ALGORITHM TO REMEDIATE LOST LIFETIME FUEL ECONOMY CACHED DATA UPON HARDWARE SWAP

A method is provided for determining a vehicle lifetime fuel economy using a remote server. The method includes retrieving from at least one vehicle control module vehicle data including an amount of total fuel used by the vehicle, determining whether the total fuel used by the vehicle is greater than or equal to a stored fuel used value, calculating an adjusted total fuel used if the total fuel used is not greater than or equal to the stored fuel used value, and calculating the lifetime fuel economy based on the adjusted total fuel used.
