What port does Forza Motorsport use for UDP telemetry?

Forza Motorsport does not have a fixed default port — you choose it in the Data Out setting. The convention in the community, and the PaceFinder default, is UDP port 5300. Any unused port above 1024 works as long as both the game and the telemetry app agree.

Why is no data arriving from Forza Data Out?

Common causes: the IP address is unreachable from the gaming machine (different subnet), the port doesn't match on both sides, a VPN is routing UDP off the local network, or the Data Out Packet Format is set to Sled instead of Car Dash. Disable VPNs, double-check the IP and port, and confirm the packet format is Car Dash.

Does Forza Data Out work on Mac and Linux?

Yes. Forza runs on Windows and Xbox, but the UDP packets it broadcasts can be received by any machine on the network — including Macs and Linux boxes running a telemetry app like PaceFinder.

What is the difference between Sled and Car Dash packet formats?

Sled is the original, older Forza Motorsport telemetry packet — a smaller fixed payload. Car Dash is the extended format used by Forza Motorsport (2023) and Forza Horizon 5, which adds lap-time, position, and dashboard fields. PaceFinder and most modern Forza telemetry tools expect Car Dash.

Setup

Forza Motorsport Data Out: How to Set Up UDP Telemetry

Enable Data Out in Forza Motorsport or Forza Horizon 5, point it at your telemetry app, and verify the stream is flowing. Takes about two minutes.

What Data Out is

Data Out is Forza Motorsport's built-in UDP telemetry feed. With one setting toggled on, the game broadcasts a packet of car data — speed, throttle, brake, tyre slip, suspension travel, lap time, and dozens of other fields — about 60 times per second to any device on your network.

Nothing is installed in-game. Nothing overlays the screen. The game simply sends UDP packets to an IP address and port you choose. A telemetry app like PaceFinder listens on that port and turns the stream into a live dashboard, lap times, and session history.

Data Out works the same way in Forza Motorsport (2023) and Forza Horizon 5. The menu paths differ slightly, but the network settings are identical.

Step 1: Find the IP address of your telemetry machine

If your game and your telemetry app are running on the same PC, you can use 127.0.0.1 (localhost). If they're on different machines on the same network, you need the local IP address of the machine running the telemetry app.

Windows

Open Command Prompt and run ipconfig. Look for the IPv4 Address under your active network adapter — typically something like 192.168.1.42.

macOS

Open Terminal and run ipconfig getifaddr en0 for Wi-Fi or ipconfig getifaddr en1 for Ethernet.

Linux

Open a terminal and run hostname -I or ip addr show.

Step 2: Pick a port

Any unused UDP port above 1024 works. The convention in the Forza community is port 5300, and that's what PaceFinder listens on by default. If you have a reason to use a different port, make sure both sides — the game's Data Out setting and your telemetry app — agree on it.

Step 3: Enable Data Out in the game

Forza Motorsport (2023)

Open the in-game menu and go to Settings → Gameplay & HUD.
Scroll down to UDP Race Telemetry and set it to On.
Set Data Out IP Address to the IP from Step 1.
Set Data Out IP Port to 5300.
Set Data Out Packet Format to Car Dash. This is the format PaceFinder and most telemetry tools expect.

Forza Horizon 5

Open Settings → HUD and Gameplay.
Scroll to Data Out and set it to On.
Enter the IP and port from Steps 1 and 2.

On consoles, the Data Out feature is in the same menu but you may need to enable network discovery for the console to send UDP packets to your local network. Most home networks allow this by default.

Step 4: Verify the stream

Start a race or get on track in free practice. Your telemetry app should immediately show data flowing — speed updating in real time, throttle and brake responding to your inputs. In PaceFinder, the listener prints a confirmation in the terminal as soon as the first packet arrives.

Troubleshooting

No data arriving

Double-check the IP. The IP must be reachable from the gaming machine. If you're on Wi-Fi but your telemetry box is on Ethernet, they need to be on the same subnet.
Check the port matches on both sides. Game and telemetry app must agree.
Disable VPNs. A VPN on either machine can route UDP traffic out of your local network and prevent delivery.
Confirm the packet format. Forza Motorsport defaults to "Sled" format. PaceFinder needs Car Dash.

Data arrives but stops mid-session

This is almost always a network issue — Wi-Fi dropouts, the gaming PC going to sleep, or a power-saving setting on the network adapter. Try running both machines on Ethernet for a session to confirm.

Firewall blocking UDP

On Windows, the first time a telemetry app listens for UDP, Windows Defender may prompt you to allow inbound traffic. Allow it on Private networks. On macOS, you may need to allow incoming connections in System Settings → Network → Firewall.

What to do next

Once Data Out is flowing, you don't need to touch this setting again. Every time you race, your telemetry app will pick up the stream automatically and start logging. From there, the work shifts to actually using the data — comparing laps, watching where you lose time, and turning the numbers into faster sessions.
