Here are some overlays from Saturday ... I looped it on the last run at the end of the slalom, and that&#039;s reflected on the plots.<br /><br /><img alt='' src='http://photos&#045;b.ak.fbcdn.net/hphotos&#045;ak&#045;ash1/hs436.ash1/24110_606473889506_20508129_34229528_4202866_n.jpg' /><br /><br /><img alt='' src='http://www.frameleft.com/autox/testAndTuneGPSLogs.png' />

Thanks for the update. I should have a test app available here very soon that will support the external bluetooth GPS. I&#039;ll keep you posted.<br /><br />Jeff

Trackmaster worked great on Saturday. I had to work out a couple of kinks with my GPS accuracy, but otherwise it was nice to have data from my runs.<br /><br />The only issue I ran in to was, if I started a log and then pulled up to the start line, Trackmaster would start the log prematurely, thinking that I would keep moving forward and cross split 1, even though I stopped about 8&#039; short. The remedy was simply to start Trackmaster while stopped at the start line. Once I got that down, the lap times were within 1/10 of the timing system.<br /><br />Upon reviewing my logs though, it seems that the GPS is giving up some accuracy at times. It showed my line being very different between runs in the faster sections &#040;~50 MPH&#041; when I was within 2&#039;&#045;3&#039; of my line on every run. I think this just pushed the case for external GPS support ... something faster with more accuracy would make Trackmaster an invaluable tool for grassroots motor sports.

I&#039;m pretty sure I&#039;ve got it. I&#039;ll set my check points when I walk the course. I just wish I has a 5hz GPS to log. I just ordered my bluetooth unit today, so I hope there is a solution to get it to work with Trackmaster soon.

Awesome. Let me know if you need any helping setting up Trackmaster.<br /><br />Jeff

Tomorrow is our local autocross test and tune event and my first chance to use Trackmaster for it&#039;s intended purpose. Autocross 2 weekends in a row and then a track day the next ... fun times.
