MPGuino is a great Arduino/AVR based fuel trip computer that calculates mileage by directly reading fuel injector pulses and vehicle speed pulses. Great for pre-OBDII cars, and more accurate than OBDII-based trip computers.
Add support for DFRobot DFR0009 LCD Shield. Initial glancing at this module shows that the LCD I/O is pretty logically assigned, but the analog buttons leave a bit to be desired. There's a possibility that the assigned analog button pin conflicts with the VSS input signal pin.
