Tip: Axis mapping varies by device. If pedals appear swapped, check your wheel's driver software to customize axis assignments.

Steering Wheel Tester

The ultimate online tool for testing racing wheels, pedals, shifters, and handbrakes. Visualize wheel rotation and pedal response in real-time.

Wheel Rotation

See your wheel turn in real-time. Test the full rotation range from 180° to 1080° depending on your hardware.

Pedal Calibration

Test throttle, brake, and clutch pedals. Verify full travel range and check for potentiometer issues.

Linearity Check

Detect dirty potentiometers and sensor issues. A clean pedal should produce a smooth, linear response curve.

Frequently Asked Questions

Common questions about testing racing wheels online

Q Why does my wheel only show partial rotation?

The browser receives normalized axis values (-1 to +1). Some wheels need driver software to set the rotation range (e.g., Logitech G HUB, Thrustmaster Control Panel).

Q My pedals show jumpy/erratic values?

This usually indicates dirty or worn potentiometers. Clean them with electrical contact cleaner, or consider upgrading to hall-effect or load cell sensors.

Q Can I test force feedback here?

Browser APIs don't support force feedback output. Use this tool for input testing only. For FFB testing, check your wheel's manufacturer software.

Q Which axis is which pedal?

Axis mapping varies by device. Common mappings: Axis 0 = Steering, Axis 1 = Throttle, Axis 2 = Brake, Axis 3 = Clutch. Use this tool to identify your specific layout.
