OpenOBD vs TScanPro

OpenOBD turns your iPhone into a real-time car dashboard. Connect any ELM327 OBD2 adapter (Bluetooth or Wi-Fi) and see what your car is really doing — live. LIVE ENGINE DATA • Speed, RPM, coolant temperature, intake, throttle, engine load, battery voltage and more • 50+ sensors with gauges you pick and reorder yourself • Instant and average fuel consumption • Tap any gauge for a live 60-second chart CARPLAY • A live 8-tile dashboard on your car's built-in screen • Start and stop trip recording without touching your phone DIAGNOSTICS • Read and clear fault codes (DTCs) with plain-language explanations • For common codes: what it means, how urgent it is, what to do next • Emissions readiness monitors before an inspection • Freeze frame — the sensor values from the moment the fault occurred • Vehicle info: VIN, fuel type, supported sensors TRIP LOGGING • Automatically record your drives with the GPS route on a map • Keeps recording in the background, even with the screen locked • Distance, duration, speed and fuel for every trip • Export any trip as CSV or GPX CAR HEALTH TOOLS • Battery and charging test: state of charge, alternator and cranking check • Diesel and DPF pre-check from standard, read-only OBD evidence • Used car check before you buy • Measure 0-100 km/h acceleration and 100-0 km/h braking • Live alerts for overheating and low voltage, in plain language BUILT FOR DRIVERS • Beautiful dark interface designed for the car • Over 40 languages, metric and imperial units • Works with affordable ELM327 adapters — no subscription, no account, no ads • Your data stays on your phone TRY IT WITHOUT HARDWARE • Tap Connect, then Demo Mode, to explore every feature with simulated live data OpenOBD is not affiliated with any car manufacturer. An OBD2 adapter (sold separately) is required to read data from your vehicle. Most petrol cars built after 2001 and diesels after 2004 are supported. The battery, diesel and used-car results are read-only pre-checks and do not replace a professional inspection.

T‑Scan Pro turns a compatible ELM327 Bluetooth Low Energy or Wi‑Fi adapter into a focused vehicle dashboard and diagnostics companion. Built around the 2019 Toyota LandCruiser Prado 150 2.8L turbo-diesel, T‑Scan Pro combines live telemetry, trip recording and Prado-specific diagnostic guidance in one clear interface. LIVE VEHICLE DASHBOARD • View speed, RPM, coolant temperature, intake temperature, boost, voltage, engine load, fuel rate and other readings when supported by the connected ECU. • Build and rearrange the dashboard around the data that matters to you. • Use the included demo simulator to explore the app without an adapter. HONEST DATA COMPATIBILITY • Supported Data Scan checks the ECU’s advertised OBD‑II capability maps. • Unsupported or unverified values are clearly shown as unavailable instead of being displayed as invented zeroes. • Diesel-specific petrol PIDs such as STFT, LTFT and conventional O2 readings are identified appropriately. PRADO DIAGNOSTICS • Organised coverage for engine and diesel emissions, DPF and exhaust, fuel and injectors, turbo and intake, transmission, 4WD, ABS/VSC and body or safety modules. • Read trouble codes, emissions readiness and available live data. • Run read-only Prado discovery to identify available modules and data safely. • Export diagnostic reports for your records or workshop. VEHICLE HEALTH • See a health score with evidence, confidence and prioritised findings. • Track maintenance items and retain historical reports. SMART ALERTS AND TRIPS • Configure coolant, boost and low-voltage warnings, including background notifications while the adapter remains connected. • Record GPS routes, trip history and live telemetry. • Export trip data and keep automatic backups in iCloud Drive. Actual readings depend on the vehicle, ECU calibration and adapter. Toyota-enhanced values such as DPF soot load, differential pressure, regeneration state, exhaust-gas temperatures and injector feedback require verified support for the connected vehicle and are never fabricated. T‑Scan Pro is a diagnostic companion and does not replace professional inspection or repair advice.
