Is your car still under warranty? For a newer car like yours that may still be under warranty, you can get software updates through your Honda dealer.

Software updates are generally not developed or given to improve fuel efficiency--your car was engineered within an inch of its life to be very efficient. Updates are issues to solve problems that are discovered.
