Also, here is my app.ini ffb settings, copy these over yours in iRacing app.ini, see how it goes. Just save a copy of your original file first…
[Force Feedback]
allowXBoxOneOnWindows10=1 ; Set to 1 to talk to xbox one game pads on windows 10, warning the driver is buggy
alwaysRestartFX=0 ; Always restart force when updating it, set to true if wheel goes limp after a while
calibUsingRawData=0 ; Use raw joystick position over windows calibration data when detecting new joysticks
centerSpringPct=-1 ; Percent (0-100) of static centering spring force to apply, -1 is off. Not reccomended for use.
damperMode=0 ; Set damper effect type 0 = Damper 1 = Inertia 2 = Friction
damperSaturation=10000 ; Set damper saturation from 0 to 10000
dampingSliderSetsFriction=1 ; True if damping slider adjust friction effect, false to adjust wheels built in damping effect
debounceSeq_Ms=80 ; Add delay in Milliseconds to sequential shifter to reduce double shifts
disableAutoCenter=1 ; Turn auto center off on all force feedback devices
displayLinearInNm=1 ; Display the force level in peak Nm when using the linear mode
enableHotPlug=1 ; Set to 0 to turn off usb hot plugging in case you have usb disconnect issues
enableWheelDisplay=1 ; Enable the use of steering wheel displays
enableWheelDisplayBlink=1 ; Enable the display lights to blink when at the rev limit
FFBUseSimpleMinForce=0 ; 0 - Use smoothed min force, 1 - use old sharp min force
forceNoiseSuppression=0 ; Remove noisy joystick axis, even if they are calibrated by hand
forceResetBeforeStartup=1 ; Force a reset of the whole FFB system every time we create or destroy a FFB effect
initOnlyNewDevices=1 ; Set to 0 to force all devices to reinitialize when a device change is detected
invertFFBForce=0 ; Reverse the force feedback effects, if your wheel is spinning the wrong way
joyEnableVibrateAllXInputWithPedal=0 ; Vibrate all XInput devies when pedals vibrate, or just the one used to steer
joyEnableVibratePedal=0 ; Enable physics based vibrations in some pedals
joyEnableVibratePedalBinary=0 ; Use a digital on/off mode when vibrating pedals, default is to continuously change v
joyEnableVibrateThrottleWithPedal=1 ; Enables throttle vibration when brake pedals vibrate
joyEnableVibrateWheelWithPedal=1 ; Enables wheel vibration when pedals vibrate
joyEnableVibrateXInputWithPedal=1 ; Enables XInput controller vibration when pedals vibrate
joyVibratePedalMaxPct=90 ; Maximum threshold of lockup when pedal vibrates at 100%.
joyVibratePedalMinPct=10 ; Minimum threshold of lockup before pedal starts to vibrate.
reinitFanatecWheelDisplay=0 ; reinitialize the fanatec wheel display when reconnecting devices this may cause issues
resetWhenFFBLost=1 ; Attempt to reset device when force feedback interrupted by SteamVR or another application, may cause a momentary loss in steering
seperateXBox360Triggers=1 ; Set to 1 to seperate the XBox 360 joystick triggers into there own axes
steerAverageSteeringTorque=0 ; True averages 360 Hz data down to 60 Hz, false uses last sample
steeringBumpStop_Deg=45.000000 ; degrees into bump stop before max force
steeringDampingFactor=0.050000 ; Damping factor adjust down if damping becomes unstable, defautlt to 0.05
steeringDampingMaxPercent=0.000000 ; Maximum amount of damping to apply, adjust this to set damping level, values between 0.05 and 0.2 are best, overriden by damping slider
steeringDampingParkedMaxPercent=0.200000 ; Maximum amount of damping to apply when parked, adjust this to reduce wheel oscilation when parked, values between 0.05 and 0.30 are best
steeringFFBSmooth=1.000000 ; Percent of current FFB force to use vs average force, 1.0 = no average 0.001 = max average
steeringForceParkedPct=0.330000 ; Reduce FFB force by percent when parked, to help reduce oscilations
trueForceEnabled=1 ; Enable TrueForce API in Logitech TrueForce wheels
trueForceVibeEnable=1 ; Enable vibrations in Logitech TrueForce wheels
trueForceVibeGain_dB=10.000000 ; Adjust volume of true force vibration effects
trueForceVibePhysics=0 ; 1 - use physics to generate vibrations, 0 - use game audio with Logitech TrueForce wheels
