What Can a Car Scanner OBD2 ELM Do?
A car scanner, paired with an OBD2 ELM327 adapter, unlocks a wealth of information hidden within your car’s computer. Here’s a breakdown of its capabilities:
Real-Time Data Monitoring:
- Customizable Dashboard: Design your own dashboard displaying gauges and charts for the data points that matter most to you. Monitor speed, RPM, coolant temperature, fuel consumption, and more.
- Uncover Hidden Data: Access custom (extended PIDs) to reveal information typically concealed by car manufacturers.
Diagnostics and Troubleshooting:

These profiles often unlock additional functionalities.
- Coding for VAG Group Vehicles: Access coding functions for Volkswagen, Audi, Skoda, and Seat vehicles built on the MQB and PQ26 platforms. This enables adjustments to hidden parameters within the car’s system (use with caution).
- HUD Mode: Project essential data onto your windshield for convenient viewing while driving (ensure this usage complies with local traffic laws).
