13 Honda Odyssey brush ecu can improve the power of turbocharged engine. 13 Honda Odyssey brush ecu can improve the working efficiency of the car, increase the power of the engine, speed up quickly, and stabilize the speed. Automobile ecu refers to an electronic controller unit composed of microprocessor, memory, input/output interface, analog-to-digital converter, shaping, driving and other large-scale integrated circuits, also known as automobile running computer. Working principle of ecu: By reprogramming the engine computer instead of making the engine work in the limit state, the parameters such as fuel supply and ignition curve are fine-tuned on the basis of the original factory data, and many values are optimized, so as to achieve the purpose of increasing output horsepower, improving torque, adjusting speed limit or reducing fuel consumption.
