So, how can you get version v.4.27.20 to work successfully for your coding projects? The key is strict compatibility. PSdZData Lite is fully functional for all coding tasks, but only if paired with a compatible version of the E-Sys software. An older E-Sys version cannot interpret newer PSdZData structures, and a newer E-Sys version will not have its full feature set if paired with an outdated PSdZData.

Because the firmware files are absent, the Lite version is much smaller than the full PSdZData – around for version 4.27.20, while contemporary Full versions are well above 200 GB. This makes it an ideal choice for owners and independent technicians who only need to code their cars and have no intention of performing complete ECU software updates.
| | Avoid v42720 Lite IF: | |-------------------------|------------------------------| | You only code (FDL/CAFD) | You need to flash ECUs (DME, DSC) | | You have E-Sys 3.33+ | You are using INPA or Tool32 (needs Full) | | You work on 2018-2023 G-series | You work on electric iX / i4 (needs v4.33+) | | You have a slow internet connection | You are a professional flasher (buy OEM) | An older E-Sys version cannot interpret newer PSdZData
Download process (step-by-step, assuming an available archive)
If you use both (diagnostic tool) and E-Sys (coding tool), you can save up to 20 GB of storage space by linking your folders. Instead of copying a second copy of PSdZData into your C:\Data folder, use a Windows directory symbolic link:
mklink /d "C:\Data\psdzdata" "C:\EC-Apps\ISTA\PSdZ\data_swi\psdzdata" Use code with caution.
If your only goal is to unlock hidden functions, change personal settings or adapt retrofitted parts, the Lite version is the tool you need. Typical tasks include:
