Ah, understand. The empeg, gps synched should do the job nicely.

Now, perhaps you would be interested in an empeg accelerometer? This one is way on the back burner but I have built prototype hardware. In theory this could give 0-60, 1/4 mile, peak HP, g-force type info. No idea how accurate it will be in practice and the math will take some work.

Cheers,
