I don't think so, map is a good indicator of load.
FYI, the general rule of thumb I use in an unknown car is 2/3 throttle and center the shifts at about 2200 rpm. You can probably narrow it down with more observation.
Also wanted to make sure you were aware of "advanced" driving techniques from there i.e. pulse and glide, engine kill switch for glide, basic hypermiling techniques like avoiding the brakes, paying a lot more attention to potential obstructions so you can time them, etc. etc. I was getting about 55mpg around town with my saturn, and accelerating at 2/3 throttle and gliding to stops was virtually undetectable as far as traffic flow (with a 4mph bump start if it is just a stopsign or leave it off for longer stops).
P&G is a pita at higher speeds though, need aerodynamics (which would compliment your gearing change). But around town it is quite natural and puts the hybrids to shame.
BTW, never heard of an 89 corsica with a 3.1. 3.1 is going to be a little big for best economy, especially on the hiway with the throttle closed (manifold vacuum=pumping losses), but it's what you got. P&G works because you only operate the engine with the throttle well open, and off the rest of the time (idling is %100 loss). A smaller engine will have a more open throttle at cruise.
