When sourcing the latest PSdZData, users typically choose between two versions: Lite and Full. The PSdZData Lite version is the most common choice for "coding," which refers to changing parameters within an ECU to enable or disable features like auto-start-stop memory, video-in-motion, or digital speedometers. It is significantly smaller in size because it excludes the heavy "SGBM" files needed for flashing or updating the actual firmware of the modules. For those intending to "program" or flash ECUs to a newer software version, the PSdZData Full package is required, though it often exceeds 100GB in size and necessitates a stable power supply and an ICOM interface for safety.

The primary purpose of PSdZData is to provide the E-Sys software with the necessary translation layers to interpret the data stored in a car's modules. Without the correct version of these data files, users often encounter errors such as "trimmed CAFD" (Configuration Address Files) or an inability to connect to newer vehicles that have received recent dealership software updates. As of May 2026, the latest PSdZData versions are designed to support the newest I-Levels (Integration Levels) found in the latest G-series and upcoming electric models.
