Bluetooth ELM327 OBD2 scanner: live engine data, fault codes and PDF reports
Turn your Android phone into a powerful OBD2 car scanner, Check Engine diagnostic tool and live engine data monitor. OBD2 Engine & Car Diagnostics connects to compatible Bluetooth OBD2 interfaces to read vehicle fault codes (DTC), monitor ECU sensors, record driving sessions and analyse engine performance. BLUETOOTH ELM327 ADAPTER REQUIRED To read real ECU data, you need a compatible Bluetooth ELM327 OBD2 adapter or supported equivalent, plugged into your car's OBD2 diagnostic port. The adapter is sold separately and is not included with the app. A phone alone cannot read ECU data. Compatibility depends on the adapter, vehicle and ECU. LIVE OBD2 DATA & CAR DASHBOARD Track supported engine parameters in real time: • Engine RPM, vehicle speed and engine load • Coolant and intake air temperature • Throttle position and intake manifold pressure • Mass air flow (MAF), fuel trims and fuel level • Fuel pressure and fuel rail pressure • EGR readings and adapter voltage • Other available OBD2 PID sensor values The app automatically detects which standard parameters your car supports. Missing readings are not treated as zero or confirmed faults. Configure a live dashboard with selected gauges. CHECK ENGINE LIGHT & CAR FAULT CODES • Read supported diagnostic trouble codes (DTC) • Inspect ECU and vehicle information • Check emissions readiness monitors • Review diagnostic context and fault information • Clear supported codes when appropriate Clearing an error code does not fix the underlying mechanical or electrical problem. DRIVING SESSIONS & HISTORY Record ECU measurements, timelines, charts, session events and statistics. Review saved sessions and diagnostic trends without reconnecting to the vehicle. GPS & PHONE SENSOR ANALYSIS When supported by your phone and permissions, capture GPS speed, acceleration, gyroscope, vibration and microphone-based measurements alongside OBD2 data. ADVANCED ENGINE ANALYSIS — PRO Use combined analysis to compare ECU and phone measurements, including GPS speed versus ECU speed and engine RPM versus microphone signals. Explore patterns involving engine RPM, speed, load, airflow, GPS, vibration and sound. Review supporting evidence, confidence levels and suggested follow-up checks. These are diagnostic observations, not confirmed mechanical diagnoses. CHARTS & PDF DIAGNOSTIC REPORTS Inspect time-based sensor charts, physical units and session statistics. PRO provides detailed PDF reports for saving, reviewing or sharing with your mechanic. FREE & PRO FREE offers core OBD2 features and live vehicle data. PRO unlocks advanced analysis, expanded history, replay tools, configurable dashboards and detailed reports. Choose monthly, 6-month or yearly PRO access, or a one-time Lifetime purchase. SUPPORTED CAR BRANDS & COMPATIBILITY Designed for vehicles supporting standard OBD2/EOBD, including compatible models from: • Volkswagen (VW), Audi, Skoda, SEAT, CUPRA • Ford, Opel, Vauxhall, BMW, MINI • Mercedes-Benz, Renault, Dacia • Peugeot, Citroën, DS, Fiat, Alfa Romeo • Toyota, Lexus, Honda, Nissan, Mazda • Hyundai, Kia, Suzuki, Mitsubishi, Subaru • Volvo, Jeep, Chevrolet, Jaguar, Land Rover In Europe, EOBD support generally applies to petrol cars from around 2001 and diesel cars from around 2004.
