Car computer ECU upgrade knowledge[汽车维修常识]

carThere are generally two ways to improve the motivation:
1. Make mechanical modifications, such as replacing high-performanceSpark plug,exhaust pipe, Install high-flow air grids, etc.;car repairMaintenance net
2. Another way is to upgrade the software of the engine computer to tap the potential power of the car.
The computer chip is a patented program that modifies the computer chip through the input of the car engine ECU, so that each car will increase the horsepower and torque by 10-35% without increasing fuel consumption and being fully consistent with the original diagnostic system, and is useful for the start of the car. The connection of power during overtaking and shifting has been greatly improved.
What exactly is a car computer chip?
I believe that anyone who has a superficial concept of home computers knows that the reason why a computer can do all the work is entirely due to a central processing unit (CPU, or chip) that is only the size of a normal matchbox. The performance of the central processing unit directly affects the computer’s performance. performance. Its system program can be upgraded from windows98 to windows2000.The location of the car’s computer chip is in the car’s engine computer (ECU-Electronic Control Unit). In fact, its function is the same as that of a home computer; the program in the chip controls the engine’sRotating speed, Fuel supply 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 maximum speed setting, engine over-turn fuel cut-off device , Intake air flow, knocking feedback, overpressure and lifting or setting safety limit speed, etc. This is the computer chip.
Why upgrade the computer chip?
Because the products of computer manufacturers are supplied to the world, that is to say, their computers have to adapt to the gasoline quality, temperature, atmospheric pressure, road conditions, etc. of each country-so the programming can only depend on versatility, and for Sex is not strong. The power of the computer is fully released, making the working state of the engine more accurate. Thereby improving the combustion efficiency of the entire engine, so that horsepower and torque are improved! Simply put: it is to tap the potential power of the car and give play to the best performance of the vehicle! Take the Supra, Toyota’s leading sports car, as an example. In Japan, which has the highest horsepower limit, the original manufacturer’s highest horsepower of the car is only 280 horsepower. However, after the car is imported into North America where there is no maximum horsepower limit, it will not undergo any modification at all. After adjusting only for the original computer, the maximum horsepower value can be instantly increased to 320 horsepower. The difference of 40 horsepower is enough to prove how much the car computer affects the vehicle.
In addition, the computer chip modification can also eliminate the original factory's speed limit on the vehicle, increase the upper limit of the engine speed (delay the timing of the fuel cut) and increase the original factory set performance output. In this way, performance improvement will not be a problem.
The significance of computer chip upgrade?
At present, the overall power performance is improved without affecting the fuel consumption (according to the owner of the car, "fuel saving" is the other biggest and most obvious benefit), without affecting the return to the original factory warranty, and without affecting the annual inspection of the car. We all know; if the computer is not upgraded to a certain degree, the product that is modified will not be able to exert its maximum performance. For example, we modified an exhaust pipe and increased the horsepower by 6 horses, but the computer may reach 10 horses after the upgrade. This is the added value of upgrading your computer.
How to upgrade the computer chip?
There are three ways to upgrade the computer chip, and different construction methods can be used for different models; below we introduce these three construction processes; the first one is to directly enter the new program on the original car’s diagnostic seat without dismantling the car. Anything, we call it "diagnostic block modification method". It writes the modified program directly from the diagnostic socket through a CustomerKey (the decoding socket that enters the original factory system has the function of a chip) and a special connection device, and the original program is stored in the CustomerKey at the same time. The entire construction process only takes 30 minutes. This construction method is suitable for Audi A4 1.8T,BMW,Benz, Citroen, Opel and other models; the second construction method is the traditional chip removal, that is, first remove the original chip and then solder it on a decoding base (equal to the key to enter the original system), and pass the modified program Write a new chip into the dedicated reader and reader, and then put the new chip into the decoder, and you’re done. The entire construction process takes about 40 minutes. This construction method is suitable for European and American models; the third type of construction The method is simpler. It uses a special adjustable computer to work with the original computer to achieve the function of the correction program. The construction can be completed in about 1 hour. It is mainly suitable for Japanese models.
