Application Description

This OBD2 engine ECU diagnostics tool utilizes a Wi-Fi/Bluetooth ELM327 adapter to access and display real-time data from various vehicle electronic control units (ECUs). The app provides graphical representations of this data, allowing for saving and later review. It also displays and clears Diagnostic Trouble Codes (DTCs) or engine fault codes.

Users can set minimum/maximum thresholds for each sensor/PID, triggering an alarm when exceeded. Both Bluetooth and Wi-Fi ELM327 OBD adapters are supported, although versions 1.5 to 2.1 are recommended due to reported issues with other versions.

Important Note: ELM327 chips are compatible only with OBD2-compliant vehicles:

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

Beyond standard OBDII parameters, the app supports specialized parameters 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 PIDs vary by brand and model. Users can select desired PID types in the "Settings / PID types" menu.

Some car brands (currently including select Mitsubishi models) offer system control features (e.g., activating cooling fans or fuel pumps). For accessing MUT parameters and controlling actuators on CAN-bus equipped Mitsubishi vehicles (Montero/Pajero IV, Outlander 2, etc.), configuring a profile with the ISO 9141-2 protocol is necessary. Other profiles should utilize ISO 15765-4 CAN (11bit 500K) or automatic protocol selection. Note that not all Mitsubishi CAN-bus models support ISO 9141-2.

The app allows for extensive custom parameter creation. The list of supported models and parameters is continuously updated.
