It would certainly be interesting, but it's bound to be primitive, 
although not as primitive as the ones intrinsic to carbs. Bosch was 
limited to the analog computer technology of the time, so the mapping 
had to be simple. With today's logic, it's possible to program in n 
dimensions with impunity.

The really interesting question would be whether an "ideal" profile 
exists for our engines. In my mind, "ideal" would mean max power when 
you asked for it, up to the point where things started to get too 
hot, but max economy (and min emissions) otherwise.
