AeroHead,
It's nice to see you attempting this again.
There were several times when I was tempted to give up on the coast down testing with the Insight, but I have somehow stuck with it!
I use a hand-held GPS, and my readings are also "all over the place" because of the uncertainty of the unit. Especially when you start looking at delta-V and delta-Acceleration data.
I have spend literally weeks (maybe longer) working on this stuff, and "some day" will figure out how to properly process my raw data and make real-world sense out of it.
It may be possible to program a microcontroller to take Hall-effect readings from the rotating tires and store these for accurate coast down readings. Just have to figure out how to program them. Ordered a book and development kit to get started.
Keep us posted on your findings.
Jim.
