The 4x20 lcd seems to be working without modification to the code (same pinout as 2x16 too):
I really would like to get started on one of these, even though I have a Scangauge and have a car that runs OBDII.
Do you think it's possible to program a Freeduino, along with an Elm 327 decoding IC, to work with OBDII? What about adding more EEPROM? Is that possible to allow for more code? Just giving ideas for MPGuino 2.0 (3.0?). I think it would be more aesthetically pleasing when using the 20 x 4 to add a space between the readouts and go out another decimal place, just a thought. By the way, this is an awesome project, you are an asset to us Ecomodders.
