NCD/CAFD Tool is a coding analysis utility used with BMW F/G-series workflows. It helps read and view ECU coding data, decrypt CAFD where applicable, compare NCD files, and review FA/FP information against PSdZData mappings for safer, traceable edits. Highlights NCD/CAFD viewer with verbose parameter names and translation options One-click NCD Compare to visualize coding differences between files Decrypt CAFD and inspect trimmed CAFD for supported datasets FA / FP viewers and FA Compare for retrofit planning and validation FA-CAFD calculator to suggest affected functions based on selected options Works with local PSdZData path and signature key for mapping Package contents NCD KEY\ CafData.dat language.en.xml NcdCafdTool.exe NcdCafdTool.exe.Config PSdZdata.dat Un.lck Compatibility notes Intended for BMW coding workflows that use E-Sys and PSdZData. Feature availability varies by I-Step level, CAFD version and the completeness of the local PSdZData set. Use results as guidance and verify against the target vehicle’s FA and SVT before applying changes. Basic usage Point the tool to your local PSdZData folder and load NCD/CAFD or FA files Use [NCD Compare] to review differences, then confirm values in E-Sys Open [FA / FP] or [FA-CAFD] to evaluate option impacts on coding Export notes and keep full backups before any vehicle session Apply verified changes using your standard, approved coding procedure
