Honda Customizer 3.4.2 — decoder identification for cluster research
The XP connection report now reads the CAN decoder version text from FYT field 1005, in addition to the existing numeric profile and SYU Android service version. The previous callback parser ignored string-only replies.
On exact profile 0x4012A, connect and open Report → Copy. If FYT supplies the decoder version, it appears on its own line. Missing text remains unavailable. The report explicitly labels the version as service-reported and potentially cached; it does not confirm the current physical hardware identity. Reconnection clears the previous session's text. This subscription sends no vehicle command.
This release does not add extra physical cluster customization. The source archive now includes an offline derivation of 48 conditional OEM packets covering meter configuration, ambient-color options, turn-by-turn display and tachometer display. Their XP passthrough mapping remains unresolved and they are not included in the app as executable presets.
Validation: 89 Java tests and 11 Python tests; release lint has no errors. Coverage includes string-only callbacks, malformed payloads, unavailable text, stale-session rejection, and no vehicle writes during identification. No physical head unit or vehicle is connected to the development environment.
Version code 14, retaining the existing signing certificate. Install Honda-Customizer-3.4.2-FYT.apk or use the in-app update check.
