Stream Dock telemetry dashboard plugin for Forza Horizon Data Out.
ApexDash is an unofficial Stream Dock telemetry dashboard plugin for Forza Horizon Data Out.
It turns a Stream Dock / Mirabox / AJAZZ device into a racing telemetry dashboard with readable live tiles for speed, RPM, gear, boost, tires, grip, inputs, session stats, and connection status.
ApexDash is an unofficial plugin.
It is not affiliated with Microsoft, Turn 10 Studios, Playground Games, or the Forza franchise.
ApexDash receives live telemetry from Forza Horizon through the built-in Data Out UDP feature and displays selected values on Stream Dock buttons.
The goal is to provide a clean, data-only telemetry dashboard without hotkeys, SimHub relay requirements, or unnecessary background activity.
Current core features:
- Live Forza telemetry over UDP Data Out
- Ready-to-use telemetry tiles
- Configurable metric tiles
- Gauge-style tiles for percentage-based values
- Shift light support
- Tire and grip monitoring
- Input monitoring
- Session statistics
- Telemetry connection status
- Lazy runtime behavior
- Built-in debug endpoint for troubleshooting
ApexDash currently includes the following tile types:
- Speed
- RPM
- Gear
- Boost
- Universal Metric Tile
- Gauge Tile
- Shift Light
- Tire Monitor
- Grip Coach
- Input Monitor
- Session Stats
- Telemetry Status
The Universal Metric Tile can be configured to show different telemetry values depending on the selected metric.
Gauge Tile is designed for RPM, fuel, throttle, brake, and other percentage-style telemetry values.
ApexDash is designed as a data-only plugin.
It does not provide:
- hotkeys
- SimHub relay functionality
- external overlay rendering
- game memory reading
- game process injection
The UDP listener starts only when ApexDash tiles are visible or active on the current Stream Dock page.
When no ApexDash tile is visible, the plugin should release the UDP port after a short delay.
- Windows 10 or Windows 11
- Stream Dock software
2.10.179.426or newer - Forza Horizon with Data Out enabled
- Stream Dock device supported by the Stream Dock app
Supported device families may include Stream Dock, Mirabox, and AJAZZ devices, depending on compatibility with the Stream Dock software.
-
Close Stream Dock completely, including the tray icon.
-
Extract the release ZIP.
-
Copy this folder:
com.nineerza.apexdash.sdPlugin
to:
%APPDATA%\HotSpot\StreamDock\plugins
-
Start Stream Dock again.
-
Look for this category:
ApexDash
-
Drag ApexDash actions onto your Stream Dock buttons.
You can also run:
install_apexdash.batfrom the extracted ZIP folder.
In Forza, enable Data Out and use the following settings:
Data Out: On
Data Out IP Address: 127.0.0.1
Data Out IP Port: 23666ApexDash listens on:
127.0.0.1:23666 UDPFor telemetry to update correctly, the game must be actively sending Data Out packets.
In most cases, this means you need to be driving in-game rather than sitting in a menu or pause screen.
ApexDash includes a local debug endpoint for troubleshooting.
The debug endpoint is active only when at least one ApexDash tile is visible or active on your Stream Dock page.
After Stream Dock starts and an ApexDash tile is visible, open:
http://127.0.0.1:28766/stateUseful fields:
udpBound: true
connected: true
packetRate: 60 / 120 / 140 etc.
lastPacketAgeMs: should update while telemetry is activeSelf-test endpoint:
http://127.0.0.1:28766/simulateIf /simulate updates the tiles but Forza does not, the plugin is working and the issue is usually related to Forza Data Out IP/port configuration.
Check the following:
- Forza Data Out is enabled.
- Forza Data Out IP is set to
127.0.0.1. - Forza Data Out port is set to
23666. - You are actively driving in-game.
- You are not sitting in the menu or pause screen.
- No old version of the plugin is still installed.
- Stream Dock was fully restarted after installing or replacing the plugin.
Only one process can listen on UDP port 23666.
Run in PowerShell:
Get-NetUDPEndpoint -LocalPort 23666 | Select-Object LocalAddress, LocalPort, OwningProcessThen check the owning process:
Get-Process -Id <PID> | Select-Object Id, ProcessName, PathWhen an ApexDash tile is visible, the process should be Stream Dock's node20.exe running ApexDash.
When no ApexDash tile is visible, ApexDash should release the UDP port after a few seconds.
Remove old plugin folders such as:
com.erza.forzadash.sdPlugin
com.nineerza.apexdash.sdPlugin_oldfrom:
%APPDATA%\HotSpot\StreamDock\pluginsAfter removing old folders, restart Stream Dock completely.
ApexDash depends on Forza Horizon Data Out.
If the game is not sending telemetry packets, ApexDash cannot display live values.
ApexDash does not read game memory, inject code, or modify the game. It only listens for UDP telemetry packets sent by the game through its Data Out feature.
- ApexDash requires the Stream Dock software to run.
- The plugin works only while Stream Dock is active.
- Telemetry depends on Forza Data Out being correctly configured.
- Only one application can listen on UDP port
23666at the same time. - Device compatibility depends on Stream Dock software support.
- Some telemetry values may depend on the specific Forza Horizon title and Data Out packet behavior.
- Stream Dock plugin format
- JavaScript / Node runtime used by Stream Dock
- UDP telemetry listener
- Forza Horizon Data Out
- Local debug HTTP endpoint
