About the three forms of automotive electronic ECU

Let me tell you that some hidden functions of the car can be flashed out by flashing the ECU. First of all, let's talk about ECU. ECU is the control unit of the car, commonly known as the driving computer, which is equivalent to the human brain responsible for controlling the car's actions. Flashing the ECU is also called flashing the hidden. Generally, the parameters of joint venture cars are adjusted according to foreign countries, but when they arrive in China, some of the power is hidden according to road conditions and oil products. At this time, flashing the ECU can flash out the original horsepower and restore its original strength.

There are also some functions that are only available on high-end cars. In fact, mid-end and low-end models also have them. It’s just that manufacturers hide these functions in order to control consumption, and lock them without setting buttons. We can unlock and add this button by flashing the ECU, and it will become a high-end version, such as one-touch window lowering, one-touch window raising, cruise function, etc. to realize the modified version functions.

Let me tell you the advantages and disadvantages of flashing ECU. The advantage is to increase power and increase functions. Secondly, it can properly solve some problems. For example, if there is a problem with the tuning of some cars, flashing ECU can solve the problem of gear shifting and power disconnection. The disadvantage is that not all cars can flash ECU, and the 4S shop will no longer provide warranty after flashing ECU. In addition, the car after flashing ECU is likely to age too quickly and the value retention rate is too low. I have seen three forms of flashing ECU. Let me tell you.

First: The flashing method is also the most common one. It is like flashing the mobile phone system. It is a modification of the original factory setting program. Since it will not damage other hardware, it is relatively stable and is commonly used by many car owners.

Second: The plug-in type intercepts the signals of various sensors through implantation and makes modifications, which is a bit like a cheat. Since the performance of private car ECUs is getting more and more powerful, this method is difficult to operate. Just like Great Wall's H9, the power of the old model can be converted to the new model through an external plug-in ECU to increase the horsepower.

The last type of ECU replacement is more commonly used in competition mode, like modified cars, but it requires higher technical skills.

When it comes to flashing the ECU, you must consider carefully whether you can withstand the advantages and disadvantages of flashing the ECU to avoid unnecessary trouble and distress in the future.
