Overview
ESys is a Windows-based engineering application used with an ENET or K+DCAN interface to code and adapt modules in BMW/Mini vehicles (F/G/I models and some newer). It communicates with vehicle modules via ISTA/P or directly using E-sys protocols. Coding changes are made by modifying VO/FA/FAac (vehicle order / factory order) or by writing new FA/VO values and flashing FA_DECODER or using FDL toolbox for single-channel edits.
