An engine diagnostics tool for OBD2 ECUs that connects via a Wi-Fi or Bluetooth ELM327 adapter.

This car diagnostics app lets you view data from various vehicle electronic control units using an ELM327 OBDII adapter, display real‑time graphs, and save or review them later. It also shows and resets engine fault codes (DTCs).

You can set a minimum and maximum value for each sensor or PID, and an alarm will trigger when these thresholds are reached.

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

For best performance, use adapters from version V1.5 to V2.1; later versions have reported issues.

Important Note:

ELM327 chips only work with OBD2‑supported vehicles:

US cars manufactured from 1996 onward,

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

and Japanese cars from around 2000.

Beyond standard OBDII parameters, specialized parameters are available for various

car brands. Currently supported options include:

BMW – (DIESEL, E91+AT)

UAZ – (MIKAS10.3/11.3, MIKAS11/E2, M86CAN)

The list of models and parameters will be updated regularly.

Note that not all PIDs listed for a particular car brand may be supported by your vehicle. You can filter the required PID types in "Settings / PID types".

For certain car brands (currently some Mitsubishi models), you can control various systems such as the cooling fan or fuel pump.

To read MUT parameters and control actuators on Mitsubishi models with a CAN bus (e.g., Montero/Pajero IV, Outlander 2), create a profile with the ISO 9141‑2 protocol, and keep the ISO 15765-4 CAN (11bit 500K) or automatic protocol in other profiles for reading CAN parameters.

Not all Mitsubishi CAN‑bus models support ISO 9141‑2 connectivity.

The app also offers extensive options for creating custom parameters.
