Data Cloning

Note : Before performing data cloning, it is necessary to backup and save the FLASH&EEPROM data of the original ECU and the external ECU. For specific operation steps, please refer to the previous chapter.
This function is mainly used for engine ECU data cloning of VW, Audiand Porsche, other models can complete data cloning by directly reading and writing data.

• Read and save the FLASH&EEPROM data of the original vehicle ECU and the external ECU.
• Click Data Processing on the main interface, and select Data Cloning in the pop-up window to enter the following interface
• Select the corresponding car model for data cloning. Follow the software prompts to load the FLASH & EEPROM data of the original vehicle ECU respectively
• Follow the software prompts to load the FLASH & EEPROM data of external ECU respectively.
• The system analyzes the anti-theft data and generates a clone data file, click Confirm to save it.
• Connect external ECU and ECU&TCU Programmer, write FLASH data of original ECU and saved EEPROM clone data into external ECU.
