So Bueller turn me on to a GPS lap timer he downloaded through his phone App store. I think he has a Droid or something because I couldnt find the same App that he had. I did search on my IPhone App store and found a GPS Lap timer that learns the track as you ride it so there is no searching and downloading the track map to make it work. It works pretty fricken good. The only thing I dont like, or havent got used to is that it doesnt give you a start/finish time. Once it has learned the track, (it takes about a lap and half), it displays your real time pace, i.e. your running a 1min 10 second pace in the case of IMI, rather than duration of the lap starting at 0:00. Once you stop you can then review each lap time, mph, braking/neutral/acceleration points, fastest lap and highest mph. Im sure it does more but Im still tryin to figure it out.
The app is called "Lapping Coach Lap Timer" Its a $30 app which seems like a lot until you figure a new lap timer and beacon runs almost $300.
Hope this is of use to someone.
