This OBD2 engine ECU diagnostics tool utilizes a Wi-Fi/Bluetooth ELM327 adapter to provide comprehensive vehicle diagnostics. The app displays data from various electronic vehicle control units (ECUs), offering real-time graphical representations that can be saved and reviewed later. It also displays and clears Diagnostic Trouble Codes (DTCs).

Customize the app by setting minimum/maximum thresholds for each sensor/PID, triggering an alarm when these limits are exceeded. Compatible with both Bluetooth and Wi-Fi ELM327 OBD adapters (versions 1.5 to 2.1 are recommended; earlier versions may have compatibility issues).

Important Note: ELM327 chips only function with vehicles supporting the OBD2 standard:

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

This list of supported models and parameters is subject to updates. Not all PIDs listed for a specific brand may be supported by your vehicle. You can select desired PID types in "Settings / PID types."

Certain car brands (currently some Mitsubishi models) offer system control features (e.g., activating cooling fans or fuel pumps). For Mitsubishi CAN-bus models (Montero/Pajero IV, Outlander 2, etc.) requiring MUT parameter reading and actuator control, create a profile using the ISO 9141-2 protocol; other profiles (for CAN parameters) should utilize ISO 15765-4 CAN (11bit 500K) or automatic protocol selection. Note that not all Mitsubishi CAN-bus models support ISO 9141-2.

Extensive customization options are available for creating custom parameters.
