Car modification, please answer the expert, what hardware and software are needed to modify the ECU of the car? Briefly talk about how to change the program. What professional knowledge is needed?

Required hardware: Programmer used to realize communication (reading and writing) between computer and ECU. There are roughly several kinds:

1. welding equipment +EEPROM programmer (that is, the machine used to brush the BIOS chip of the computer motherboard when the CIH virus is popular); This hardware can be used in vehicles that need to remove EEPROM from ECU for reading and writing.

2.OBDII programmer; Most Volkswagen models support OBDII reading and writing ECU. This mode is more convenient without disassembling ECU.

3.BDM programmers; Many BMW cars use this and need to disassemble ECU.

4. Boot mode programmer; Many cars in France and Italy will use ECU for reading and writing, so it is necessary to disassemble ECU.

Where 2, 3 and 4 are the same programmers connected to the computer in use, but the interfaces are different (OBDII/BDM/ Boot Mode).

Required software:

1. The programmer is purchased with application software of different programmers and installed under WINDOWS.

2. Edit the ECU program (engine working condition database) with M.A.P editing software (for teachers only, which is rarely seen in China). WinOLS of EVC company is commonly used, and some software of checksum tool is needed-ECU can be adjusted by itself with this kind of software.

Required professional knowledge:

0. Application level: After the equipment is bought, just look at the illustrated instructions, know how to disassemble and read the ECU, what precautions are there, and the common programmer types corresponding to each model. More than 95% of the businesses engaged in ECU business in Greater China (including Hong Kong, Macao and Taiwan) are at this level.

1. Entry-level: Understand the working principle and common working conditions of the engine, use common sensors, monitoring instruments and M.A.P editing software, adjust the ECU files of the original vehicle in a small range, and set up common jumper computers (such as ECU modification of N/A vehicles with TURBO).

2. Expert level ... the main teachers in Europe and technical support personnel involved in automobile sports.

Process of replacing ECU

1. Read the original vehicle ECU file.

2. Modify to obtain the ECU upgrade file.

3. Write the upgrade file into ECU.

4. Trial operation, debugging is ok, if there is any problem in debugging, modify it from the second step.

1 gamemaster0430 on the floor is basically true. Some people in China know the technology and will change it, but others don't make civilian cars.

The second floor is basically propaganda. ...

Merchants' methods are similar. There is no need to "distinguish and exaggerate" simple and organized facts ... the mysterious atmosphere is too heavy, which is actually unfavorable for cultivating the market.
