I have never used the eco map, I had AP since they came out, never knew it was there. If you want mpg, don't drive these cars.
On Cobb stage 1 I would get 25+ on the highway, pretty much what I get now at 280whp, 21psi, on my Tuningalliance.com map.
My 09 Spec B got over 26mpg on the way back from NJ last Sunday.
You can contact Mike at tuningalliance from the vendor forum below.
