Ah, I see. My apologies for the misunderstanding. To my warped way of
thinking, it's not a throttle position sensor unless it actually senses
throttle position, otherwise it's just an optical encoder for whatever it's
connected to.
And I probably still don't understand your comments about A/F meter
accuracy. Best power is somewhere around .85 while best fuel economy is
somewhere around 1.1-1.2. Since my definition of "best performance"
includes both of those points, I see no utility in a gauge that won't read
either one accurately. But it's certainly true that a proper wide-band
sensor costs less than a new carb.
BTW, stoichiometric (Lambda = 1.0) is no longer necessarily 14.7:1. Pretty
much all of the US is now running 'oxygenated' fuel, which requires more
fuel to reach stoich. E10 for example takes around 14.0:1. And while we
are exploring this road, it might be entertaining to design a setup that
would burn E85 successfully, which reaches stoich somewhere around 9.7:1.

My goals are more lofty; I want best power at any rpm when I step on the
loud pedal, combined with minimum fuel consumption (best economy) while
cruising. And for me, 'cruising' includes anything from drifting along at
2300 rpm (~ 55 mph) to holding a constant 4200 or so (~100 mph).
