Can't default to ECO mode? What does ECO even do for an ecoboost?

[texasPI]

If you want eco, buy a hybrid. If you want Preformace buy a 2.0 turbo. I never considered a hybrid. Yeah I'm one of THOSE guys

Apparently, I am too. That would explain my terrible fuel economy. lol

I use ECO daily on my commute. Its 2 lane highways with mild traffic. Other than 2 small towns, I cruise at 60MPH. Engine is below 2K RPM 50% of the time. Below 2500 90%.

Hybrid would have been ideal for my use case, but the cost of waiting (in my case) was greater than the fuel savings.

Found out I can't default to ECO mode. Every time I start the engine it's in normal mode. I have to press the big button a few times to get to ECO.
A nuisance! But what does ECO even do? I can't find any difference in terms of mileage between ECO and Normal driving modes.
I guess it makes sense for the hybrid owners, where in ECo mode the battery can be more efficiently used.
But for an ecoboost, I can't think of anything that may help. Maybe a higher gear when cruising? Wonder how much gas that will save.

Such an annoying feature. How can it be, in 2023, that a setting can’t just STAY in the last selected mode??

I haven’t used any other modes but normal in my 2.0 and I average about 8-8.5L/100km
Better than EPA

OK, who has one of those around northern Illinois that wants to share the cost?

If you share the cost, only one of you is getting the physical module, LOL.

It is installed in the fuse box and pushes the button for you.
