I was really impressed with the improvements and now very disappointed.
Also my Oil Change monitor went from 70% to 14% in the same time frame.
So after only 3500 highway miles since my first oil change I am back in for another oil change.
The first one was at 8200 miles.
I hope this was not a big mistake getting A JGC.
This is my first Jeep and I am not feeling real good about it.
2014 Jeep Grand Cherokee Limited.
V6 "Trail Rated"
That's exactly how I feel. You can't judge it on the way from the dealer wait a week.
We may be seeing more effect from the Dealer wiping Adaptive Memory than the Update itself.
I'm starting to think it's more about Fuel Mixture than Shift Points. The erratic power available throws the shifting (and driver) off so that it appears to be shift points.
It's been cool lately but not that cool.
This morning I took off from a light (after 15 min warm up) and it gave that Turbo Lag feel (quite bad actually). And I look down and I'm still in 2nd Gear and Moving !!! Other times if I'm moving in 2nd Gear the thing is a beast. It has to be fuel mixture to have so little power in 2nd gear while moving.
It has to be fuel mixture that it's playing with. When ECO mode is off I think it backs off the fuel mixture tweaks to improve MPG. Along with slight adjustments to shift points. I believe the Shift Points are actually fine with ECO Mode on. But the Fuel Mixture adjustments are messed up. Or a bad senor it uses in Eco mode is sending erratic info.
I think the weather changing might be impacting the ECO Mode Fuel Mixture. I might pull battery off again and see if it runs good for a week again. Because it did run good for a while. Almost as good as ECO Off.
Mine seemed to go down hill the next morning after taking a Trailer off from the prior evening. Perhaps the Adaptive thing learned something it shouldn't while the Trailer was on.
