CarBit

An OBD 2 engine ECU diagnostics tool that uses a Wi-Fi/Bluetooth ELM327 adapter

The application for car diagnostics enables you to access data from various electronic vehicle systems using the ELM327 OBDII adapter. It provides real-time graphical displays and the ability to save and review these graphics later. Additionally, it displays and resets engine fault codes and DTC trouble codes.

You can set customizable minimum and maximum values for each sensor/PID, triggering an "alarm" when these thresholds are met.

The app supports both Bluetooth ELM327 and Wi-Fi ELM327 OBD adapters. For optimal performance, it is recommended to use adapters version 1.5, as there have been numerous complaints about the incorrect operation of version 2.1 adapters.

Important Notice!

ELM327 chips are compatible only with vehicles that support OBD2:

• Cars manufactured in the USA since 1996
• In European countries since 2001 for gasoline cars and since 2003 for diesel cars
• In Japan, since approximately 2000

In addition to standard OBDII parameters, the app supports special parameters for various car brands. The current options include:

• BMW - (DIESEL, E91+AT)
• BYD - (MT20U, ABS)
• Chery - (MT20U, MT20U2, ActecoME797)
• Chrysler/Dodge - (DIESEL, AT)
• 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)
• Geely - (MT20U, MT20U2, M797)
• GM/Chevrolet/Pontiac - (ECU, AT, ABS, SiriusD42)
• GreatWall - (MT20U2, EOBD, CAN/4D20)
• Honda - (Fit, Accord, CRV/DIESEL, Insight)
• Jeep - (ECU, DIESEL, AT, TPMS)
• KIA, Hyundai - ~15 PIDs for each model (ATF Temperature, Knock detected, etc.)
• Land Rover - (RANGE/3.6L, DISC4/3.0L, DISC3/TD6, FL2/TD4)
• Lifan - (MT20U, MT20U2, ActecoME797, ME1788, ABS)
• Mazda - (ECU, AT, ABS, CAN/TPMS, CAN/SWA)
• Mercedes - (W203/CDI, W169/CVT, W168)
• Mitsubishi - (CAN/ECU, CAN/CVT, CAN/SS4II, CAN/AWC, MUT/OBD, MUT/GDI)
  • Note: Mitsubishi vehicles manufactured before ~2000 (up to 2000, it's 50/50) do not support OBD and thus cannot work with ELM327.
• Nissan - (CAN/ECU, CAN/CVT, CAN/AWD, CAN/METER, CONSULT2)
• Opel - (ECU, AT, ABS, X18XE, Z16XE, Y17DT, CDTI1.6L, CDTI1.3L)
• Peugeot - (MEV17.4.2, EDC16C3, ME744, AL4/CAN, AL4/KWP)
• Renault - (CAN/ECU, CAN/DIESEL, KWP/DIESEL, Sagem2000, KWP/EMS3132)
• Skoda - (CAN UDS TSI/TFSI)

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

The list of models and parameters is continually being updated...

Not all PIDs listed for a particular car brand may be supported by your vehicle. For convenience, you can select the types of required PIDs in the "Settings / PID types" section.

For certain car brands (currently some Mitsubishi models), the app offers the ability to control various systems, such as turning on the cooling fan or gasoline pump.

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

Note that not all Mitsubishi CAN-bus models support ISO 9141-2 connectivity.

The app offers extensive options for creating your own parameters.
