Diag my car OBD2/ELM
Turn your phone into a car scanner: live OBD-II data, fault codes & fuel log.
About Diag my car OBD2/ELM
DiagMyCar — your pocket car diagnostic station
Connect a cheap ELM327 Bluetooth adapter to your car's OBD-II port and turn your Android phone into a full-featured
diagnostic tool. Read live engine data, scan and clear fault codes, track fuel costs, and keep an eye on your car's
health — all in a fast, clean interface.
🔌 Works with standard OBD-II / ELM327 adapters
Compatible with almost every petrol and diesel car sold since 2001 (EU) / 1996 (US). Just pair a Bluetooth ELM327
adapter and connect — the app auto-detects your car's protocol and the sensors it supports.
📊 Live sensor monitoring
Watch real-time data from 150+ parameters: RPM, speed, coolant temperature, engine load, throttle position, intake
air, MAF, MAP, fuel trims, O₂ sensors, timing advance, battery voltage and many more. Smooth scrolling charts,
configurable gauges, and per-parameter warning thresholds.
⚠️ Fault code scanner (DTC)
Read stored, pending and permanent trouble codes with plain-language descriptions from a built-in database of
thousands of codes. Clear codes (turn off the check-engine light), view freeze-frame data, check readiness monitors,
and keep a history of every scan.
⛽ Fuel & cost tracking
- Live fuel consumption calculated from your engine's airflow.
- Manual Fuel Log: record each fill-up (date, volume, cost, odometer) and get automatic statistics — consumption per
fill, price per unit, cost per 100 km/mi, total spent, distance covered — with trend charts. A built-in calendar makes
logging quick, and a summary card can show your numbers right on the dashboard.
🏎 Performance & trips
Measure 0–100 km/h acceleration, track top speed and peak RPM, and record full trips with distance, average speed,
idle time and fuel used.
❤️ Engine health & smart alerts
Get an A–F health grade from a composite of key sensor readings. Statistical anomaly detection learns your car's
normal behaviour and warns you when something drifts out of range. Optional sound and vibration alerts for red-zone
values, plus custom speed and RPM limit notifications.
🚗 Car Mode (HUD)
A clean, full-screen heads-up display of your most important readings — perfect for a phone mount while driving.
🧰 Built for enthusiasts

- Customizable dashboard with gauges and numeric tiles.
- Custom monitor tabs — group the parameters you care about.
