Yeah temp sensor doesn't need to be that fast. But I couldn't be bothered specifying different times for different sensors. Sorry was being lazy.
I've built a custom telemetry system for my motorcycle and it is running at 10Hz for all the sensors. It is total overkill for some of them but I have used that number because it is the sampling frequency of my GPS receiver and it dead simple to work with the raw data later. That said I'm not sampling temps, its all motion stuff. It's pretty cool because I can animate a 3d model of my bike going through the same ranges of motion that my bike went through on a particular ride.
LOL! Yeah, laziness is what also caused me to not differentiate between the sampling of coolant data (which really could be "moment to moment") and the throttle data, that originally got you "all riled up"!
Yiour bike-run recording/playback system sounds pretty neat, BTW!
