The role of computers in a tune-up

Believe it or not, folks, auto experts now claim that there is more computer technology in most cars than exists on the space shuttle. From the time a dealership receptionist greets the consumer to completion of a vehicle service appointment, computers and programmers, like the Hypertech programmer, are an essential component in the entire repair and maintenance process. In fact, something as basic as adjusting the car's idle speed is now done by software. The mouse has replaced a wrench as the mechanic's primary tune-up tool. Using a computer terminal in contact with the manufacturer, the mechanic downloads the software into a handheld device and the information, in turn, is transferred into the vehicle. Talk about a “hands-off” approach to a tune-up.
