Try the Virtual Race Car Engineer. This interactive program steps the user through the major areas of race car setup and tuning, asking simple questions about the telemetry readings and behavior of the car under specific race conditions. "How is the car reacting at initial turn-in?" "How does the car feel from mid-corner to corner-exit when on the throttle?" "What type of track are you preparing for?"
