I don't understand why folks who don't like Eco mode make statements like "there is NO GAIN in using Eco mode to climb hills." That may be true in mild weather, but when the heater is sucking power big time in Winter, or the A/C less so in Hot Summer weather,there is indeed a point in using Eco, because it reduces the power used by the HVAC, and that matters, especially on slow climbs. Please just add that caveat, and I'll stop doing it myself...
