I wrote a software application for my Windows Pocket PC Phone (HP hw6955 if anyone cares) for tracking and managing my fuel economy and vehicle maintenance.

I was thinking about making it available as freeware if anyone was interested in using it as well. Currently it's targeted at Windows Mobile 5/6 devices, but I think it should work on Mobile 2003 devices too.

It is able to work in US, Metric, or Imperial interchangeably and does some basic fuel economy stats including City / Hiway and temperature data. It is also able to record vehicle maintenance costs and calculate an operating cost per mile or km. It also has a reminder system for scheduled maintenance like oil changes and stuff.

Anyway, if anyone is interested just post a reply. If I get enough interest it will motivate me to write up some documentation and do a bit more final testing then post it sometime in the next few weeks.

Two climate control systems, one inside and the other at the tailpipe.
