Re: How to drive 2014 8-Speed 3.6L V6 in ECO Mode

I wonder if interrupting the adaptive learning cycle with battery/fuse disconnects might actually hurt the process. It's been said it can take up to several thousand miles to smooth out the adaptive learning curve. Each time you disconnect I would think it starts everything back at square one. Maybe letting it learn while you learn to adjust to the new mechanics of the 8 speed might be a better way to come to a middle ground with this system. Just a thought. I'm on the original software, and have never rebooted the controller, and I'm liking the way it behaves.

Re: How to drive 2014 8-Speed 3.6L V6 in ECO Mode

The number of variables we have to deal with in order to get the sort of shifting behavior we each want out of these vehicles seems to be endless. The vast majority of them operate within modules and engine/transmission housings. Many might agree that these often feel like uncontrolled variables.

But, I think that there is a significant controlled variable in the mix and that the OP is onto something here. We be the controlled variable.

Driving in ECO mode, as in not hitting the button to turn it off or not going into Sport mode is, in my view, something of a statement of intent. It suggests that getting better mileage is a priority. Sure, there are people who simply don't want to mess with having to disengage ECO every time they crank the car up, but who also like to stick their foot in it. But still, having an illuminated button on the dash panel that says ECO sounds to me like a statement, even if it is a statement by omission.

And folks who have a thought of economy floating around loosely in their mind are very likely to drive more like they have an egg under their throttle foot than as though every green light looks like the starting light tree at the local drag strip.

I have about 3,500 miles on my Overland and I have had the most recent flash. Can't complain about ECO anymore. But, prior to the flash, it was beginning to become clear to me that all the miles I drove in ECO where it seemed to short shift or clunk on down shifts in parking lots or stop and go traffic were miles that I drove with a light throttle foot. The last 1,000 or so miles prior to the flash were more like I drove my Honda S2000 and the shifting was smoothing out. By the time I went in for the flash, ECO mode gremlins were rare. Since the flash, they are virtually non existent. I leave it in ECO mode for everything but twistys and I still feel like I am in the right gear for what i want to do 99% of the time.

I had thoughts about doing my own version of this post a while back. Kudos to the OP for suggesting that we as drivers might have a role to play in the performance of our GCs.

YES, exactly. I think it's just deferring getting the Adaptation Job done.

Re: How to drive 2014 8-Speed 3.6L V6 in ECO Mode

I regularly get 14 mpg city, and 18 mpg highway, but regularly outduel grandmas at stoplights.

YMMV.

Eco mode can't cause an accident. The driver can cause an accident though...

This thread is not about that.

Obviously, the OP can speak for himself. We owned a 2004 VW Passatt 4Motion that had serious and legendary transmission shift problems right out of the box. On one occasion, my wife accelerated to merge into freeway traffic and the power delivery simply paused for 3-5 seconds. That left her pulling into the right lane off a freeway at 50 miles an hour and suddenly losing forward momentum in front of traffic closing on her.

Any significant loss of forward momentum is troubling. The same event while surrounded by cars that expect you to maintain a certain speed is easily a potential cause for an accident.
