Description
K-Line Flash Dumper is a lightweight Windows desktop application designed to read and save binary raw Flash memory dumps from Electronic Control Units (ECUs) using inexpensive USB KKL (VAG-COM / FTDI / CH340) diagnostic cables.
The application communicates over the KWP2000 (ISO 14230) protocol over K-Line, featuring a built-in KWP FastInit wake-up sequence, hardware echo cancellation, real-time memory streaming, and configuration persistence.
So far tested and works with this ecus:
- Motion SE08
Not working with:
- Delphi MT05.3 dual plug ecu
- Delphi MT05.2 dual plug ecu
