SteerRatioRate

LiveSteerRatio Application Ratio (Requires CustomSR set to 0)

  • Type: Number
  • Default: 100%
  • Range: 30% ~ 200%
  • Step: 1
  • Display unit: %
  • Menu: Driving > Steering > Steering Feel

Behavior

LiveSteerRatio Application Ratio (Requires CustomSR set to 0).

  • Higher: Increases the multiplier applied to the learned steering ratio.
  • Lower: Decreases that multiplier.

This also applies to VW MEB, including ID.4; selecting a valid manual steering ratio bypasses this multiplier. A saved rate outside the allowed range falls back to the unscaled learned ratio.

Usage

Use small, one-at-a-time changes on the same straight and gentle curve, checking delay, oscillation, and recovery after driver input.

Previously ignored ID.4 values take effect after updating. Use CustomSR=0 and SteerRatioRate=100% for the unchanged learned ratio.

Reference

[!IMPORTANT] This multiplier applies to the learned steering ratio only when CustomSR is 0.
