CarBit

A diagnostic tool for engine ECUs using a Wi-Fi or Bluetooth ELM327 OBDII adapter.

This car diagnostics app lets you read data from various electronic control units via an ELM327 OBDII adapter. You can view real-time graphs, save them for later review, and read or reset engine fault codes (DTCs).

You can set min/max thresholds for any sensor or PID to trigger an alarm notification.

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

For best results, use adapters version V1.5 or similar. There are frequent reports of issues with V2.1 adapters.

Important Notice:

ELM327 adapters only work with OBD2-compliant vehicles:

US market cars from 1996 onward,

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

Japanese market cars from approximately 2000.

In addition to standard OBDII parameters, specialized parameters are supported for various car brands. Currently available options include:

This list of models and parameters is regularly updated.

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

For certain car brands (currently some Mitsubishi models), you can control various systems like activating 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 using the ISO 9141-2 protocol. Use ISO 15765-4 CAN (11bit 500K) or "Auto" in other profiles for reading CAN parameters.

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

You also have extensive options for creating custom parameters.
