PSdZData — Full ECU Programming Data Pack for E-Sys - BMW PSdZData v4.55.21 FULL — flash-ready ECU data pack for E-Sys/ISTA; more than Lite.

BMW PSdZData — FULL package for programming & flashing with E-Sys

What it is
PSdZData is the official BMW ECU dataset used by E-Sys/ISTA to code, program and flash modules on F/G/I-series vehicles. The FULL edition contains the complete set of firmware payloads (SWFL/BTLD), CAFD/FAFP, BLP and related metadata required to update control units — not just code them.

Why FULL (vs Lite)
  • FULL: includes firmware files for...

Bin updated PSdZData — Full ECU Programming Data Pack for E-Sys with a new update entry:

PSdZData Lite — Add-on for the Full package (F/G/I-series coding)

PSdZData Lite v4.55.30 — what’s new
  • Latest 2025 PSdZ data refresh with extended coverage for recent F/G/I-series platforms.
  • Updated CAFD/FAFP metadata and mappings for smoother FDL coding workflows.
  • Optimized package structure for faster indexing and lower disk footprint.
  • General stability tweaks and minor clean-ups.

About the Lite package
  • Intended for FDL coding only. Flash files (SWFL/BTLD/IBAD) are not included.

Glad it's useful!

Just a quick tip for those new to this: make sure you extract the content correctly so E-Sys can find it. The folder structure should look like this in your installation directory (usually C:\Data):

Code: 
C:\Data\psdzdata\mainseries\
C:\Data\psdzdata\swe\
...

Also, a reminder on which version to grab:
  • Lite Version: Sufficient for all coding tasks (VO/FDL).
  • Full Version: Only needed for flashing modules (firmware updates).

If you encounter "Trimmed" CAFD files, ensure your launcher mapping is up to date for v4.55.21.
 
Bin updated PSdZData — Full ECU Programming Data Pack for E-Sys with a new update entry:

PSdZData 4.57.30 Release: Full & Lite Packs, BMW E-Sys/ISTA 2026

PSdZData 4.57.30 is now available in two variants: Full and Lite.

Choose your package:
  • Full — complete dataset (recommended for programming/flashing scenarios).
  • Lite — reduced size (recommended for coding/common use where Full isn’t required).

I am trying to download this to use with ISTA. The goal is to disable the adaptive mode for my headlights on my 2014 528i. would using lite for coding work or will I have to download the full?
 

For what you are trying to do, PSdZData Lite is perfectly sufficient.

The difference is simple:
  • Lite: Contains all the CAFD files needed for Coding (changing settings, enabling/disabling features like your adaptive headlights).
  • Full: Contains the actual firmware files (swfl, etc.) needed for Flashing (updating the ECU software version).

Since you are looking to disable a feature (which is either VO Coding or FDL Coding), you do not need the massive Full download.

Note: While you mentioned ISTA, E-Sys is generally the preferred tool for disabling specific options or custom coding.

One more question. Sorry I am new to this. Will I just be downloading file 4.55.30 or do I need to download all the other versions as well?

No need to apologize!

You only need to download the latest version available.

You do not need the previous versions. The PSdZData folder is a complete replacement, not an incremental раtсh that stacks on top of older files.

Steps:
  1. Delete your existing C:\Data\psdzdata folder (or rename it to psdzdata_old as a backup).
  2. Extract the contents of the single new version you downloaded.
  3. Place the new files into C:\Data\psdzdata.

This ensures you have the cleanest setup for coding.
