An OBD-II engine diagnostics tool that works with a Wi-Fi or Bluetooth ELM327 adapter.
This automotive diagnostics app displays real-time data from your vehicle's electronic control units via an ELM327 OBD-II adapter. It provides live graphing, data logging for later review, and shows and resets engine fault codes (DTCs).
You can set custom minimum/maximum limits for any sensor or PID, triggering an alert when values exceed these thresholds.
Works with both Bluetooth and Wi-Fi versions of ELM327 OBD adapters.
For best performance, use adapters version V1.5 to V2.1; later versions frequently report connectivity issues.
Important Notice:
ELM327 devices only work with OBD2-compliant vehicles:
US-market vehicles manufactured from 1996 onward,
European petrol cars from 2001, diesel models from 2003,
Japanese vehicles from approximately 2000.
In addition to standard OBD-II parameters, vehicle-specific PIDs are available for these
manufacturers:
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)
(Note: Many Mitsubishi models before ~2000 do not support OBD protocols,
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)

KWP/CAN, AT/JATCO, AMT/ZF, Vesta/Largus K4M,H4M)
GAZ - (MIKAS10.3/11.3, MIKAS11/E2)
ZAZ - (MIKAS10.3/11.3, MR140)
UAZ - (MIKAS10.3/11.3, MIKAS11/E2, M86CAN)
This list of supported models and parameters is regularly expanded.
Not all listed PIDs for a given manufacturer may be available for your specific vehicle. You can filter desired PID types in Settings > PID types.
For some models (currently certain Mitsubishi vehicles), the app enables control of auxiliary systems such as cooling fans and fuel pumps.
To read MUT parameters and control actuators on CAN-enabled Mitsubishi models (Montero/Pajero IV, Outlander 2, etc.), create a profile using the ISO 9141-2 protocol. Use ISO 15765-4 CAN (11bit 500K) or Auto for other CAN parameter profiles.
Note: Not all Mitsubishi CAN-bus vehicles support ISO 9141-2 connections.
Extensive customization options are available for creating user-defined parameters.
