EA1111.4t power scheme 4S shop can brush it. 4s stores can brush programs, ECU electronic control units, also known as driving computers, car computers and so on. In terms of use, it is a special microcomputer controller for automobiles. Like ordinary computers, it consists of microprocessor, memory, input/output interface, analog-to-digital converter and large-scale integrated circuits such as shaping and driving. In a simple sentence, "ECU is the brain of a car."

Engine introduction

Different power versions of engines are produced by different ECU, so the difference between them must be attributed to ECU, but there are some other factors besides ECU. For example, the engines developed by some car companies are slightly different in intake mechanism, connecting rod, piston and even intake manifold except ECU control program, and only in this way can they withstand higher compression ratio.

Brush ECU, also known as ECU upgrade, automobile computer upgrade, ECU modification, etc. In fact, the official translation is ECU adjustment; The working principle of brush ECU: By rewriting the program, the fuel supply and ignition are fine-tuned based on the original factory data, and the parameters are optimized to achieve the purpose of increasing output horsepower, improving torque or reducing fuel consumption; Increasing horsepower and torque correspondingly increases fuel consumption, while decreasing horsepower and torque correspondingly reduces fuel consumption.
