Using F1SpeedF1Speed is a telemetry application intended to run side-by-side with F1 2011 (and F1 2010) to display realtime data for instant feedback on setup changes and changes to driving style, such as braking points, throttle on points and apexes. It's useful also to analyse the effect of KERS usage at difference points of the track and can easily highlight where you're the weaker during your lap.
