Connector not detecting LMU?

Follow this procedure:

  1. Close LMU and the connector
  2. Download the two files below:
  3. Place rFactor2SharedMemoryMapPlugin64.dll in:
    \SteamLibrary\steamapps\common\Le Mans Ultimate\Plugins\
  4. Place CustomPluginVariables.JSON in:
    \SteamLibrary\steamapps\common\Le Mans Ultimate\UserData\player\
  5. Start the connector
  6. Start LMU

✅ Once connected, LMU should show "Waiting for track"
✅ Once connected, LMU should show the track and car names
This means the connector is now connected.

Still no telemetry? Install SimHub

If the connector detects LMU but not the car or track ("waiting"), the game no longer loads the telemetry plugin. SimHub reinstalls and enables it:

  1. Install SimHub (free, button below).
  2. Open SimHub → Games tab → choose Le Mans Ultimate and accept the plugin installation it offers.
  3. Restart LMU, then the MSR connector: car and track are detected.

This fixed the issue for several drivers after the latest LMU update.
