ECO mode, fuel saving mode not working

[Redfour5]

About 800 miles now, 6 days of use and I haven't seen the green "ECO" emblem but once. I have it selected in the settings, it's just not coming on. Is it restricted during break-in or something?

On 3.21 rear ended units it comes on a lot less than on 3.92's based upon my personal experience and quite a few posts.

Mine works when cruising on a flat smooth road with little head/cross wind under 60mph

Mine comes on all the time it seems.

Bought a used 2021 with 7500mi. Haven't seen the light yet and have driven it about 150mi. Mine has CAI and borla exhaust. Would this effect econ?

WOW! You resurrected a TWO YEAR OLD thread!

What's your point? It means he's using the search function instead of making a new thread about an old problem. Win - win if you ask me.

Mine will stay in eco mode up to 75 mph on flat stretches of hwy with no headwind. Once I get above 75, the eco will still kick in now and then depending on grade. I have the non-etorque Hemi with 3:92 rear end though. I did notice that eco started coming on more often after the first 3000 miles, so it seems to get better after good break-in.
