Eco Mode

Lou Hamilton said:

I’ve done a few tests with my Timberline with both ECO and Normal modes. They appear to handle the same as well as provide the same MPG over the same exact routes. Not sure if it is due to the different engine and suspension, but I have seen no difference.

I know the modes work because I use Tow/Haul mode frequently and it definitely preforms as expected in that mode.

I remember my 2019 handled differently but it had the CCD suspension. I can’t speak to the MPG because I can’t specifically remember if I tested it.

Interesting, I’ve been doing the same test on mine, between fill ups and on the same route. I’ve noticed a few things
cruising at 70-72, rpm is consistent in either mode. But eco will shift to 10th slightly faster when you back off the throttle.
Where eco gets about 1-2 mpg better is around town. It will stay in 10th down to 42mph and rpm will drop to under 1k. Normal doesn’t seem to do that, it will drop to 9th under 45. I have 3.73 like you too but 22” wheels.
Eco also softens the throttle, not scientific but I do notice the less power off the line, but not bad or intrusive.
I’m averaging 17-19 combined, I expect it to improve as it breaks in a bit more.

Search through and didn't find anything specific. What does the 'eco mode' actually do? And, does it work?

Only difference I notice if I switch to it while driving is the speed slows and more throttle is needed to maintain speed.

Does it shut cylinders off?

Thanks.

You would think that if ECO got better mileage they would make that the standard at startup. Car manufacturers are doing everything they can to meet EPA standards I can't wrap my head around why they would have a mode that gets better mileage and not have that be standard?

I haven't run the eco much in a while but I don't remember thinking it made much difference for me.
