Well, calling a PIC a "computer" is kind of misleading.  It is a very  
popular family of embedded processor chips, some of them very low- 
end.  A PIC powerful enough for this purpose can be had in small  
quantities for $2-3, and one would need very few additional  
components. Hardly overkill.  Of course, it is always easier to do  
what you know how to do, but objectively, if one were to start from  
scratch, in this day and age a digital solution is a no-brainer, just  
on the basis of cost. And it would also be much easier to "tweak" and  
to add features such as multiple shift patterns, performance  
reporting to a "car computer", diagnostics, etc.

An open-source project in this area would be great-fun, and I suspect  
a lot of people would chip in.  ...must resist time sink.....  :-)
