Abstract
The present invention relates to a method for controlling the performance of an engine, comprising the steps detecting an ion current in the form of a first signal analysing said first signal to determine at least one property determining a knock index based on said first signal and preferably on said at least one property combining said knock index with a plurality of factors related to properties of the engine or the operation of the engine to arrive at a engine index, and comparing said engine index with a sensitivity map of the engine to determine a correction required to improve the operation of the engine, and correcting the operation of the engine in accordance with the correction determined. The invention also relates to a system for controlling the performance of an engine.
