Launch X431 ECU & TCU Programmer – Standalone PC ECU/Transmission Read & Write, EEPROM/FLASH Backup, Data Cloning & IMMO-Off Programming Tool
The Launch X431 ECU & TCU Programmer is a professional standalone programming device designed for direct ECU and TCU reading, writing, backup, restoration, cloning and BENCH programming through a Windows PC.
Unlike the X-PROG3 PC Adapter, this device is the main programming hardware and does not require X-PROG3 or an X431 diagnostic tablet for its standard PC workflow.
It is designed for ECU repair specialists, transmission workshops and automotive electronics technicians who regularly perform module replacement, cloning, EEPROM/FLASH operations and data processing.

The X431 ECU & TCU Programmer is itself the programming hardware, while the X-PROG3 PC Adapter only connects an existing X-PROG3 to PC software.
🆚 ECU Programmer vs Diagnostic Scanner
| ECU & TCU Programmer | X431 Diagnostic Scanner | Main Purpose |
|---|---|---|
| ECU / TCU Read & Write | DTC Diagnostics | Programming vs Diagnostics |
| EEPROM / FLASH | Full-System Scan | Module vs Vehicle |
| ECU Cloning* | Live Data | Different Workflow |
| TCU Cloning* | Active Tests | Different Function |
| BENCH Programming | Service Functions | Module Programming |
| Data Processing | ECU Coding* | Complementary Tools |
| PC File Management | Vehicle Diagnostics | Different Platforms |
The ECU & TCU Programmer is a specialised programming tool, not a replacement for a full-system diagnostic scanner.
⚠️ Important Compatibility Information
Verify the exact ECU / TCU family and hardware/software number
Follow the Launch connection diagram exactly
