4)Sweet. I've got pre-ODBI so I need to figure out how to hook up sensors to IOIO. The 0-3.3V is going to be an issue.
5) Yeah I didn't see the link on the site either. Maybe make the tab Red or bold or something.

The scaling will be off from what the sensor would read if it were fed 5v, but that doesn't really matter in our custom application.
IOIO supplies regulated 3.3v on the board, so you can use that to feed the sensor and map your sensor output to whatever value you want to measure (tire temp, water temp, oil pressure, etc.)
Sensor value Scaling (2.12v=85psi) and Labeling (PSI instead of volts) doesn't seem to be implemented in WifiLapper yet. When that is implemented we can worry about scaling to 3.3v instead of 5v. You just will have to do it manually instead of using the published specs.
