Hey tz1:

I'm having this problem, too. However, I dig this project and want to help out.

I was taking a look at the source code and your use of Python and plain old C is exactly the same approach I would take. I have been writing stuff for myself using BoaConstructor for years. I've also written stuff for the old OnHand watch computer in C. I have yet to combine the two in a single program but the approach has obvious advantages so I'd like to learn how.

If you would like some help, can you tell me about your development environment? I'd like to match yours on my side.

I can also offer a web page on my site and I'd like to help with documentation.

Oh, my motivation:
I'm an avid motorcyclist, too. I have an '07 Yamaha R1 that I take to the racetrack for trackdays. I've been using a standalone GPS logger (GT-31) to help me improve my riding but the refresh rate is too slow and the position accuracy too poor to be as helpful as it could be. I bought the N810 and a G-Rays-I to improve the refresh rate to 10Hz and position accuracy to 2.6 m right out of the can. Just a few tweaks and additional configuation options turns miniGPSD into exactly what I'm looking for.

Your development direction into OBD, maps and especially the kinematics stuff would turn the N810 into a full fledged data acquisition system and that would be really great. If I can help, I'd be pleased to.
