Just a comment on some of the BSFC maps above...
Given the island for lowest consumption ranges down as far as 1 500 RPM in some examples (Saturn 1.9 for instance) it seems to make more sense to aim for the lower end rather than the exact centre.

In other words revving at a constant 1750 RPM or so should give the same BSFC spot as 2500 but with lower friction from using fewer revs.

Just an observation.
