To utilize cloud tuning, simply launch a cloud-designated profile from the Sim Commander main screen. A cloud-designated profile will have the cloud icon in the top-right.
When you get on track with a cloud designated profile, Sim Commander will announce that it has modified your profile for the game, car and track you are in. A full match is best, indication that we have full data for the game/car/track. A partial match is also possible, indicating that we have good data for the vehicle, but not at the track you are on. A no match status indicated that we've collected insufficient data for the game/car/track you are using in the last 5 years. This is rare and usually on occurs for brand new vehicles and tracks.
If you don't have any cloud-designated profiles, please follow this tutorial, which will help you to auto-discover any games you have installed and automatically create default profiles for them: https://www.simxperience.com/slides/slide/how-to-auto-discover-games-profiles-47?search_category=44
