With the current computer logic, I find the electric/gas change-over occurrs at 30 miles per hour, and I find it "tricky" to drive on electric when in town. Most people (in back of me!) want to go at least 35 miles per hour.

Has Ford issued an update to the computer system that increases the all-electric to both change-over to a higher miles per hour? Can the local service people tweek the system and make such a change?
