I there any DIY laptop chip emulator/data logger out there?

Well the bluetooth module still has to go through USB. And USB communication is pretty robust, with very low bit error rate (something like 1 x 10^-10).

I wouldn't worry about using a bluetooth module.

USB is not the weak link - knowing the dropout rates of bluetooth, the idea of that signal with all that critical data being transmitted wirelessly does not instill confidence - why wouldn't you just plug the thing into the computer? it's not like it could be more than 3 feet away anyway for tuning

i've spent about 200 hours tuning a kit this year, and the part throttle stuff is hard enough to repeat consistently without adding bluetooth error rates and drop outs to the equation - that just sounds like a bad idea to me, and no advantage that i can see to it

Even if bluetooth is the weak link - the signal still has to go through the USB error detection. So if there is a bluetooth dropout or bad bit, the USB should detect it and request the packet to be resent...

Eh - different strokes for different folks.

In 2 words: wireless connectivity. There are wires all over the place in my house, and I am trying to prevent that from also being the case in my car.

But now that I failed to obtain a module from motes, I'll have to use one of my own. The ones I have conform to the bluetooth 2.0 spec, and I would think that the pinout (V,D-,D+,G), which is standard USB, would match the header side of the ostrich that has the 4 pins in a row. Can anyone confirm this?
