An OBD2 engine ECU diagnostic tool that uses a Wi-Fi/Bluetooth ELM327 adapter.

This automotive diagnostic app lets you display data from various vehicle electronic control units using an ELM327 OBDII adapter. View real-time graphics, save them for later review, and read or reset engine fault codes (DTCs).

You can set min/max thresholds for each sensor/PID, triggering an alarm when values exceed these limits.

Compatible with both Bluetooth ELM327 and Wi-Fi ELM327 OBD adapters.

For best performance, use adapter versions V1.5 to V2.1. Later versions often receive complaints about unstable operation.

Important Note:

ELM327 chips only work with OBD2-compliant vehicles:

US-market cars manufactured from 1996 onward,

European vehicles from 2001 (gasoline) and 2003 (diesel),

Japanese cars from approximately 2000.

The model and parameter list receives regular updates...

Not all PIDs listed for a specific brand may be supported by your vehicle. You can filter required PID types in "Settings / PID types" for convenience.

For certain brands (currently select Mitsubishi models), you can control various systems (activate cooling fan, fuel pump, etc.)

To read MUT parameters and control actuators on Mitsubishi CAN-bus models (Montero/Pajero IV, Outlander 2, etc.), create a profile with ISO 9141-2 protocol while keeping other profiles (for CAN parameter reading) set to ISO 15765-4 CAN (11bit 500K) or Auto.

Note: Not all Mitsubishi CAN-bus models support ISO 9141-2 connectivity.

Extensive customization options are available for creating your own parameters.
