The free version

  • allows you to test the connectivity to the ELM-based OBD interface and your vehicle
  • communicates with your car and shows diagnostic information but contains also some limitations in shown data
  • can be unlocked to a full version with a valid licence key

In addition to the software, you need separate ELM327-based OBD-II adapter to connect to your vehicle! See the OBD2 Adapters page for more information and some compatible adapters.
