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.
