House of pain,
Just buy a basic lap timer and save your money for TIRES, PRACTICE and ENTRY FEES.
I've had a Mychron timer for 2 years now and it hasn't failed me yet.

Tax time works too...lol

Know what you mean; I have 2 little ones. Tax time is when I plan on getting my track bike. So getting both would be great....

As Mark said we use the G2X system on the LSTD endurance bike. I have an XT timer on the back up bike and it has never failed. BUT all the XT can do is give a lap time. Its very crude in comparison. The G2X can show EXACTLY what you do to get the lap time. Since we are endurance racing with a 3 man team we can all compare data from one rider to the next. I can share data with Curt so he can see how we get around the track and vice versa. It is a great tool to work on your riding. Especially if a rider feels that they have plateaued.

thanks for the info gabe. i run the mycron lap timer right now also, but was thinkin about gettin something like what you guys have.

i have not reached a plateau just yet, as i'm gaining about .5 second each time i'm out....but would like to have someone a bit faster than me run with it, and then i make a run, and see where i need to improve. i think it's an awesome tool...and could be worth it in the end. however, i'm wondering if it will withstand a beating when the bike hits the pavement.

Data from Monday.... the first graph is my final run session with a fast lap of 1:48 and a few 1:49's. The second graph is a speed comparison of my fast lap to CDill's when he was riding my bike.

G2x MSRH 081020 Theor

CDill's numbers are on the left, mine are on the right. Green MPH is CDill, Blue MPH is MaxGs

G2x MSRH 081020 MPH

And, finally, this is the Map Report with my fast lap data so I can correlate speeds with the map turns.

I map what you call 16 & 17 as a single turn, Turn 1. You can see it better in the final screenshot.

So does the one you have Curt show optimal lines? Do you plot out the outside and inside edge of the track and then it forms a calculated path?

You can do the inside and outside of the track. We havent done it so were not sure exactly what it offers. There is a "lap zoom" where you can compare 2 laps and it does so different lines.

I have the track with the inside and outside edges traced. It's helpful for seeing the lines, but the GPS resolution is really not good enough to use that information reliably. There is something called Differential GPS that's required for that level of accuracy. There are a couple of units made for the high end race cars with differential gps, but the cost is ten times more or worse.

While the inside and outside lines functionality is available with most GPS track mapping hardware and software, I've not yet seen one that attempts to compute optimal line. Since you don't have a means to record the variations in coefficient of friction around the track nor the positive or negative camber at all the places in the track, that functionality would be pretty difficult.
