Curious why Jeep doesn't make this an on / off switch without a default ? ... Similar to Tow / Haul mode.

The 2014 Jeep Grand Cherokee features a new Eco Mode that contributes to its improved fuel economy. Eco Mode optimizes the Grand Cherokee transmission's shift schedule and - in V-8 models - Fuel Saver Technology with cylinder deactivation as well as throttle sensitivity to maximize fuel economy. The Eco Mode also manages interactive deceleration fuel shut-off (IDFSO), which cuts fuel delivery when the vehicle is coasting to reduce fuel consumption.

In addition, the Eco Mode activates the vehicle's air suspension system (if so equipped), lowering the Jeep Grand Cherokee to "Aero Ride Height" earlier to improve fuel economy.

Eco Mode is automatically engaged upon vehicle startup. A button on the center stack allows driver's to disengage Eco Mode if more spirited performance is desired.

Perhaps the Feds want it defaulted to eco to save fuel. You then have to consciously take an action on every startup to use more fuel.

Other than the early aero suspension mode, I think pre 2014 employed the same kinds of Eco mode features when the cruise control was engaged... well at least on the V8s.

Seems now there is another button to click off every time you start up. Do 2014s have a select trac sport mode?

Then we should be able to set the default on the EVIC...

This alone makes me want the turbo diesel... I'm reading tunes on a TD can fetch another 50hp/100 lb tq.

The diablo tuner can program those features on the 2011-2012 5.7 (typically disable them). Is there a tuner available for the CRD?

There's a whole thread on this in the diesel section if you're interested. I don't know how to post links.

If you have not done the battery cable reset give that a try and then just give it time it will smooth out. I had 1-2-3 upshifting issues with my 5.7 and it didn't really feel normal until after the battery cable reset and 3000-4000 miles. I know long time to wait but it will likely smooth out. the V6 is a different story that one has bigger issues needing software updates

I think I left it about 2 hours, probably doesn't even need that long I think a lot of people were doing like 20 minutes or something like that. after you hook it back up idle like 5 minutes and then slow easy drive around the neighborhood with stop signs for 3 or 4 miles. don't just hook it up and jump on the highway going 75 that gave a bad result. I think the thought pattern is that there is some type of immediate learning that goes on within the first few minutes after hooking it back up. sounds stupid I know but did seem to give benefit to a lot of us. good luck

here is thread that is related

No default off and give the transmission some time to break in and adjust to your driving habits. I wasn't too fond of how it shifted when I first got it, but now with nearly 13k miles on it, I never get a rough shift and it smoothly transitions through all 8 gears. I think around 1,500 - 2,000 mile marker I saw a big improvement with the tranny.

I will leave it in ECO Mode when I doubt there will be a need for quick power, the active Sport Mode other times. I've found I now rarely use Normal Mode. Sport Mode is excellent, giving very quick response with no hesitation. The BMW people with the 8-speed have reported problems with delays long enough that people are honking at them, something we do not need to worry about.

I'm sorry but I see absolutely no point in this. I drove gm suv's when they brought that out and they hardly ever went into afm, I'm sure they have gotten it to work more but still. Unless the gm version does not work near as good as the mds in hemi's I see no reason to disable it. The only time it comes on is under low loads when you don't need the power. I have it on my Ram, I have never one time felt like it delayed power. There is much of a delay when the traction control kicks in than mds. It goes straight from mds being on to rear tires spinning instantaneously.
Now if you want to talk about removing torque management I am 100% all for that.
