Automobile electronic control unit optimization system

The invention discloses an automobile electronic control unit optimization system. The automobile electronic control unit optimization system comprises a main input and output circuit part, a power source part and a signal amplification part which are all sequentially connected. The signal amplification part comprises a regulating plate, a main control panel, a first resistor, a second resistor, a third resistor, a fourth resistor, a fifth resistor, a sixth resistor, a first capacitor, a second capacitor and a diode. An accelerator position sensing line of the main control panel is connected with a signal output interface (Signal-out). A gas inlet temperature sensing line of the main control panel is connected with the second resistor and the sixth resistor. The second resistor is connected with the sixth resistor in series. An oxygen sensor line of the main control panel is connected with the first resistor and the third resistor. The third resistor is connected with the fourth resistor and the fifth resistor. The first resistor is connected with a signal input interface (Signal-in). A data line of the main control panel is connected with the fourth resistor and the regulating plate. With the automobile electronic control unit optimization system, oil consumption can be lowered; power of automobiles can be improved; performance is reliable; and tail gas emission is optimized. Moreover, the automobile electronic control unit optimization system is safe and environment-friendly.
