CarBit

An OBD2 engine ECU diagnostic tool that works with Wi-Fi and Bluetooth ELM327 adapters.

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

You can set minimum and maximum values for each sensor or PID. When these limits are exceeded, an alarm will trigger.

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

For best performance, use adapters from V1.5 up to V2.1. Models beyond V2.1 often receive complaints about unstable operation.

Important Note:

ELM327 chips only work with OBD2-compliant vehicles:

US market cars manufactured from 1996 onward,

European gasoline cars from 2001, diesel cars from 2003,

Japanese vehicles from approximately 2000.

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

car brands. 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 per model (ATF Temperature,

Knock detection, etc.)

Land Rover - (RANGE/3.6L, DISC4/3.0L, DISC3/TD6, FL2/TD4)

Lifan - (MT20U, MT20U2, ActecoME797, ME1788, ABS)

Mercedes - (W203/CDI, W169/CVT, W168)

Mitsubishi - (CAN/ECU, CAN/CVT, CAN/SS4II, CAN/AWC, MUT/OBD, MUT/GDI)

(Reminder: Mitsubishi models before roughly 2000 (around 50/50 for 2000) do not support OBD, so they

are incompatible with ELM327)

Nissan - (CAN/ECU, CAN/CVT, CAN/AWD, CAN/METER, CONSULT2)

Opel - (ECU, AT, ABS, X18XE, Z16XE, Y17DT, CDTI1.6L, CDTI1.3L)

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

The list of supported models and parameters is regularly updated...

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

For select car brands (currently some Mitsubishi models), you can also control various systems—such as activating the cooling fan or fuel pump.

To read MUT parameters and control actuators on certain Mitsubishi models with CAN bus (e.g., Montero/Pajero IV, Outlander 2), create a profile using the ISO 9141-2 protocol. Keep other profiles (for reading CAN parameters) on ISO 15765-4 CAN (11bit 500K) or Auto.

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

You also have extensive options to create custom parameters.
