What is E-Sys?
E-Sys is the official engineering software used by BMW for coding, programming, and flashing Electronic Control Units (ECUs) in modern vehicles. Having the correct version of E-Sys is often critical for compatibility with your vehicle's software level (I-Level) and the PSdZData you are using.

What is PSdZData?
PSdZData contains all the necessary firmware and configuration files that E-Sys uses to communicate with and program the vehicle's modules. A full PSdZData library is required for most flashing operations.
