A new user report today confirms that Xhorse Multi-Prog can successfully read and write the PSA Magneti Marelli G6.14 ECU, a unit commonly found in older Peugeot and Citroën vehicles.
Magneti Marelli G6.14
The Magneti Marelli G6.14 is an early-generation Engine Control Unit (ECU) widely used in PSA vehicles, especially models equipped with the 1.4L KDX (TU3MC) engine. This ECU manages core engine functions such as fuel injection and ignition timing.
Typical vehicle applications include older Peugeot and Citroën models, with common ECU part numbers such as:
9618087780 – G6.14 0D01
9623757180 – G6.14 0D02
Test Details
MCU: MC68HC11A1
ECU Model: Magneti Marelli G6.14
Tool Used: VVDI Multi-Prog
Operation: Read & Write
Result: Successful
Using Xhorse Multi-Prog, the MCU data was read and written without issues, demonstrating stable communication and reliable performance on this older ECU platform.
Comparison with Other Tools
In the same test environment:
Autel XP400 with APB Adapter ❌ failed to read the ECU
This highlights a clear advantage of Xhorse Multi-Prog when dealing with certain legacy PSA ECUs and MCUs like the MC68HC11A1.
Practical Notes
Soldering is required, but the process is not very difficult for technicians with basic ECU bench experience.
Care should be taken during soldering to avoid damaging pads or traces, especially on older ECU boards.
