Since 2016, the Porsche brand has introduced a 4-cylinder turbo architecture into its mid-engine convertible Boxster and hardtop two-door Cayman series, and even the names of the two models are also prefixed with 718, the most important thing is to pay tribute to the brand's 1950 1960s well-known mid-engine racing car 718, as Porsche's sports car twins, Boxster and Cayman are the representatives of entry-level sports cars. The mid-rear-wheel drive layout, which is rare in its class, makes it even more fun to drive, and the protagonist of today's operation is the Porsche 718 Cayman.
The Porsche 718 Cayman is equipped with just a 20t horizontally opposed four-cylinder engine, this all-new 2The 0T turbocharged engine adopts the VTG (Variable Geometry Turbo) turbocharging technology derived from the racetrack, which significantly improves the engine efficiency, and its principle is that a wastegate valve is added to the supercharger, which can adjust the turbine guide vanes to control the supercharger at all times to achieve the best efficiency. When you select the "Sport" and "Sport Plus" driving modes, the bypass valve is closed, the ignition is delayed, and the throttle valve is pre-opened, which allows the car to maintain the same torque, increasing the air volume of the engine, increasing the boost pressure and providing higher instantaneous torque. The engine has a maximum power of 250 hp (6,500 rpm) and a peak torque of 310 Nm (1,850-5,000 rpm), and is mated to a seven-speed PDK dual-clutch gearbox.
Although there is only 14 tons of model configuration this set of power parameters can be said to be enough, for a sports car for sufficient power reserve is not available, in addition to the car at low speed and rapid acceleration power lag, low gear shift frustration phenomenon is still very significant impact on the fun of driving and ride comfort, in order to expand the best power and control of this car in the country within the safety range, one-to-one customized brush ECU is a good option.
First of all, the whole vehicle is systematically tested to ensure that the vehicle is optimized and upgraded in the health state, and then the road test equipment is installed to collect the relevant information of the engine in operation of the vehicle, so as to provide the most accurate vehicle data for foreign programmers. Finally, the control system of the engine is read out through special equipment, and the objective information such as the read program, the log information of the road test, the reasonable needs of the riders, and the oil product of the vehicle configuration are transmitted to the foreign program providers to ensure the rationality of the program optimization.
Basically, every car owner who wants to brush the ECU will be very concerned about whether it will shorten the engine life. In fact, this is due to the fact that many people do not understand the meaning of upgrading the ECU, and the actual upgrade of the ECU means program optimization, which is the best adjustment of the program according to the matching engine to improve the energy efficiency ratio of the engine. As long as the ECU program is adjusted within a reasonable and correct range, it will not affect the life of the engine. For example, just like the W7 system of the computer we usually use, Microsoft constantly updates the W7 system from time to time, in fact, in order to make the operation of the W7 system safer, more convenient and smoother. Therefore, we will see that our W7 system will be automatically updated to the latest version from time to time. The ECU program is equivalent to an operating system, which provides reliable and stable working conditions for the engine. Switching to a good version of the program will make it work more efficiently.
The overall operation is about three hours, and the customized and optimized program has been implanted into the engine control system, and after passing the professional equipment test, the log information collection of the road test is carried out again, and the rationality and pertinence of the program optimization are revised;
The actual road test results are as follows:
1: Through the overall customization and optimization, the car can be felt more lighter at the moment of starting, the acceleration is always available, the acceleration feeling continues to be linear, and the phenomenon of power lag has been well improved;
Two: the shift logic is clearer and smarter, the shift is more positive and smooth, although the previous low-gear frustration has not been able to improve well;
Three: the sound is more deep and deep, Porsche 718 cayman 20T brush ECU upgrade to improve power shifting, cost-effective, and safety is very high.
Hotspot Engine Program As the saying goes, "Power is like money in your pocket, you can do without, 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.
