In today’s automotive landscape, understanding your car’s health and performance is becoming increasingly accessible. For car owners of 2017 models and newer, OBD2 devices equipped with WiFi offer a powerful way to tap into your vehicle’s onboard computer. These tools, when paired with the right software, can unlock a wealth of information, from real-time sensor data to diagnostic trouble codes, empowering you to be a more informed car owner.
Understanding OBD2 and the Need for WiFi
OBD2 (On-Board Diagnostics II) is a standardized system in most cars built after 1996 that provides access to vehicle data. OBD2 devices act as an interface, translating this data into a readable format for you. While Bluetooth OBD2 adapters are common, WiFi-enabled devices offer unique advantages, particularly for comprehensive diagnostics and data logging. WiFi connectivity can provide a more stable and faster data transfer rate, crucial for apps that demand real-time information and larger data streams. For 2017 and later car models, which often have more complex systems and sensors, a robust connection is paramount.
Key Features to Look for in a WiFi OBD2 Device
When selecting a WiFi OBD2 device, consider these essential features to ensure it meets your needs:
- Broad Vehicle Compatibility: Ensure the device supports the OBD2 protocols used in your 2017 or newer car. Most reputable devices offer wide compatibility across various makes and models.
- Comprehensive Data Access: Look for a device that can read a wide range of parameters (PIDs), including engine temperature, RPM, speed, fuel pressure, and more. The more data points accessible, the deeper your understanding of your car’s operation.
- User-Friendly Software Compatibility: The OBD2 device is only as good as the software it works with. Choose a device that is compatible with feature-rich and intuitive apps. Consider apps that offer customizable dashboards, data logging, fault code reading and resetting, and advanced diagnostics.
- Reliable and Secure Connection: A stable WiFi connection is vital for uninterrupted data flow. Select devices known for their reliable connectivity and data security to protect your vehicle’s network.
- Firmware Updatability: Opt for devices that offer firmware updates. This ensures compatibility with newer car models and access to the latest features and protocol updates.
Car Scanner App: Enhancing Your WiFi OBD2 Experience
To truly leverage the power of a WiFi OBD2 device, you need a capable application. Car Scanner is an excellent example of software designed to work seamlessly with these adapters, unlocking a wide array of functionalities:
- Customizable Dashboards: Car Scanner allows you to create personalized dashboards displaying the gauges and charts that are most relevant to you. Monitor real-time data points like engine load, coolant temperature, and fuel trims in a layout that suits your preferences.

-
Extended PID Support: Go beyond standard OBD2 data. Car Scanner supports custom or extended PIDs, allowing you to access information often hidden by car manufacturers. This deeper level of data can be invaluable for performance tuning or advanced diagnostics.
-
Diagnostic Trouble Code (DTC) Reading and Resetting: Like a professional scan tool, Car Scanner can read and clear DTC fault codes. It includes a comprehensive database of DTC descriptions, helping you understand the nature of any issues. The ability to read freeze-frame data (sensor readings at the time a DTC was recorded) provides further context for diagnosis.

-
Mode 06 Testing: Access ECU self-monitoring test results with Mode 06 functionality. This advanced feature can help pinpoint potential problems before they escalate, saving on repair costs and ensuring your car is running optimally.
-
Emissions Readiness Check: Quickly determine if your car is ready for emissions testing. Car Scanner can check the status of all necessary monitors, saving you time and potential re-test fees.
-
Comprehensive Sensor View: View all available sensors on a single screen for a complete overview of your car’s health. This is useful for spotting anomalies or tracking sensor behavior over time.
-
Vehicle-Specific Profiles: Car Scanner includes specialized connection profiles for various manufacturers like Toyota, Mitsubishi, GM, and many more. These profiles unlock extra features and ensure optimal communication with your car’s specific ECU.
-
Head-Up Display (HUD) Mode: Project essential driving data onto your windshield using HUD mode. This feature enhances safety by allowing you to monitor critical information without taking your eyes off the road.

-
Performance Measurement Tools: Accurately measure acceleration times (0-60 mph, 0-100 km/h, etc.) with Car Scanner’s built-in performance tools. This is ideal for enthusiasts who want to track their car’s performance.
-
Trip Computer and Fuel Consumption: Use Car Scanner as a trip computer to monitor fuel consumption statistics and other trip-related data, helping you drive more efficiently.
-
VAG Group Encoding (MQB/PQ26 Platforms): For Volkswagen, Audi, Skoda, and Seat vehicles on MQB and PQ26 platforms, Car Scanner offers encoding functions to customize hidden car parameters (feature availability varies by model).
Choosing the Right Adapter and Avoiding Pitfalls
While many OBD2 WiFi adapters are available, quality matters. For optimal performance and reliability, consider recommended brands like Kiwi 3, Viecar, V-Gate, Carista, LELink, and Veepeak. Be cautious of very cheap, unbranded adapters, especially those marked as v2.1, as they can be buggy and unreliable, potentially causing connection issues or even interfering with your car’s ECU.
Important Note: The data accessible through OBD2 devices and apps like Car Scanner depends on your vehicle’s ECU and the sensors it supports. The app can only display information that your car makes available.
Conclusion
Investing in a quality WiFi OBD2 device and utilizing a powerful app like Car Scanner is a smart move for any car owner, especially those with 2017 and newer vehicles. These tools provide invaluable insights into your car’s health, performance, and operation, empowering you to diagnose issues, optimize driving habits, and stay informed about your vehicle’s condition. By choosing the right device and software, you can unlock a new level of understanding and control over your car.
