  1. Preparation: Before starting the cloning process, you'll need Hexprog II hardware and Hexprog II Tuner software with valid ECU Cloning license. Wiring diagram of the ECU is in the software itself, arrange soldering equipment and stay wires as necessary.
  2. Accessing Boot Mode: As we preferred this ECU to be cloned in Boot Mode, open the ECU and establish a connection to its internal circuitry along with external connections. Boot and signal wires given in Hexprog II software, and it requires a delicate touch to avoid damaging any components.  This ECU also can be cloned in Bench Mode but if ECU part number not matching then it should be clone in Boot Mode Only. (This ECU can be read by Bench Mode and OBD too)
  3. Reading Original ECU Data: Once the connection to the ECU is established, read and extract the data from the original ECU. It is possible to read internal flash separately in .bin format that can be used for modification and Chip Tuning. This data contains essential information about the vehicle's settings, calibration, and configurations
  4. Creating a Backup: The user needs to use the backup button to back up the whole ECU data. After successfully reading the data from the original ECU, backup files are created. This backup file contains all the information required to clone the ECU accurately. It is essential to store these backup files safely as it serves as the foundation for the cloning process.
  5. Preparing the New ECU: If the goal is to clone the ECU onto a new or refurbished one, the new ECU must be prepared. This involves ensuring that the new ECU is compatible with the vehicle and in working condition.
  6. Restoring Data onto New ECU: With the new ECU prepared, the next step is to restore the original backup file onto the new ECU. This process transfers all the original settings and configurations to the new ECU, effectively creating an identical copy of the original. Before restoring the original data, we recommend users to make a backup of new or donor ECU for safety concerns in the future.
  7. Testing and Verification: After the cloning process is complete, it's essential to verify the functionality of the newly cloned ECU. The vehicle should be tested to ensure that all systems are working correctly and that there are no error codes or malfunctions.
  8. Finalization: Once the cloned ECU is verified to be functioning properly, the ECU can be securely reinstalled in the vehicle. It is crucial to ensure that all connections are secure, and the ECU is properly seated.
