This is a link to a section of road, on which I intend to perform some coastdown tests. It is nice and flat, and not very busy.
Flat coastdown run - Iowa, IA
I will probably go ahead and hook up an MPGuino to the truck, once I find a nearby RadioShack to get the necessary interfacing components. I will then record the MPGuino output using my cellphone, and upload the videos to YouTube. Once done, I will crunch the numbers from reading the videos.
