Supported CAS1 Modules & Processors:
This tool is designed to work with dumps from the following CAS1 processors (masksets) and EEPROM sizes:
- 4KB EEPROM Dumps: for modules with 2K79X and 0L01Y (MC9S12DG128/256) processors.
- 2KB EEPROM Dumps: for modules with 0K50E (MC68HC912DG128A) processors.
Compatible EEPROM Programmers:
To read the data from your CAS1 module and write it back, you will need a compatible hardware programmer. Commonly used programmers for this job include:
- XPROG-M
- UPA-S (UPA-USB)
- Orange5
- VVDI Prog
- R270+
How to Use:
- Read the EEPROM data from your CAS1 module using a compatible programmer.
- Click "Open File" in the CAS1 Editor and load your saved dump file.
- Use the dedicated "Change" or "Reset" buttons to modify the ISN, VIN, or Mileage.
- Click "Save" to save the modified EEPROM file.
- Write the new, modified file back to your CAS1 module using your programmer.
Disclaimer: This is a powerful tool intended for educational and legitimate repair purposes. Always create and verify a backup of your original EEPROM file before making any changes. The user is fully responsible for their use of this software. Modifying a vehicle's mileage may be illegal in your country or region.
