2025 Season 1 Vehicle Telemetry Update [2025.02.18.01]
2025 Season 1 Vehicle Telemetry Update [2025.02.18.01]
This is a Vehicle Telemetry Update, containing a new anonymized race data telemetry collection system.
iRacing
Anonymized Telemetry Data:
iRacing has implemented an additional, anonymized telemetry system that we will be using to power future improvements and features for the iRacing Simulation.
- This additional telemetry system is separate and distinct from the current telemetry used by Atlas, Motec and other 3rd party applications. No changes are required for 3rd parties using the existing telemetry system as it is not changing.
Race data telemetry is generated automatically while drivers are participating in select Official Series. Series with vehicle data telemetry collection enabled will be identified. After a driver exits the Session, the telemetry data they generated will be automatically, and securely, collected by iRacing.
Members may opt-out of participating in the vehicle telemetry data collection process if they wish, and telemetry data is only collected from participants with the user preference enabled who participate in specific Official Series, which will be identified.
- Members may opt-out by selecting to do so on the Settings > Preferences page.
This system will be enabled in select Official Series, beginning with a new Week 11 Series: iTested Series
- We encourage participation and entrants will be awarded the seldom-offered “iTested!” Award for participating!

2025 Season 1 Patch 2 Release Notes [2025.02.03.02]
This is a Patch Release, containing updates, improvements, and fixes for the 2025 Season 1 Release.
Simulation
Anti-Cheat - The antiquated versions of EasyAntiCheat (Kamu EAC) files have been renamed and relocated in the iRacing file structure to prevent confusion with the currently active and in use Epic Game EasyAntiCheat (EOS) version of Anti-Cheat software. - Some additional steps have been taken to remove the previous generation of the AntiCheat system used by iRacing (Kamu/EAC). - - The iRacing Updater will now ask you if you want to uninstall the old Kamu/EAC derivation of EasyAntiCheat, if you happen to still have it installed and it is associated with iRacing (Game 36). If when prompted you choose "No", it won't ask again in the future. Also note that the old Kamu/EAC installer, and our .bat script that uses it, have been moved to a subdirectory, to distinguish it as being "old" and obsolete.
Race Servers - Made a change to how the scheduler creates Open Practice Sessions.
Race Control - Fixed an issue where a Lucky Dog driver could be incorrectly forced to give up spots to lapped cars after a delayed green. We now make sure the EOL penalty isn't applied again when entering the "Two to Green" state a second time. - Consecutive single file restarts is now a value that may be overridden by the admin "!restart" command. - - The number of laps gap between cautions used by consecutive single file restarts is now admin overridable with: !csf N - - The default value is 2 laps gap. Acceptable range is 1-10 laps. Setting to 0 will revert to whatever the default setting for the session is (2). - - Consecutive single file restart behavior will not happen during green-white-checkered laps (GWC), the normal restart type will be used instead.
AI Racing - AI Drivers have improved their ability to recover from crashes or going off-course during parade laps.
Graphics - The mip map tossing algorithm has been updated. - Fixed a compatibility issue with some OpenXR runtime states. - Fixed an issue for users with 9th and 10th generation Intel CPUs running on Windows 10 who are receiving random Simulator crashes.

Super Late Model - iRacing setups have been updated.
Tracks
Circuit de Nevers Magny-Cours - Added a slowdown to prevent racers from using the pit exit to cut Turn 1.

Kevin Harvick's Kern Raceway - (Dirt Mini Oval) - Time penalties have been adjusted for racers attempting to gain time below the yellow hose.
Misano World Circuit Marco Simoncelli - (Grand Prix & Grand Prix 2007) - The slowdown penalty for straight-lining the Turn 1-2 complex through the gravel has been increased.

2025 Season 1 Patch 1 Release Notes [2025.01.08.01]
This is a Patch Release, containing updates, improvements, and fixes for the 2025 Season 1 Release.
Simulation
Anti-Cheat - Updated the "InstallEOSAntiCheat.bat" script file so that it can be correctly run using right-click > "Run as Administrator". The script will now also pause at the end so you can see its messaging.
Weather - Fixed an issue where participants joining a Session after it had been initialized could have slightly different track surface water heights in some areas of the track. Differences were minimal, but it could be noticeable when joining an event with a drying track state.
Dynamic Track Model - For the debris system, adjusted the parameters for vehicle bodies picking up debris, including better accounting for smaller body shapes, pickups being scaled by speed, and implementing a maximum amount of debris for vehicle bodies depending on chassis size. - For the debris system, improved the ability for debris to adhere and shed from vehicle bodies. - For the debris system, the algorithms for flinging debris have been updated. - For the debris system, improved the calculations for generating gravel dust by tires. - For the debris system, normalized the color for gravel dust to improve its overall tone in all environments.
Dirt Racing - For Dirt Oval Racing, apron areas should now be a bit rougher to drive on.

Audio - Support has been added to XAudio to allow single channel audio hardware, including many Bluetooth headsets. - The number of sounds that can be loaded by the Simulation has been increased. This provides greater support for third-party sound packs. - Fixed an issue where the volume selected via the user interface was not being saved to the "app.ini" file.
Pit Lane - Auto Fuel will not enable itself if a pitstop is in progress. This fixes an issue where it was briefly enabling itself and modifying fuel fill values during driver swaps in team racing.
Spotter/Crew Chief - The Italian Spotter Pack for Renzo A. Olivieri has been updated. - Fixed a grammatical error with the spotter message for having major engine power loss.
Active Reset - Fixed an error in the way detached car parts were being tracked while resetting. Hanging and detached car parts should now be restored correctly to their saved state.
Cars
BMW M2 CSR - Fixed an issue with the reflectivity of the rollbar and digital display.
Ferrari 499P - Fixed an issue where reverse wheelspin under braking was incorrectly causing electrical energy regeneration when a single wheel locks up. This fix does not lessen how punishing wheel lockups are, particularly in the wet, but does prevent the motor generator from driving the wheels in the reverse direction.
Ligier JS P320 - For the damage model, the nose hull has been stiffened slightly to prevent submarining on contact.
Porsche 718 Cayman GT4 Clubsport MR - For the damage model, adjusted the scrape damage progression thresholds for parts of the rear.
Super Formula SF23 - Honda - For the damage model, a tuning pass has been completed which fixed a pivot-point for the left sidepod hull, increased the hull dilation for the diffuser and floor to help prevent ground snags, slightly lowered floor friction, and slightly strengthened wheels.
Super Formula SF23 - Toyota - For the damage model, a tuning pass has been completed which fixed a pivot-point for the left sidepod hull, increased the hull dilation for the diffuser and floor to help prevent ground snags, slightly lowered floor friction, and slightly strengthened wheels.
