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).

Configurable minimum/maximum thresholds for each sensor/PID trigger alerts. The app supports both Bluetooth and Wi-Fi ELM327 OBD adapters, though versions 1.5 to 2.1 are recommended due to reported issues with other versions.

Important Note: ELM327 chips are compatible only with OBD2-compliant vehicles:

• USA: 1996 and later
• Europe: 2001 and later (gasoline), 2003 and later (diesel)
• Japan: Approximately 2000 and later

Note: Not all listed PIDs for each 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 (cooling fan, fuel pump, etc.). For MUT parameter reading and actuator control on CAN-bus Mitsubishi vehicles (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.
