iRacing Season 2 Update 2 Build Released

iRacing has released the Season 2 Update 2 for their online racing simulation, adding a string of fixes and improvements to the iRacing platform.

Compared to last month’s update that added the LMP1 race cars as well as the brand new Indycar, the new release is relatively humble, containing no new content but rather focusing on fixes and improvements.


Dynamic Track

  • The area of influence for aerodynamics picking up track dust has been widened, but less dust gathered in this way will be returned to the track than previously.
  • Updated the method used to calculate the water content below the track surface to better account for the influence of built-up dirt on top of the prepared surface. The result is that water is lost more readily as cars disturb the built-up dirt.

Hybrid Power Units

  • Hybrid deployment schemes now update end-of-straight speeds to reflect how quickly your car is going. In addition, the system is now capable of marking end-of-straights even when the brakes aren’t applied, which was an issue for turn 1 at Phillip Island, with the MP4-30 in particular.

Paint Shop

  • Leo Bodnar and Simsteering logos have been updated.


  • Fixed an issue where the helmet and visors for the drivers of some vehicles were disappearing at close viewing distances or angles. The vehicles affected include:
    – – Chevrolet Monte Carlo SS
    – – Ford Mustang FR500S
    – – Kia Optima
    – – Lotus 79
    – – Mazda MX-5 Cup circa 2015

Video Capture

  • The latest version of the D3DGear API has been added. This fixes a conflict with Oculus Rift headsets.


A new switch has been added to the “app.ini” file in the [Force Feedback] section:

  • – – calibUsingRawData=0 1 = Use the older raw parameters to detect input during calibration.
    – – – This may help in the rare case that a wheel is installed with a bad driver and the device can not be detected.


  • A new switch has been added to the “app.ini” file in the [Misc] section:
    – – irsdkAutoLogDisk=0 1 = Force disk-based telemetry logging set to “ON” every time you enter your car. (WARNING: Setting this is bound to fill up your hard drive, make sure you have lots of room (Telemetry can eat a few hundred megabytes per hour)!)

Dallara IR18

  • Oval tire wear rate has been reduced slightly and altered oval tire compound very slightly.
