ECUFlashKit provides tools and software solutions for reading, editing, and flashing engine control units (ECUs). Our products are designed for tuners, DIY enthusiasts, and developers who want full control over their vehicles — whether for performance tuning, diagnostics, or research purposes.

We support all Siemens MS42, MS43, and MS45 ECUs. In addition, we’re actively developing support for motorcycle ECUs and newer BMW models to expand compatibility across more platforms.

Most setups require a K+DCAN or FTDI-based interface, a bench power supply, and optionally an OBD2 connector with open leads for bench flashing.

However, we also offer an all-in-one hardware bundle that includes everything you need to get started quickly and safely — perfect for anyone who wants a ready-to-use solution.
