Have you seen any benefits from ECO mode? If so, what?

[1337logan]

I have a 6.7, run eco mode often but haven't bothered to measure anything in terms of milage difference.
Does anyone have any experience with this?

So far it only burns more battery to power the green LED to show I'm in ECO mode. Haven't seen any improvements in MPG or range when using it yet. Anymore I don't bother to switch into that mode.

I ran in ECO mode for about a month straight. I did not notice any difference in fuel mileage.

The economy benefits. Lol

It's probably mainly a throttle/shift point calibration.

It makes me feel far superior to people who don’t ?

stopped using it day 2 when I perceived it used more fuel.......

I've been testing ECO mode for the last couple of weeks. I need more time to confirm anything. I think it might make the gas pedal it little more "mushy" which helps you easy up to speed from a stop. The gearing might be a bit different as well which would result in less bottom end power but slightly better fuel economy. Overall, I think when you are driving around town to pick up groceries and drop off kids at practice, ECO mode may aid you to have better driving habits in constant stop and go situations. When I say better, I mean "better" in terms of fuel consumption/MPG.

On the 7.3 it seems to hold it in 10th longer. Anywhere between 40-60 is where I noticed most so far. Only had the truck a week so it’s a very early observation. When I give the truck a bit of gas, like 1/3 ish while in eco mode it will stay in 10th. Give it the same gas in normal mode and it drops to 8th. Seems like it will upshift faster and downshift slower in eco mode to keep the RPMs lower longer.

Based on my experience, that makes perfect sense.

I agree. I don't think you can accelerate as fast with eco. On freeway driving in a straight line at a steady speed I doubt it will do much.

I don't have a typical driving route so I can't test ituch past the seat of the pants.

Ive used it quite a few times, and in the city I find it annoying, but on the highway yes ive noticed a slight increase in MPG, it holds higher gears longer, and changes throttle mapping so when you push on the throttle say half way its only actually giving you a quarter throttle. But in an emergency situation if you stab the skinny pedal it will give you full power to get out of the way or pass someone.

It feels like it makes pedal lag worse, especially at highway speed. I went to change lanes on the freeway and pressed the accelerator to speed up and it damn near felt like the truck shut down for a second, then down shifted and jumped. It was very scary and I do not use it any more. I have a pedal monster on its way so I may try it again with that installed.

Man you are definitely a true believer
