This OBD2 engine diagnostics tool utilizes a Wi-Fi/Bluetooth ELM327 adapter to access and display real-time data from various electronic vehicle control units (ECUs). Key features include graphical data representation, data logging for later review, and the ability to read and clear Diagnostic Trouble Codes (DTCs). Configurable min/max thresholds trigger alerts for critical sensor values.

Compatibility:

The app supports both Bluetooth and Wi-Fi ELM327 OBD adapters. Version 1.5 to 2.1 adapters are recommended; older versions may exhibit compatibility issues. ELM327 chips function only with OBD2-compliant vehicles:

• USA: 1996 and later
• Europe: 2001 and later (gasoline), 2003 and later (diesel)
• Japan: Approximately 2000 and later

Extended Vehicle Support:

Beyond standard OBDII parameters, the app offers extended support for numerous car brands, including (but not limited to): BMW, BYD, Chery, Chrysler/Dodge, Citroen, Daewoo, Fiat, Ford, Geely, GM/Chevrolet/Pontiac, GreatWall, Honda, Jeep, KIA, Hyundai, Land Rover, Lifan, Mazda, Mercedes, Mitsubishi, Nissan, Opel, Peugeot, Renault, Skoda, SsangYong, Subaru, Suzuki, Toyota, VAG, Volvo, VAZ, GAZ, ZAZ, and UAZ. Specific supported parameters vary by brand and model. A "Settings / PID types" menu allows users to select desired parameters.

Advanced Features (Specific Brands):

Some car brands (e.g., certain Mitsubishi models) allow for system control (e.g., activating cooling fans or fuel pumps). Accessing MUT parameters and controlling actuators on CAN-bus equipped Mitsubishi vehicles (Montero/Pajero IV, Outlander 2, etc.) requires configuring a profile with the ISO 9141-2 protocol. Note that not all Mitsubishi CAN-bus models support ISO 9141-2. Custom parameter creation is also possible.

Version 3.5.9 (September 30, 2024):

This latest version includes minor bug fixes and improvements. Update to the newest version for optimal performance.
