Problem is that 3 tenths separate 10 drivers at the DE Cup. Check our DE Cup Grand Prix results at Sebring and Daytona

Ya, I know - I was thinking more in terms of my own performance, not timing or racing against others, and for that I was pleasantly surprised for a $14 iphone app. I will get a more sophisticated device in the near future, but this is holding me over for now.

Just buy the Harry's Lap Timer...it's not a waste of money. It works like it says. You will probably want to get the Tom Tom cradel for it too.

in conjunction with the Emprum Ultimate GPS signal booster, as recommended by Harry.

Haha ok I'm gonna do that

Why people with $150k+ track day cars cannot afford a decent data acquisition system always lets me wondering.
Because we're cheap, so we can afford new $150K cars..... stop wondering!

Seriously, Harry's is pretty good- optimistic maybe.

I certainly didn't blow $150K on my track car. Harry's is great but don't bother bringing your iPhone to Thunderhill without a dish on your roof to find a signal....just useless.

Do you have signal booster like i referred to above? Never been to thunderhill, but at my local tracks it has usually worked well. A couple times i could not get a good signal when there was heavy cloud cover.
