I've been watching this project/thread with interest.

I have a comment regarding the VSS and ticks per mile. Would it be easier to find a common value, say average the value from as many common vehicles as possible and use that as a starting point? Then you could use the tank reset to create a "calculation offset value" stored for future use. If you were to verify the miles driven and the fuel total, you would know, within a close percentage, what the offsets need to be. They could be refined with each fillup.

You could provide a listing of the common offsets for a set of vehicles so that starting out, someone can set a relatively good starting offset - part of initial setup. Since it's open source, data gathering would come from those interested in expanding the project.
