CMD Flash is a professional ECU read/write tool from CMD (Czech company) that focuses on OBD protocols, particularly for BMW, VAG Group, Mercedes-Benz, and a range of Asian manufacturers. It is well regarded for its coverage of BMW N-series and B-series engine ECUs.
CMD Flash operates on a credits-per-operation model and connects to the vehicle via OBD. It is particularly valued for BMW MEVD17.2 (N20, N55) and BMW B-series (B48, B58) coverage where it offers reliable OBD read/write without requiring bench access. The software is updated frequently with new protocols.
