Device
Steering Device
Pick which DirectInput force-feedback wheel MAIRA should control. If you don’t see your wheel here, your wheel might not be turned on, or it may not be a DirectInput FFB device (or the driver isn’t exposing it correctly).
Power
Turns MAIRA force feedback on/off.
The power button can be different colors. Here is the meaning of those –
- Red = Emergency shut-off is active
- Cyan = Waiting for the iRacing simulator telemetry data stream
- Yellow = Force feedback is not active (reason shown below steering device)
- Green = All systems go, force feedback is active!
You can map this button to an input on your button box, to act as a safety / emergency switch to turn the wheel FFB off.
Test
Plays a short test signal through the wheel. Useful to verify MAIRA is actually driving the wheel.
Reset
Forces MAIRA to reinitialize the wheel device. Useful if the wheel “goes dead” or feels desynced.
Overall Strength
These settings define your overall torque scaling.
Wheel Force
Your wheel’s physical maximum torque (Nm).
Set this to your wheel’s rated peak torque (example: 10 Nm, 15 Nm, 25 Nm, etc). MAIRA uses this to keep units consistent and to compute other values correctly.
Here is a handy table of Wheel Force Settings.
Strength
Overall strength multiplier (0–100% normally).
This is the “how strong should it feel” knob. This remaps the iRacing car steering wheel torque into a smaller value that will fit on your wheelbase without clipping.
For example, the Mazda MX-5 Cup car tends to produce approximately 20 Nm peak force on the steering wheel. If you only have a 10 Nm wheelbase, this is too much! So, for this situation you would set Strength to 50% to make the 20 Nm force fit on your 10 Nm wheelbase without clipping (50% of 20 Nm = 10 Nm).
Here is a table showing a few examples of recommended Strength settings for various cars and wheelbases –
| Wheelbase | Car | Strength |
| Logitech G29 (2.2Nm) | Mazda MX-5 Cup (20 Nm) | 11% |
| Simagic Alpha Evo Pro (18 Nm) | Mazda MX-5 Cup (20 Nm) | 90% |
| Fanatec ClubSport DD (12 Nm) | Dallara IR18 (60 Nm) | 20% |
| Simagic Alpha Evo Ultra (28 Nm) | Dallara IR18 (60 Nm) | 47% |
If you enable Allow Super Strength, this can go up to 200% (see SWITCHES).
Max Force
This is the “target peak torque” MAIRA uses internally for normalization. It’s tightly linked to the two settings above.
Important: MAIRA keeps these three values in sync:
MaxForce = WheelForce / Strength- Changing Wheel Force or Strength will update Max Force automatically.
- Changing Max Force will update Strength automatically.
iRacing’s native FFB also has a “Max Force” setting in their UI, which works exactly like how it works in MAIRA. You can copy and paste iRacing’s Max Force setting if you want the FFB strength to feel the same.
Here’s another handy table –
| NASCAR Cup Series (Next Gen) | ~28-35 Nm |
| IndyCar (IR-18) | ~30-60 Nm |
| Mazda MX-5 Cup | ~18-22 Nm |
| Supercars (V8) | ~22-28 Nm |
| GT3 (Ferrari, Porsche, BMW, etc.) | ~8-14 Nm |
| GT4 | ~12-18 Nm |
| GTP / LMDh | ~10-16 Nm |
| Formula 3 | ~14-20 Nm |
| Formula Vee | ~16-22 Nm |
| Street Stock | ~18-25 Nm |
Auto Margin
Adds a safety margin to Auto Max Force.
Example: if Auto Max Force finds 40 Nm and Auto Margin is 10%, the suggested value becomes 44 Nm.
Use negative values to allow more clipping (useful for weaker wheels).
Set
Sets Max Force to the current suggested max force (Auto Max Force) value.
Clear
Clears the suggested max force so MAIRA can “re-learn” from fresh driving.
Current Force
Shows the strongest raw torque MAIRA has observed, based on live steering torque while on-track.
Auto Max Force
How it works (in plain English):
MAIRA watches your live steering torque while you’re on-track and shows the suggested max force as “Auto Max Force”. The suggested max force also takes into account the Auto Margin. If you want to use the suggested max force, press the “Set” button to update the Max Force setting.
Algorithm
This section controls how MAIRA processes iRacing’s steering torque signal before sending it to your wheel.
Algorithm
Available algorithms:
- Native 60Hz: Uses iRacing’s 60 Hz torque signal (simplest).
- Native 360Hz: Uses iRacing’s higher-rate steering torque samples (more detail).
- Detail Booster: Boost details for more road feeling
- Delta Limiter: Cuts down on details for a smoother feeling
- Detail Booster On 60Hz: Same as detail booster, but with lower latency
- Delta Limiter On 60Hz: Same as delta limiter, but with lower latency
- Slew and Total Compression
- Multi Adjustment Toolkit
Default: Detail Booster On 60Hz
Soft Clipping
Applies a soft limiter near the extremes so the signal eases into ±100% instead of “brick wall” clipping.
Default: ON
Prediction Mode
Predicts the next steering-torque sample to reduce latency and improve responsiveness.
- Disabled
- Predict K1 (predicts 1 frame ahead)
- Predict K2 (predicts 2 frames ahead)
Default: Predict K1
Prediction Blend
How much predicted torque is blended in:
- 0% = no prediction effect
- 100% = full prediction
Default: 35%
Detail Boost
Boosts rapid torque changes to increase “texture” and small details.
Default: 50%
Detail Boost Bias
How quickly the boosted signal is pulled back toward the base signal. Higher bias = less “ringing” / less exaggerated detail.
Default: 10%
Delta Limit
Limits how fast torque is allowed to change per step. Helps reduce harsh spikes and oscillation, and makes the driving feel smoother.
Default: 500 Nm/s
Delta Limiter Bias
Bias toward the raw signal. Higher bias = follows the raw torque more closely.
Default: 20%
Slew Threshold
Threshold at which slew compression starts clamping fast torque changes.
Default: 0.02% of Max Force
Slew Compression Rate
How strongly fast changes are compressed once above the threshold.
Default: 65%
Total Threshold
Threshold where total compression starts acting on the overall signal.
Default: 65% of Max Force
Total Compression Rate
How much the overall signal is compressed beyond the Total Threshold.
Default: 75%
Torque Compression
Compresses high-torque peaks to reduce clipping and keep more usable midrange.
Default: OFF
Slew Rate Reduction
Reduces how quickly torque can drop (and in some cases rise), smoothing sharp transitions.
Default: OFF
Detail Gain
Boosts deviations from the “steady” component of the signal to enhance road detail.
Default: OFF
Output Smoothing
Adds smoothing to the final output to reduce chatter / jitter.
Default: OFF
Output
The output settings are recommended only for people with gear driven or belt driven wheels. Direct drive wheel users should leave all output settings OFF.
Minimum
Forces a minimum output magnitude.
Useful if your wheel has a deadzone where small forces aren’t felt.
Default: OFF (0%)
Maximum
Hard cap on output magnitude (below 100%).
Useful if you want to keep the strongest hits under control without changing your overall scaling.
Default: OFF (100%)
Curve
Applies a response curve:
- Positive values emphasize larger forces (more dramatic build-up)
- Negative values emphasize smaller forces (more “alive” near center)
Default: OFF (Linear)
Preview
Live Preview Graph
Shows how the current Algorithm transforms input torque into output torque using a recorded sample set.
- The RED line is the 360 Hz input signal from iRacing.
- The CYAN line is the output of the selected algorithm.
Where the red and cyan lines overlap, the line becomes white in color.
Recording selector
Choose which saved recording is used for preview.
Record button
Starts a new recording (only enabled while on-track). This gives you a sample set you can use to preview algorithm changes consistently.
Tip: Hover the preview graph to get a zoomed view.
Wheel LFE
You will need to download and install a utility called VB-CABLE for the Wheel LFE feature to work. More information on that can be found here – VB-CABLE Setup
LFE Recording Device
Select which audio capture device MAIRA listens to for LFE magnitude.
Strength
How much LFE magnitude is added directly to wheel torque.
This is intended for subtle texture or low-frequency effects, not for replacing normal steering torque.
Default: 5%
Crash Protection
Crash Protection reduces wheel force temporarily when a crash-like event is detected.
Longitudinal G-Force
Threshold for longitudinal G (braking / impacts) to trigger Crash Protection.
Default: 8.0g
Lateral G-Force
Threshold for lateral G (side impacts) to trigger Crash Protection.
Default: 6.0g
Duration
How long Crash Protection remains active (seconds), plus a short recovery ramp.
Default: 1.0 sec
Force Reduction
How much force is reduced when Crash Protection triggers.
Default: 95%
Curb Protection
Curb Protection reduces algorithm aggressiveness temporarily when shock velocity spikes (curbs, bumps).
Shock Velocity
Threshold for suspension shock velocity to trigger Curb Protection.
Default: 0.50 m/s
Duration
How long protection stays active.
Default: 0.10 sec
Force Reduction
How strongly the algorithm is “softened” while protection is active.
Default: 75%
Parked Effects
These apply when moving very slowly (roughly 0–5 mph), to keep the wheel calmer / more manageable in pits and when stopped.
Force Feedback Strength
Scales down overall forces as speed approaches zero.
Default: 10%
Parked Friction
Adds velocity-based friction when parked (helps stop the wheel from feeling loose at a standstill).
Default: OFF
Other Features
Soft Lock Strength
Adds a soft force barrier near your steering angle limit to simulate a “bump stop”.
Default: 25%
Racing Friction
Adds velocity-based friction while driving (reduced automatically as you approach parked speed).
Default: OFF
Wheel Centering Strength
Adds a centering force toward wheel center (optionally enabled separately for racing vs parked; see SWITCHES).
Default: 75%
Effects
Gear Change Vibrate Strength
Adds a short vibration pulse on gear shifts. Setting this to 0% turns the effect off.
Default: 10%
ABS Vibrate Strength
Adds a vibration pattern while ABS is active. Setting this to 0% turns the effect off.
Default: 10%
Private Messages
These control MAIRA sending private chat messages to the driver (useful confirmations and event notifications).
Send private chat messages to the driver
Master enable for all MAIRA private messages.
Default: ON
Enable input mapped setting update messages
When enabled, MAIRA can send confirmation messages when certain settings are changed via button mappings.
Default: ON
Enable crash protection messages
Sends a message when Crash Protection triggers.
Default: OFF
Enable curb protection messages
Sends a message when Curb Protection triggers.
Default: OFF
Switches

Enables MAIRA centering force while driving.
Default: OFF
Center wheel while parked
Enables MAIRA centering force while stopped / crawling.
Default: ON
Fade force feedback when entering or exiting car
Smooth fade-in/out of steering torque as iRacing transitions on/off track.
Default: ON
Enable Logitech RPM lights
Uses Logitech’s LED SDK to drive RPM LEDs (when available).
Default: ON
Allow up to 200% strength (potentially dangerous)
Allows Strength to go above 100% (up to 200%).
Use with caution: this can produce very high forces depending on your Wheel Force and Max Force.
Default: OFF
Enable FFB even if iRacing simulator FFB is on
Normally MAIRA suspends itself when iRacing FFB is enabled (to prevent fighting signals).
Default: OFF
Enable this only if you know what you’re doing (and ideally keep iRacing FFB off).
