Logitech (G923) Recommended Settings Guide for iRacing

If you’ve recently acquired a Logitech G923 for iRacing, your next task will be to sort out the FFB (forrce feedback). This was the main challenge I faced when reviewing the G923 in my lst post (fun little budget wheel, by the way!).

While it’s been around in the sim racing universe since, forever – the G923 introduced some unique features, particularly its TrueForce technology. This guide will help you navigate the settings to get the most out of your 2.2Nm wheel in iRacing.

Important: General Notes

Before diving into specific settings, keep these points in mind:

1. These settings are a starting point. You may need to adjust based on personal preference, car type, and track.
2. iRacing’s dynamic physics engine means optimal settings can vary between scenarios.
3. Keep your Logitech G HUB software updated for best performance.
4. Watch the “F” meter in iRacing’s FPS/Network Display box; if it frequently hits red, your force feedback might be too strong.

Logitech G HUB Settings

Start with these settings in the Logitech G HUB software:

1. Operating Range: 900 degrees
2. Sensitivity: 50
3. Centering Spring: Off (iRacing handles this)

iRacing In-Game Settings

For in-game settings in iRacing, try these:

1. Wheel Range: 900 degrees (matching G HUB)
2. Use Linear Mode: Checked
3. Reduce Force When Parked: Checked
4. Strength: Start with 8-12 (out of 20), adjust per car
5. Wheel Force: 2.5 Nm (G923’s maximum output)
6. Damping: 5-10%
7. Min Force: 0%

TrueForce Settings

The G923’s TrueForce technology offers a unique force feedback experience. To fine-tune this, you’ll need to edit the app.ini file in iRacing’s main installation folder. In the [Force Feedback] section, you’ll find these options:

1. trueForceEnabled=1 (Enable TrueForce API)
2. trueForceVibeEnable=1 (Enable vibrations)
3. trueForceVibeGain_dB=0.000000 (Adjust vibration volume)
4. trueForceVibePhysics=1 (1 uses physics for vibrations, 0 uses game audio)

Experiment with these settings to find your preferred balance of realism and comfort.

Alternative Approach

Some drivers prefer a different setup. Here’s an alternative to consider:

1. In G HUB:
   • Operating Range: 900 degrees
   • Overall Force: 100%
   • Spring Effect: 10%
   • Damper Effect: 10%
2. In iRacing:
   • Strength: 15-18 (adjust to taste)
   • Wheel Force: 2.5 Nm
   • Damping: 0%
   • Min Force: 8-12%

This setup aims for stronger overall force feedback with less damping, which some drivers find more informative.

Fine-Tuning Your Experience

Remember, these are starting points. As you get more familiar with your G923 and various iRacing cars, you might want to make adjustments:

1. If the wheel feels too heavy, reduce the Strength setting in iRacing.
2. For more detailed feedback, try increasing Min Force slightly, but be wary of introducing clipping.
3. Some cars, especially open-wheelers, might benefit from increased damping to reduce oscillation.
4. Experiment with TrueForce settings. Some drivers love the added realism, while others find it distracting.

Don’t be afraid to experiment and share your findings with the community. What works brilliantly for one driver might not suit another. The key is finding a setup that feels comfortable and provides the feedback you need for consistent, competitive driving.
