This encompasses critical information such as the ISN, Vehicle Identification Number (VIN), and other essential data. This unique feature empowers users to seamlessly transfer the internal EEPROM data to another ECU, ensuring the continued smooth operation of the vehicle. It's important to note that this process requires the internal flash of the donor ECU to be in good condition and compatible.

This selective data transfer capability proves invaluable when users seek to harness performance-mapped or tuned internal flash data from one ECU and apply it to another. By facilitating the transfer of specific internal data, HexProg II streamlines not only the ECU Replacement process but also opens avenues for customization and optimization. This allows for the integration of tailored performance data, contributing to a more personalized and enhanced driving experience.

Moreover, HexProg II extends its utility beyond ECU Cloning and selective data transfer—it serves as a proficient tool for ECU Repair. In instances where the ECU encounters issues or malfunctions, HexProg II can be employed to rectify problems, contributing to the overall maintenance and longevity of the vehicle's electronic systems. In essence, HexProg II emerges as a multifaceted solution for managing EDC17C50 ECUs in BMW and MINI vehicles. 

In addition to On-Bench and Boot functions, the EDC17C50 ECU is also supported in OBD Mode within HexProg II Tuner software. While On-Bench and Boot Modes offer the capability to clone and write the entire dataset from the ECU, the OBD Mode focuses on selectively modifying map portions from the EDC17C50. This feature proves to be particularly beneficial for Chip Tuning and remapping, enabling users to enhance or tailor specific performance aspects of the engine.

The On-Bench and Boot Modes excel in their comprehensive approach, allowing for the duplication and writing of the complete data from the ECU. This is particularly useful when a user needs to transfer the entire set of information, ensuring a seamless transition between ECUs. Whether for ECU Diagnostics, ECU Repairs, or ECU Customization, these modes provide a robust solution.

On the other hand, the OBD mode offers a more targeted approach, enabling users to modify specific map portions within the EDC17C50. This focused functionality becomes a key asset in the realm of Chip Tuning and remapping. By accessing and adjusting these map portions, users can optimize the engine's performance parameters, achieving a tailored and boosted output.

In the OBD mode, HexProg II Tuner software features a functionality known as Virtual Read. This option empowers users to download the stock map portion of the internal flash data of the ECU directly from the Microtronik server. The OBD Virtual Read file obtained through this process serves as a valuable resource for tuning and remapping purposes, allowing users to make targeted adjustments to the engine's performance parameters. What sets this feature apart is its seamless integration into the tuning process, as users can write the modified Virtual Read file back to the ECU in OBD mode, streamlining the tuning experience.

A notable advantage of the Virtual file is its origin from the Microtronik server, ensuring that it represents the stock configuration. This proves invaluable when users need to rectify undesirable modifications or tuning tweaks made to the ECU. By writing back the Virtual file in OBD mode using HexProg II Tuner software, users can effortlessly restore the EDC17C50 to its factory-stock state.

Furthermore, HexProg II Tuner software automatically performs checksum verification on modified Virtual Read files during the OBD writing process. This built-in functionality enhances the Chip Tuning process, ensuring the integrity and accuracy of the modified data. The software's capability to manage this checksum automatically adds an extra layer of reliability to the tuning experience.

Notably, HexProg II Tuner software extends its support to BMW models and MINI EDC17C50 ECUs across Bench, Boot, and OBD modes. This comprehensive compatibility ensures that users can employ the software across various scenarios, providing flexibility and versatility in addressing the unique ECU Tuning and ECU Remapping needs of these specific vehicle models.

In essence, the Virtual Read feature in OBD mode, coupled with the automatic checksum verification, positions HexProg II Tuner software as a sophisticated and user-friendly tool for Chip-Tuning BMW and MINI EDC17C50 ECUs. Whether in Bench, Boot, or OBD modes, the software offers a holistic solution for enthusiasts and professionals seeking to optimize and customize engine performance with precision and ease.
ECU Cloning stands as a pivotal process in the realm of automotive electronics, providing a crucial function that goes beyond mere duplication. Its significance lies in the preservation of the entirety of original settings and calibration data embedded within the vehicle's Engine Control Unit (ECU). This meticulous preservation ensures that the vehicle can continue to operate seamlessly without necessitating extensive reprogramming efforts.

Below are the detailed steps for cloning EDC17C50 ECU:

  1. Preparation: Before starting the ECU Cloning process, ensure you have the necessary tools and equipment. You'll need Hexprog II hardware and Hexprog II Tuner Software with valid ECU Cloning license. You must use Hexprog II Tuner software to check the wiring diagram of the ECU, and arrange soldering equipment and stay wires as necessary.
  2. Accessing Bench Mode: Connect ECU On Bench using appropriate cables and connectors and ensure the connection is secure. (This ECU can also be clone in Boot Mode)
  3. Reading Original ECU Data: Once the connection to the ECU is established, Hexprog II hardware, combined with Hexprog II Tuner software, is used to 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: 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: With the new ECU prepared, the next step is to use Hexprog II hardware and Hexprog Tuner software 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.

In essence, ECU Cloning serves as a safeguard for the intricate configurations and calibrations that define the optimal functioning of the vehicle. By creating an exact replica of the ECU with all its inherent settings intact, this process eliminates the need for laborious and time-consuming reprogramming tasks that would otherwise be required to restore the vehicle to its factory state.
