1. A control method for a steering system of an automotive vehicle comprising: providing an ECU storing a plurality of steering MAPs; providing an electric motor in association with said steering system wherein a current supplied to said motor is adjusted based upon the selection of a particular steering MAP; wherein upon change from an old MAP to a new MAP, MAP blending is performed according to the following parameters: rising rate (RR) of the new MAP (RR per millisecond) equals 100%/time in milliseconds required to complete transition to the new MAP; and falling rate of the old MAP (FR per millisecond) equals [(X)/((100−Y)/RR)] wherein X is the existing blend percentage of the old MAP and Y is the existing blend percentage of the new MAP.
