Abstract
A valve () selectively shunts exhaust gas around a stage (T) of a turbocharger turbine () under control of a control system that selectively renders an EGR system () active and inactive and that develops a value for a set-point of operation for the valve. The control system comprises a first map set () containing data that the control system uses to the exclusion of data in a second map set () to develop the set-point value when the EGR system is active. When the EGR system is inactive, the control system uses the data in the second map set to the exclusion of the data in the first map set to develop the set-point value.
