As one of the most inherited models in the history of car design, the Mercedes-Benz G-Class has maintained a boxy shape since its birth, and you can spray its designers to inaction, but after all, this is a classic that everyone recognizes, how can you make changes casually?However, this also brings a problem: the old model does not look old, and the ** model does not look new. The eternal square box design is also the most impressive G-class brand for the Chinese people, and fans have given it a friendly name - "Big G", and the protagonist of today's operation is this 20T Mercedes G350.
The Mercedes-Benz G350 is equipped with the M264 engine developed by Mercedes-Benz, and the G350 is a high-power version. Twin Scroll Single Turbo Technology, Variable Valve Lift Technology, Demand-Controlled Multi-Point Injection System, Nanoslide Cylinder Wall Coating Technology;Engineers also increased the strength of the crankcase with new plastic engine mounts to improve noise, vibration and harshness from the engine compartment. With the support of many advanced technologies, in terms of power parameters: 5800-6100rpm can burst out of 190kW of maximum power, and at the same time can continue to output 370N·m of peak torque at 1800-4000rpm, and the matching transmission system is a 9-speed automatic transmission. For a medium and large SUV, 20t power parameters, can not avoid the small horse-drawn car, and the car in the actual driving of the subject of this topic, the car in the driving of low speed and rapid acceleration power lag phenomenon is very significant, coupled with the existence of low-gear shift frustration, affecting the overall driving control of the comfort of the ride. In order to expand the best power and handling of this car in China within the safety range, one-to-one customized brush ECU is a good option.
First of all, the road test is carried out to collect the log data of the engine, and then the flash in the engine computer is read out through the special equipment, and the read data, the log data of the actual vehicle test, the oil of the vehicle configuration, the reasonable needs of the riders and other objective information are transmitted to foreign program providers to ensure the pertinence and stability of the program
ECU is the abbreviation of electronic control unit, that is, what we call the driving computer, if the car is compared to a person, the engine is his heart, ECU is like "his" brain, the heart "runs" well, it depends on how the brain is. Cars leave the factory with the car to be sold all over the world, adapted to a variety of different environments and oil quality, so the program in the original ECU is the best compromise that meets many conditions, that is, at least 30%-40% of the energy is sequestered (especially European cars that are known for their safety). Unleashing this energy allows it to perform beyond the ordinary. It is also to lay a good foundation for further modifications.
After three hours of waiting, the customized optimization program has been implanted into the engine's control system, and after passing the special equipment detection, the next step is to collect log data for the road test to determine the rationality of each vehicle optimization
The actual results of the road test are summarized as follows:
1. At the moment of starting, you can feel that the car is lighter, the phenomenon of low speed and low torque and rapid acceleration power lag is improved, and the acceleration feeling is continuous and more linear on call
Two: the shift logic is clearer and smarter, the shift is more positive and smooth, although the low gear frustration has not been able to **, but it has been improved better than before, and the overall driving control feeling of the upgrade of power and handling is more linear;
Three: The sound is more deep and thick, and the Mercedes-Benz G350 brush ECU upgrade is very cost-effective and safe.
As the saying goes, "motivation is like money in your pocket, you can do without it, but you can't do without". Brushing ECU is currently the most direct, effective, safest and most economical modification method in terms of automobile power modification. Orthodox ECU upgrades are built within the limits of what the car's hardware can fully afford. The optimization and upgrade of the ECU is to fully give full play to the more accurate calculation of the car, that is, to accelerate the speed of ECU calculation, after the ECU upgrade, it will only improve the combustion efficiency of the engine, and will not cause any harm to the engine, and will also increase the driving pleasure and make the driving more targeted.
