MAIRA (Marvin’s Awesome iRacing App) is a high-performance companion for sim racers who want more immersion, more insight, and more control—without the usual spaghetti of plugins and workarounds. Built from the ground up using real-time iRacing telemetry, MAIRA drives advanced features like highly tunable force-feedback, pedal haptics, and wind simulation that react instantly to what the car is actually doing. Every subsystem is engineered for precision, low latency, and stability, turning raw data into something you can feel, see, and trust. In short: MAIRA doesn’t just show you the race—it helps your rig experience it… preferably at hurricane levels of awesome.

Donations are completely optional. I will never charge any fees for using MAIRA. That said, donations make me warm and fuzzy and is a great motivator for me to keep working on MAIRA. A huge thank you to everybody who have donated already! ❤️

Version 2.1.7776

This Version

  • Name the nodes in your custom graphs! Thanks to Alan Le for this feature!
    • Give any node a name of your own, such as "Road feel" or "Curb rumble", using the pencil next to its name in the node settings.
    • The built-in graphs now name the nodes whose purpose isn’t obvious from their type, such as "Parked centering" and "Road and tire detail".
    • Node names show up in the tuning profiles list, and importing a graph update now brings its node names and descriptions along.
  • Tuning profiles are now kept separate for each game in the game bridge.
    • A car or track that exists in both iRacing and another game (like the Ferrari 499P in Le Mans Ultimate) now gets its own profile in each game.
    • The first time you drive a car in another game, its profile starts as a copy of the iRacing one with the same name, so your existing tuning carries over.
  • Updated SimHub properties: the settings you pin in your FFB graph are now available in SimHub. Thanks to Alan Le for this update!
    • The old racingWheelAlgorithm and steering effects properties have been replaced by the new racingWheelGraph properties, so SimHub dashboards that used them will need updating.
    • Includes the matching updated SimHub plugin.
  • Pedal haptics now send commands only when an effect changes (plus a refresh at least once a second), which should stop Simagic P1000 pedals from occasionally dropping off USB. Thanks to Mike-Last!
  • Fixed the FFB graph selector showing the wrong graph name after switching to a car with its own saved graph.
  • Fixed car profiles losing their saved maximum values when loaded (for example, understeer 14/45 turning into 14/14). This also affected oversteer, seat of pants, pedal frequency, and auto target.
  • MAIRA now reconnects to SimHub automatically instead of disabling SimHub telemetry until restart when an older SimHub plugin is still running.
  • Updated translations.

Recent Updates

Highlights from the past two weeks, in case you skipped a few versions.

  • New Accessibility page with a steering remap for drivers with limited arm movement!
  • New Graph overlay! The graph moved from its own page into an overlay window you can show while driving.
  • Force feedback now re-opens automatically when you unplug and replug your wheel.
  • Fixed force feedback stutters when another USB device was plugged in or removed while driving.

Become a MAIRA expert. The Documentation is where you’ll find everything you need to get up to speed fast—step-by-step guides, clear tutorials, and a no-nonsense FAQ that answers the questions you will have five minutes before a race. Whether you’re doing a first install, fine-tuning advanced features, or troubleshooting something that feels one click away from gremlins, this is your racing manual. No fluff, no mystery—just practical help to keep MAIRA running smooth, fast, and race-ready.

Feel the speed for real. The MAIRA Typhoon Wind Sim converts simulator telemetry into powerful, real-time airflow, creating a physical sensation of speed that screens, force feedback, and bass shakers alone can’t provide. Its compact dual-fan design mounts directly beside your wheelbase for strong, immersive airflow without the tubes, ducts, and clutter found in traditional wind simulators. Fully assembled and ready to use, Typhoon gets you from box to track in minutes with support for iRacing through MAIRA and additional racing and flight simulators through SimHub.

Feel the forces for real. The MAIRA Seat Belt Tensioner is all about turning acceleration telemetry into body-load sensation. This DIY belt feedback system blends surge, sway, and heave into independent left and right shoulder tension, tightening and relaxing the belts to mirror braking, acceleration, cornering, and vertical impacts. Unlike motion rigs that shine with quick jolts, the SBT can hold sustained belt pressure, giving you a clearer feel for ongoing load and making the car easier to read without needing a full motion rig. Built with off-the-shelf components, 3D-printed parts, and clear step-by-step assembly guidance, it’s designed to be builder-friendly, easy to mount, and seriously immersive once you’re strapped in. This also works for all games supported by SimHub – not just iRacing.

This section is where the helmet comes off and the story begins. Learn about Marvin—the sim racer, tinkerer, and slightly obsessive engineer behind MAIRA—and how years of racing, game development, and “there has to be a better way” moments turned into the app you’re using today. Here you’ll find background on the ideas that shaped MAIRA, a look inside Marvin’s personal sim rig and hardware choices, and the philosophy that drives every feature. It’s part origin story, part rig tour, and part friendly reminder that MAIRA was built by a sim racer, for sim racers.

This is where the community takes the wheel. The Media section brings together videos from sim racers, creators, and reviewers around the world who have spent time with MAIRA and shared their experiences. From deep-dive tutorials and force-feedback breakdowns to first impressions and long-term usage stories, this is the place to see how MAIRA performs outside the lab and out on the virtual track. If you’re curious how other drivers use it, tune it, or push it to its limits, this is the highlight reel — real voices, real rigs, and real opinions, all in one place.
