I also tested out a new lap timing system. Not sure if there are that many track day addicts here, but some of you find it useful.
Using my Nokia N95 (which runs S60 3rd Edition operating system), a Bluetooth GPS & a software download called RaceChrono. I uses the GPS to plot your times and speeds at certain points along the track. You need to first add the Start/Finish line so that it registers a complete lap, you can also add lines for sectors in different parts of the track. In comparison to a stop watch this was spot on for times, I'd be interested to see the comparo to paid for timing systems at the track.
Some screenshots:

You can see it saves all your sessions and can view the graphs later to analyse your speeds at diff points, and compare different lap times to see where your gaining or losing speed.
