Humans have brains, computers have CPUs, and automobiles have ECUs.
If you compare a car to a person, then the four wheels are human limbs, the body and chassis are human bones, various circuits and lines are human feedback nerves, and ECU controls various human thoughts. And behavioral brain. In many cases, whether a person is smart or not depends on whether his brain is good or not. And to see how a car's performance is, most people look at its engine performance. In fact, the most important part that determines the performance of the entire vehicle is its ECU.
Internationally, ECU has two translation methods: Electronicl
Control Unit (Electronic Control Unit) or Engine Control Unit (Engine Control Unit), usually called "engine computer" or "travel computer" in China.
ECU upgrade:
ECU upgrade comes from foreign countries. In China, it is also called ECU brushing, car computer upgrade, computer brushing, ECU modification, etc. In fact, ECU upgrade comes from the formal translation method, which is ECU adjustment. Its working principle: by rewriting the program in the engine computer, the fuel supply and ignition curve and other parameters are fine-tuned on the basis of the original factory data, and a number of values are optimized to increase the output horsepower, increase the torque, and adjust the speed limit. Or reduce fuel consumption and other purposes.
What is the effect of ECU upgrade?
A The performance of naturally aspirated models is improved by 5%-15%.
The performance of the B turbo model is increased by 15%-36%.
C Maintain original driving habits and reduce fuel consumption by 5%-25%.
D Release the speed limit and the maximum engine speed setting.
E Other functions: Idle speed adjustment, extended shift timing, fuel injection time setting, intake air temperature and water temperature fuel supply compensation, fuel injection nozzle opening and closing rate, instantaneous foot throttle fuel supply increase setting, engine overturn Oil cut-off device, intake air flow, knock feedback, overpressure, etc.
