Connecting your iPhone to your car’s onboard diagnostics (OBD) system opens a world of information about your vehicle’s performance, health, and potential issues. But with so many OBD2 apps available on the App Store, finding the best car diagnostic tool for iOS can be challenging. This review explores Car Scanner ELM OBD2, a popular option offering a comprehensive suite of features.
Car Scanner ELM OBD2: A Deep Dive into Features
Car Scanner ELM OBD2 distinguishes itself with a robust set of features designed to provide in-depth vehicle diagnostics and performance monitoring. Here’s a closer look:
Customizable Dashboard and Data Insights
The app allows you to create personalized dashboards displaying real-time gauges and charts for the data points that matter most to you. This customization extends to adding custom (extended PIDs) to access information typically hidden by manufacturers. Car Scanner can display and reset Diagnostic Trouble Codes (DTCs) like a professional scan tool, leveraging a vast database of DTC descriptions to help you understand the issue.
Advanced Diagnostics and Emission Readiness
Going beyond basic code reading, Car Scanner ELM OBD2 allows access to Mode 06 data, providing valuable insights into ECU self-monitoring test results. This feature aids in proactive maintenance and can help reduce repair costs. The app also checks your car’s emission test readiness, ensuring you’re prepared for inspection. Conveniently, you can monitor all sensors on a single screen for a comprehensive overview of your vehicle’s status.
Compatibility and Unique Connection Profiles
Car Scanner supports any vehicle complying with the OBD2 standard (most vehicles manufactured after 2000, potentially extending back to 1996). The app boasts numerous connection profiles optimized for various makes and models, including Toyota, Mitsubishi, GM, Opel, Vauxhall, Chevrolet, Nissan, Infiniti, Renault, Dacia, Hyundai, Kia, Mazda, Volkswagen, Audi, Skoda, Seat, BMW, and more. These profiles unlock specific features tailored to each manufacturer.
Performance Monitoring and Trip Computer Functionality
Beyond diagnostics, Car Scanner ELM OBD2 offers performance monitoring tools, including accurate acceleration measurements (0-60, 0-100, etc.). It also functions as a trip computer, tracking and displaying fuel consumption statistics.
Additional Features for VAG Group Vehicles
For vehicles within the VAG group (Volkswagen, Audi, Skoda, Seat) built on the MQB and PQ26 platforms, the app offers encoding functionality, enabling access and modification of hidden car parameters. A unique feature is the HUD mode, projecting data onto your windshield for easy viewing while driving.
Hardware Requirements and Adapter Recommendations
Car Scanner ELM OBD2 requires a Wi-Fi or Bluetooth 4.0 (Bluetooth LE) compatible OBD2 ELM327 adapter to connect to your vehicle. Recommended adapter brands include Kiwi 3, Viecar, V-Gate, Carista, LELink, and Veepeak. Avoid cheap, generic ELM327 adapters, particularly those marked as v2.1, as they often have connectivity issues and can negatively impact vehicle performance.
