Hi,
I'm going to head out soon and do some Cd coast down tests! I'll be recording video on my Fuji point and shoot, so the data gathering will be fairly painless -- I've got it attached to a mini tripod, which I will then tape to my steering wheel, so that it videos the ScanGauge II. I've set it to kilometers...
Questions: I've downloaded the
spreadsheet from the
Instructables page
How do I get reasonably accurate air density? (I'll check the elevation of my test site in Google Earth!)
How do I get the best guesstimate for tire rolling resistance?
