• Retrofit guides that were written in 2017-2019 – They reference exact CAFD names (e.g., CAFD_00002A6F_051_000_030) which disappear in later PSdZData.
• Offline flashing of older F-series cars without risking incompatible updates.
• Stable coding for features like anti-dazzle, where newer PSdZData may change parameter structures.
• Users without tokens – Later E-sys versions (3.30+) require launchers with paid tokens or time-limited trials.
