🚀 Features

Record Telemetry

• This app allows users to save all telemetry to a CSV file for later analysis
• All incoming telemetry data is saved (along with the timestamp)

This gif was created by using the Recording feature and Forza Map Visualization to make a 3D trace of the player's XYZ coordinates during a race

Map Trail

• Your car's path will be drawn in real-time as you drive around in either Motorsport or Horizon

Fuel Management

• Displays the number of laps you can go until you run out of fuel
• Displays the amount of fuel consumed per lap
• Displays your car's MPG

Lap Dashboard

• Displays time and split time for every lap, not just your best and previous lap

Runs on your Local Machine

❓ FAQ

Why does the MPG value look off?

Because Forza doesn't tell us how much fuel is actually in the car, so a best guess is made. The MPG calculation is assuming that every car in Forza has around 14 gallons of fuel. Fixing this (or getting the correct fuel capacity values) is on my to-do list.

Why is the app running slowly?

Most likely the map has too much data to render.

Why do some things look out of place?

This app looks best when it's in a 1920x1080 window (and looks even better in fullscreen mode). When the window deviates from this size, some visual elements might be placed incorrectly. Press F11 to make the app fullscreen.

Can I use this app with an Xbox?

Yes! You have to change the IP address and port in the Forza settings menu to match your computer's IP and port.

🆘 Troubleshooting

The app appears but I can't see any data

This probably means that you don't have the right version of the C# SDK installed, or you downloaded the SDK but did not install it. Run dotnet --info in any terminal and make sure you have .NET SDK v6.0 installed.
