The disadvantage is that the pressure on the frame, tires and brakes will increase after the ECU is brushed.

Electronic control unit, also known as "trip computer" and "vehicle computer". In terms of use, it is a special microcomputer controller for automobiles, also called a special single chip microcomputer for automobiles. It consists of microprocessor (CPU), memory (ROM, RAM), input/output interface (I/O), analog-to-digital converter (A/D) and large-scale integrated circuits such as shaping and driving, just like an ordinary single chip microcomputer.

In general, the voltage working range of ECU is 6.5- 16V (internal key points have voltage regulators), the working current is 0.0 15-0. 1A, and the working temperature is -40℃~80℃. It can withstand the vibration below 1000Hz, so the probability of ECU damage is very small. CPU is the core part of ECU, which has the functions of calculation and control. When the engine is running, the signals of various sensors are collected and calculated, and the calculation results are converted into control signals to control the work of the controlled object.
function
General ECU has the function of fault self-diagnosis and protection. When the system fails, it can also automatically record the fault code in RAM, and take protective measures to read the replacement program from the above-mentioned inherent program to maintain the engine running. At the same time, these fault information will be displayed on the dashboard and will be immortal, so that the owner can find the problem in time and drive the car to the repair shop.
