Not recommended for: Flashing BDC, FEM, MGU, or any ECU in G-series (2019+).

BMW PSDZData Lite (commonly shortened to PSDZData Lite) is a compact, user-configurable dataset and toolset used by independent BMW technicians and advanced enthusiasts to perform coding, programming, and diagnostic operations on BMW vehicles. It is a derivative or subset of the broader PSDZData/PSdZData packages used with BMW factory-level tools (such as E-sys, ISTA/P, and other dealer-level software) to provide vehicle-specific coding files, ECU data, FA/VO (vehicle order/vehicle option) reconstructions, and programming payloads.
