Tame harsh Direct Drive oscillation without losing tire grip detail. Dial in calibrated Slew Rates (Nm/ms), dynamic damping, and wheel inertia for Simucube 2, Fanatec Podium DD, Moza R12/R16, and Simagic Alpha.
❓ Frequently Asked Questions (Sim Racing Telemetry)
What is Slew Rate on a Direct Drive steering wheel?
Slew rate measures how quickly the servo motor can deliver torque changes, expressed in Newton-meters per millisecond (Nm/ms). If slew rate is too high (e.g. 9.0+ Nm/ms), hitting a curb or sausage barrier can violently whip the wheel out of your hands. Setting it to 4.0 - 5.0 Nm/ms preserves critical tire grip sensations while smoothing dangerous spikes.
Why does my Direct Drive wheel oscillate back and forth when driving in a straight line?
Oscillation happens when there is insufficient mechanical damping to resist the motor's own inertia. Adding 8% to 14% Natural Damping and 5% Friction instantly eliminates the violent wobble and keeps the wheel centered on straightaways.
