Abstract
Various methods for compensating variation in the geometry and position of linkages and valve seats in wastegate assemblies are provided. In one example, a method of operating a wastegate in an internal combustion engine comprises, at engine startup, placing a wastegate valve at a seat, recording a position of the seat and associating the seat position with one or more operating parameters, and modifying a position of a wastegate actuator based on the seat position throughout engine operation.
