I can't think of a car that could use an 8-bit value for VSS/mile.
One thing i did with contrast, is built-in the brightness setting into it. I.e, take the LSB 2 bits of Contrast to determine which brightness index to use. So 44 would be brightness[0], 45 is [1], 46 is [2], 47 is [3], 48 is [0]. I found that I was never ever changing the brightness, so I re-assigned the middle button to other things, and just make it dim-out a couple minutes after engine-off.
I would like to see how you cleaned up the timers & buttons. I like what you did in the Inj ISRs, by directly grabbing TCNT2 and overflow_count instead of calling microseconds().
I only recently discovered that recursive microseconds bug & got rid of it after i couldn't understand why it should ever do that. I still have an older bug that's hanging my 'guino up, right near the time when the timer2 value rolls over past 0xFFFF FFFF. Unfortunately, it takes 5-7 days for the bug to trigger, so I'm still waiting to catch it.
