The SimHub plugin

Your rig detected on its own, your sessions in every sim, your live grid in iRacing. Free, optional, and it sends nothing before you link it.

Download the plugin (.zip)

Version 0.9.1. Windows 10 or 11, .NET Framework 4.8. Needs SimHub(opens in a new tab) (free).

What it does

What Race Companion shows you once the plugin runs next to SimHub

  • Detects your wheel base, wheel, pedals, shifter and handbrake over USB, and matches them with the Build My Rig catalogue
  • Records each session: sim, car, track, every lap time and your consistency, the best lap's sectors, and incidents
  • Shows who is in your iRacing session and your record against them, if you turn Live Grid on
  • Sums up the telemetry of a session: speed, RPM, throttle and brake use, G-forces, fuel, tyre and brake temperatures
  • Reads your PC: processor, graphics card, memory, screens and VR headset
  • Works with every sim SimHub reads, not only iRacing

Install in four steps

Five minutes, on the PC that runs SimHub

  1. Download the plugin

    A zip with the plugin's DLL, nothing to configure.

    Download the plugin (.zip)

  2. Unblock the zip

    Windows marks a downloaded file as coming from the internet, and SimHub then refuses to load the plugin. Before extracting, right-click the zip, Properties, tick Unblock, OK.

    Or in PowerShell: Unblock-File -Path "$env:USERPROFILE\Downloads\RaceCompanion-Plugin.zip"

  3. Extract it into SimHub's folder

    Close SimHub, then extract the zip into its installation folder, usually C:\Program Files (x86)\SimHub\

  4. Start SimHub and link the plugin

    Start SimHub and enable Race Companion in Settings, Plugins. The plugin sends nothing until it is linked to your account.

    Then sign in to Race Companion on the same PC and open Data sources: the page links the plugin to your account by itself.

What it sends, and when

The short version. The whole of it is in the Privacy policy.

  • Before it is linked to your account, the plugin sends nothing: its only request asks for a pairing code, while its panel is open in SimHub.
  • Once linked, it sends your sim gear (USB IDs and names, and the gear Simucube Tuner sees behind a Link Hub; serial numbers only as a fingerprint computed on your PC), your PC's specs and a summary of each session.
  • Never the raw telemetry stream. The live grid (the drivers of your iRacing session) only if you turn Live Grid on.
  • Untick data collection in the plugin's panel in SimHub and nothing at all leaves your PC.
  • Unlink a PC from the plugin's panel or from Data sources: from then on its data is refused.
