I have very few opportunities for getting files. I'm reading the i2 Seminar so I'm learning about i2 and analysis.

I have two questions,
1. How can I calculate fuel consumption?
2. Can someone send me or share with communitiy data files? I don't care about the year or the track. But I would like to have Circuit data so I can learn a little bit more. The problem is that I have data from a kart. Just temp sensor and RPM. I'm working on the example data files in i2.
Thank you for your help.
