What cam and what data acq and overlay?

100% iphone and the Harrys lap timer app. Iphone 1080p camera, iphone gps, iphone accelerometer, And 20$ for the app - i couldnt be happier with it. The next things i will get are an add in gps module for better accuracy and an obd2 cable or bluetooth and with that harrys lap timer can pull in engine data (IMG:http://www.frrax.com/rrforum/style_emoticons/default/wink.gif)

I had no idea. Is this the 4s? I'm holding out for the 5 to come out.

How long can you record and how do you upload the videos? Transfer them to a computer after each race?

Yes, 4s.

I’m not sure how long it can record,, but these are 20 minute sessions and I might have had 4 sessions on there at a time?? I am having memory issues at the moment so I need to work out a solution to transfer this data while at the track.

The 2 laps I’ve shown you are the only vids that I’ve uploaded so far. I have full session vids that I haven’t figured out how to overlay with the GPS / Accelerometer data yet. For one lap at a time it is easy just select the lap in the ‘lap list’ and press ‘overlay’. It processes for a couple minutes and saves the 1 lap vid in the ‘photos’ app on the phone. From there I can post it on you tube or wherever else. But I can also watch the videos within the Harry’s lap timer app.

There are lots of other cool features like charts where you can compare your fastest lap versus other laps. Sometimes you might have a faster sector time in one lap that happens to not be your fastest lap. With that I could see that I started braking later which made me faster or I just had a faster corner speed etc. In the charts section you can overlay MPH, lateral acceleration, linear acceleration, altitude (height), and engine rpm for 2 laps at a time.

I’m still learning about it as I go so I’m sure there are many things that I’m not taking advantage of yet. The most annoying thing so far is my memory is full. On Harry’s website he recommends getting a higher memory phone and for some reason I missed that before I got my phone. I need to do some searching for a solution to this.
