Working with the Module
To begin, load the EEPROM file by clicking the “Open EEPROM” button.
During loading, the file size is checked to ensure it is valid. 
After the data has been loaded successfully, you can begin working with the immobilizer data.
The following data can be modified: VIN, ECU CS, CS2, ECU MAC, EZS MAC, Slave ECU MAC, PowerClass, KeyCount, Keys, and immobilizer status.
Immobilizer data can be edited manually or by copying values into the corresponding fields.
After making the required changes, save the data by clicking the “Save EEPROM” button. The entered data is validated before it is saved.
Important Note:
The module uses Immo 4 data.
