CarBit

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 control units (ECUs), offering real-time graphical representations that can be saved and reviewed later. It also displays and resets engine fault codes (DTCs).

Users can configure minimum/maximum thresholds for each sensor/PID, triggering an alarm when these limits are exceeded. The app supports both Bluetooth and Wi-Fi ELM327 OBD adapters, with versions 1.5 to 2.1 recommended (older versions may have compatibility issues).

Important Note: ELM327 chips are compatible only with OBD2-compliant vehicles. Generally, this includes vehicles manufactured in the USA since 1996, in Europe since 2001 (gasoline) and 2003 (diesel), and in Japan since approximately 2000.

Note: Not all listed PIDs for a given brand are guaranteed to be supported by every vehicle. Users can select desired PID types in "Settings / PID types". Some Mitsubishi models offer system control features (cooling fan, fuel pump, etc.). For MUT parameter reading and actuator control on certain CAN-bus Mitsubishi models (Montero/Pajero IV, Outlander 2, etc.), an ISO 9141-2 profile is required. Not all Mitsubishi CAN-bus models support ISO 9141-2.

Custom parameter creation is also possible.
