This page was inspired by Ian Hawkins, the developer of the torque application for android phones.
Based on his beta web demonstration over here, I started wondering how it was done, what and how the data was logged etc, and started creating my own version.
I then found the forums and found other people wondering how it was done and asking for the code to do their own. For this reason and that Ian apparently needs a kick “into fettling up the crude offering” I'm going to release my proof of concept work as a starting block for others which can be found here
