What it is
A compact Windows application that works with Delphi DCM3.4 ECUs used in many Renault/Dacia models. It processes the external 95640 EEPROM dump to prepare a unit for service or replacement.
Main functions
- Virgin Patch: clears immobilizer pairing data in the 95640 so the ECU can be adapted again after repair/replacement with OEM tools.
- KM Reset (service use): resets the mileage value stored in the ECU when legally replacing modules to keep vehicle records consistent.
- PinOut helper: quick-access board photo to locate the 95640 for in-circuit reading/writing.
How to use (typical workflow)
- Read the ECU’s 95640 EEPROM with your programmer (e.g., VVDI, Xprog, TL866, etc.). Save the BIN.
- Open the tool → Upload BIN File.
- Choose Virgin Patch or KM Reset and let the app process the file.
- Write the new BIN back to the 95640. Re-install the ECU and perform the required coding/learning with your diagnostic equipment.
Compatibility highlights
- ECU family: Delphi DCM3.4 (95640 external SPI EEPROM).
- Platforms: Common on Renault/Dacia with 1.5 dCi (K9K) and related trims (e.g., Clio, Kangoo, Megane, Logan, Sandero, Duster — verify label/part numbers).
- File format: raw BIN read of the 95640.
Notes & tips: Always keep verified backups of the original EEPROM. Ensure stable power when flashing. After virginizing, complete pairing with dealer-grade or equivalent diagnostic procedures.
