The Rolling Anti-lag function limits either vehicle speed or engine RPM (whichever is indicated in the settings) while the Rolling Anti-lag button is pressed, allowing turbocharged engines to build boost before a rolling launch. This is useful in applications such as roll racing where it is advantageous to build boost while maintaining a steady speed.
