's rotational speed, intake air temperature, temperature, intake pressure etc. Through ECU, adopt the matching method of analog signal and true ECU data, can detach the engine that area is big.
