BlackRack Overlay

BlackRack Overlay is a free, independent telemetry overlay application for Le Mans Ultimate, focused on multiclass endurance racing, clear information while driving and low renderer overhead. SimHub is not required.

It reads LMU's official shared memory on Windows and uses optional local LMU and RaceControl data only to enrich fields such as weather, strategy and DR/SR. If an optional service is unavailable, the overlays keep running.

Main overlays included

• Standings — configurable multiclass order, gaps, intervals, lap data, tyres, Virtual Energy, pit state, flags, penalties and optional DR/SR.
• Relative — nearby traffic with class position, intervals, tyres, lap data and driver information.
• Delta — live comparison against overall, session, stint or last-lap references, with persistent records.
• Compact Timing — current/last/best lap times, three-sector feedback and recent laps.
• Fuel / Virtual Energy — endurance strategy, consumption, autonomy, pit demand and achievable saving references.
• Trailing + Pedal — live inputs and driving traces.
• Lift & Coast — the official five-lamp energy-saving cue, with optional active-only visibility.
• Damage + Tyres — compact tyre, brake and damage status.
• Detailed Damage — expanded vehicle and corner damage information.
• Pit-stop Estimate — LMU's official service total and repair breakdown.
• Stint history — recent stint laps, resource use, tyres, pace and consistency.
• Dashboard — compact gear, shift lights and configurable car readouts.
• Track Map — learned circuit path with live multiclass vehicle positions.
• Flags — yellow, blue and checkered flag notifications.
• Safe Rejoin — approaching-car and pit-exit warnings.
• Weather Forecast — upcoming conditions using LMU's official weather icons.
• Current Conditions — temperatures, wind, humidity, rain, grip and track state.

Make it your own

Enable only the overlays you need and position them around your driving view. Each panel can be resized and configured independently, including text size and transparency.

Create named profiles and assign them to:

• Game, spectator or team mode.
• Practice, qualifying and race sessions.

The interface is available in English and Spanish. Smooth, Balanced and Efficiency performance profiles let you choose the right balance between update cadence and system load.

Requirements

• Windows 10 or Windows 11, 64-bit.
• Le Mans Ultimate installed through Steam.
• LMU's official shared-memory plugin.
• Microsoft WebView2 Runtime.

SimHub is not required. The installer includes the WebView2 bootstrapper. You do not need to copy any BlackRack DLL into the game folder.
