X431 ECU Programmer and X431 PC Adapter support the same function. The difference is that PC Adapter needs to work with X-431 X-Prog3, and they work with different PC software. Except that, others are similar.


In summary:

All above ECU Programmers have operation instruction and wiring diagram in the software.

These tools are a connection device between the laptop and the car’s ECU (only DC706 can work alone), which is used for reading and writing the ECU’s memory in different methods. Depending on the type of the car or ECU, the method of reading or writing the file can be different.


Only Kess3 and DC706 can support OBD, Bench, and Boot three modes. Others don’t support OBD mode.

Kess V3 supports the most protocols, but it’s the most expensive, and needs to buy the corresponding protocol.

FC200 and Multi-Prog are more cost-effective to choose. Multi Prog software is updated frequently and quickly.

For beginners with weak hands-on ability, obd2 and bench modes are suitable for use, and for the customers with strong hands-on ability, they can do all modes.


Besides, CG100X, CG100 Prog III, and Yanhua ACDP-2 also support ECU cloning for some car models.


As a beginner, it’s important to start with simple modifications and work your way up. Make small changes to your ECU settings and see how they affect your engine’s performance. As you become more experienced, you can gradually increase the complexity of your modifications.

Here is regular operation guide:

Step 1: Read the original ECU

Use a professional ECU programmer to read the original data stored on the ECU.

Step 2: Save the original ECU’s data

Save the original ECU to a computer or other storage device. This is known as “dumping” the original ECU.

Step 3: Prepare the replacement ECU

Prepare a replacement ECU to receive the data from the original ECU for the cloning process. This may involve wiping any existing data from the replacement ECU or making any necessary hardware modifications.

Step 4: Write the original ECU’s data to the replacement ECU

Write the data from the original ECU to the replacement ECU. This process is known as “flashing” the replacement ECU.

Step 5: Verify the replacement ECU

The replacement ECU is then connected to a diagnostic scanner and the software and data on the replacement ECU is verified to ensure that it matches that of the original ECU.

Step 6: Install the replacement ECU

After cloning, install the replacement ECU in the vehicle and connect to the engine management system. It is thoroughly checked to ensure that everything is working correctly and is optimized to the vehicle’s requirements.
