Confirmed PIDs

Confirmed PIDs — Voge 900DSX (LX900-A / BMW F900 platform, Loncin 4M96001 engine)

Every request in this table has been verified to return a real, correctly-decoded value on this bike (not just "no error") via live on-bike testing with a Bluetooth ELM327 adapter. This should generalize to other bikes on the same BMW F900 platform (Voge/Loncin 4M96001), though exact values may vary by model year/ECU revision — verify against a real ride before trusting any of it.

This is the same list the app polls (BluetoothOBDManager.CONFIRMED_PID_MAP), and the app's own Bike Info tab shows a live version of it — a green/red/gray dot per row for whether the last request on the current connection actually matched what was expected, not just a static claim.

Headers used: 7E0 = engine ECU (Bosch ME17.8.10), 7E1 = ABS/IMU module.

Reference vehicle (via Mode 09, cross-checked with another OBD app — PID 0902/0904): VIN LLCVPX1A8RA150987, calibration ID 8814LX28502BLXMT. Worth checking against when cross-referencing another BMW F900-platform bike's CAN/DID data (e.g. the community CAN-ID spreadsheet) — different calibration revisions can shift layouts even on the same platform.

✅ Confirmed working

Standard OBD-II (SAE J1979, Mode 01/03)

Manufacturer UDS DIDs (7E1 header) are covered in Not working below — as of 2026-08-09 none of them have ever returned real data on this bike; see that section for how this was checked.

❌ Not working

All seven rows below were listed as confirmed in an earlier pass of this doc. Cross-checked 2026-08-09 against every real (non-simulated) ride ever recorded in the app's own database (55k+ records going back to 2026-08-01, excluding the day's 3 known-simulated test rides) — every one of these columns is exactly zero in every single real record, never once a nonzero value, which the diagnostic log's failures for the same requests corroborate.

Header	PID/DID	Signal	Response
7E0	2243F7	Gear	7F 22 31, even with a UDS Extended Diagnostic Session actively granted (50 03)
7E0	222503	ECU odometer	7F 22 31, same as Gear
7E1	222B05	Front brake pressure	NO DATA
7E1	222B06	Rear brake pressure	NO DATA
7E1	22D10D	Lean angle (bike IMU)	NO DATA
7E0	012F	Fuel level	NO DATA
7E0	015E	Fuel rate	NO DATA
7E0	43FE	Unmapped	7F 22 31, even with the session granted
7E0	43FF	Unmapped	7F 22 31, same as 43FE

Checking the recorded DB instead of just grepping the log for failures is what caught fuel level/rate and the two brake DIDs — a live spot-check earlier the same day had wrongly reported "yes, fuel level and rate work" going only off this doc's stale confirmed table. The extended-session hypothesis for 2243F7/222503/43FE/43FF was separately disproved the same day (session granted, 50 03, all four still failed identically) — root cause for any row above is still open.

Two related open leads, not request/response PIDs so they don't fit the table above:

• Lean angle broadcast on the raw CAN bus — 22D10D never answers on request (see above), but there's reason to believe the IMU also broadcasts lean angle passively on the bus without being asked. The app's raw CAN monitor (Bike Info) exists to capture and manually correlate this against known bike tilt, for anyone who wants to find the broadcasting CAN ID.
• Gear signal on the raw CAN bus — a 1-2-N-1 shift test against a passive CAN capture (2026-08-09) found no CAN ID with a clean 3-transition pattern matching the three shifts; the earlier 12B lead from a prior session's stall-event capture didn't repeat here either. Still unconfirmed.
• A completely different channel for fuel/gear/odometer, unexplored so far — the bike's own dash shows all three despite the OBD/UDS requests above never working, so it's getting them some other way. MOTO-HUB (a screen-mirroring app for Voge/CFMOTO/Zontes dashboards, unrelated project) confirms these dashboards have a T-Box (telematics unit) reachable over Wi-Fi Direct, separate from the OBD port - not something this app has ever tried talking to. Whether the dash also exposes anything over a direct Bluetooth link (rather than only Wi-Fi Direct to the T-Box) is unknown. Nothing implemented here yet - just a lead for whoever picks this up next.

How this list was built

Combination of: SAE J1979 standard PID scanning (sweepStandardPidSupport() in the app), manual UDS DID sweeps across the two confirmed-responsive headers (7E0, 7E1), and cross-referencing another OBD app's raw sensor dumps against real dashboard readings taken at the same time. PIDs that returned data but couldn't be correlated to a real, verifiable value on the bike are deliberately left out of this list rather than included as a guess. As of 2026-08-09, entries are also periodically cross-checked against the app's own recorded ride database rather than trusted from the original sweep alone - see Not working above for what that caught.
