Wow talking of total bunkum......where did you pluck that from....
On a steady cruise the best FE is at the lowest road speed without ending up going rich (due to EMS fueling strategy in whatever car your driving), so sme cars you have to speed up a little on grades to keep it from going rich, best FE at rpm of somewhere near best torque ..... where is the logic for that? That would be at about 7000rpm in a Honda S2K!
As for tuning to idle economically, very difficult, and most manufacturers only tune it to idle economically when stationary, most jack the idel whe moving, and on manual cars retard the ignition to add a torque reserve in case the clutch suddenly comes up!
