Biketune turns a supported ELM327 / OBD-II adapter into a full motorcycle diagnostic and coding tool. Connect over Bluetooth or Wi-Fi to read fault codes, watch live engine data, reset the service reminder, and code your bike the way a dealer would, without booking a workshop slot. WHO IT'S FOR Riders who do their own maintenance. Change your oil, then reset the service reminder yourself, no dealer appointment and no fee just to clear the wrench. DIY mechanics who would rather diagnose a fault than guess at it. And anyone who wants to change a setting the dealer charges for. SCAN FOR FREE • Read trouble codes across every reachable ECU: engine, ABS, cluster, chassis, body. • Live engine data: RPM, road speed, coolant and oil temperature, lean angle, twist-grip, gear and battery, in metric or imperial. • All Sensors and Freeze Frame: every parameter, plus what the engine was doing when a code was set. • Advisory codes and Programming Info: VIN, ECU name, calibration ID, BMW chassis code and part numbers. • Tire-pressure monitoring: live TPMS status per wheel. • Shareable fault reports: turn any scan into a clean summary to send to a mechanic. • Demo mode: try every screen without an adapter, anywhere. UNLOCK THE WORKSHOP WITH PRO A single one-time purchase, no subscription, adds every write path and power tool: • Service Reset: write next-service distance, date and bike clock back to the cluster. • Clear trouble codes after a repair. • Coding: change cluster and accessory settings in plain language, from daytime running lights to heated grips to tyre-pressure thresholds in bar or psi. Options vary by bike and fitted equipment. • Adaptations: read stored adaptation values from the cluster and engine. • Actuator Tests: command outputs and actuators directly, safety-gated. • Control Units: drill into each ECU for its own codes, live data, coding and tests. • ABS Data, Accessory Outputs (ZFE), live charting, Data Explorer and Raw Console. COMPATIBILITY • Generic OBD-II: any motorcycle or car that speaks SAE J1979 over CAN (most post-2008 vehicles). • BMW® motorcycles: the deepest support. Modern CAN bikes get reads, live data, coding, adaptations and service procedures: S 1000 RR / R / XR, M 1000 R / RR, R 1200 / 1250 / 1300 GS and RT, R nineT and R 12 families, R 18, F 750 / 800 / 850 / 900, K 1600. Coverage extends to the G-series singles, the C-series and CE scooters, the four-cylinder K bikes, the air and oilhead classics, and BMW-era Husqvarna. Pre-CAN K-line bikes get a dedicated legacy profile. ADAPTER SUPPORT For the full BMW feature set, use a genuine STN-chip adapter: UniCarScan (UCSI-2100), OBDLink CX / SX, or the verified Veepeak OBDCheck BLE+ all pass the extended-addressing and multi-frame checks that coding and service writes need. vGate iCar and most clones handle generic OBD-II reads, but cheaper ones skip extended-addressing, so BMW writes will not work on them. On pairing, Biketune shows the adapter's expected tier and can test every feature against your exact bike first. HONEST ABOUT WHAT WORKS Depth depends on your bike and adapter: generic OBD-II reads work on most post-2008 vehicles, while BMW-specific writes need a BMW bike and proper UDS support. Try Demo mode and the in-app compatibility check before unlocking Pro. PRIVACY Your garage, sessions and diagnostic data stay on your device; your VIN, fault codes and live readings are never sent to us. Optional Sign in with Apple enables iCloud sync of your bike list and adapter pairings through your private iCloud key-value store, not our servers. We use IDFA-free analytics and crash reporting to improve the app, with no ad tracking and no App Tracking Transparency prompt. Available in 11 languages, with a native Liquid Glass interface for iOS 26. NOT AFFILIATED WITH BMW MOTORRAD. Biketune is an independent diagnostic tool; model and chassis names describe vehicle compatibility only. All trademarks remain the property of their respective owners.
