Dude, I like the idea. If I could code, I'd try and help. So I'll just try and encourage.

If I could make a few suggestions though..

A built in tach (code it like the speedo, run a 5th wire?)
US/Metric cominations (for those of us that find Liters per 100km confusing, maybe just a code option (easily switchable))
And a (what is now) Current MPG Histograph. I saw somebody that modded theirs to do it, and it looked niiice.

The stock screen works, and there really isn't an easy way to get them hooked up on every-single car, so there's no getting around that.

I hope you're able to help push the mpguino onwards. It's a great idea, and a great concept, but I feel that there are still some bugs that need to be sqished with it, and they should try and use the 328 or maybe even the 1026 or 2056 for even moar upgradeablility.
