Control method and control system for internal combustion engine with turbocharger

The present invention provides engine control capable of receiving an indication of the pedal position, and pre-processing the indication of the pedal position to determine whether the received indication of the pedal position corresponds to the antisurge mode activation condition (31). In response to the received indication of the pedal position corresponding to the antisurge mode activation condition, the boost pressure and the engine speed are used to look up the static control parameter lookup table to select a control parameter indicating an air flow requirement (32). The selected control parameter is sent to the ECU (60) so as to control the engine using the air flow requirement indicated by said control parameter.
