An engine diagnostics tool using an ELM327 Wi-Fi/Bluetooth adapter for OBD2-compliant vehicles.

This car diagnostics app displays data from various vehicle electronic control units via an ELM327 OBDII adapter. It shows real-time graphs, saves them for later review, and reads and clears engine fault codes (DTCs).

You can set minimum and maximum values for each sensor/PID to trigger an alarm when exceeded.

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

For best performance, use adapters from version V1.5 to V2.1. Many users report issues with other versions.

Important Notice:

ELM327 chips only work with OBD2-supported vehicles:

US vehicles manufactured from 1996 onwards,

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

Japanese vehicles from approximately 2000.

In addition to standard OBDII parameters, specialized parameters are available for various

car brands. Currently supported options include:

BMW - (DIESEL, E91+AT)

BYD - (MT20U, ABS)

Chery - (MT20U, MT20U2, ActecoME797)

Citroen - (C4, C5, Sagem2000, CAN/AT6, EDC16C3, MEV17.4.2)

Daewoo - (SiriusD42)

Fiat - (IAW49F, IAW5SF)

Ford - (ECU, PWM/AT, PWM/ABS, CAN/DIESEL, CAN/AT, CAN/TPMS, CAN/ABS)

Knock detection, etc.)

(Note: Mitsubishi models before approximately 2000 (50/50 for 2000) do not support OBD, so they cannot

work with ELM327)

The list of models and parameters is regularly updated.

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

For certain car brands (currently some Mitsubishi models), you can control various systems (e.g., 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 the ISO 9141-2 protocol. In other profiles (for reading CAN parameters), keep the protocol as ISO 15765-4 CAN (11bit 500K) or Auto.

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

Extensive options are available for creating custom parameters.
