Calibration & Control

Pit lane speed limiter

Configure the pit-lane set speed and associated torque/dual-function switch behaviour after validating vehicle speed.

Basic setup

The pit-lane limiter controls maximum vehicle speed while the configured limiter switch is active. Set the requested pit speed and ensure the vehicle-speed input is accurate first.

Key calibration items
