Abstract:
Systems and methods for determining the lift of a wastegate valve are provided. Methods comprise determining a relation between an actuator position and a lift of a wastegate valve at engine start-up in a temperature range. The relation may be modified based on a difference between a desired boost level and an actual boost level.
