Aero mode even with ECO off?

I thought I read somewhere that the Aero ride height is only achieved when Eco mode is on. Am I mistaken? Because my vehicle goes into Aero mode on the highway whether Eco is on or off.

Aero mode operation isn't affected by whether Eco is on or off.

I believe with ECO off Aero kicks in at a higher speed. Of course it always kicks in when in Sport mode.

Actually, several of us have tested this, and it goes into aero-mode at the same speed regardless of Eco-mode.

So there's no way to stop my vehicle from going into Aero mode at highway speeds? Really?

Re: Aero mode even with ECO off?

Aero mode occurs at a different speed in ECO and ECO Off for a 2014. With ECO ON, it goes into aero at 50mph after about 20 sustained seconds at 50 or above. I think at 56 or higher, it goes right in to aero mode without waiting the 20 seconds. With ECO OFF, it doesn't enter aero at all until reaching about 60mph, could be as high as 62. Often, I will disengage ECO if I know that I will be stopping at a light or something like that when at 50 or a little above to prevent cycling the air suspension up and down. I may even use the paddle shifters for a little extra control to keep in a higher gear somewhat compensating for ECO being OFF. In other words I use the control available to both save gas and reduce wear and tear. It is second nature after a while. If I stop, or slow down, I re-engage ECO again.

I've noticed no difference in when it goes into aero on my '14..ECO on or off. I HAVE noticed that the programming seems to be a little more interesting than the boilerplate description as a hard, fast acceleration seems to sometimes induce an "early" drop into aero if I'm approaching its normal engagement range. Again, that's with or without ECO being on.

Remove the air suspension and replace it with standard springs and shocks should work.

Does it matter? I mean what reason would you have to want it not to go into aero mode?

Don't kid yourself. That's exactly what a lot of people will do when their warranty is up and the air suspension fails. Look for "air spring to coil spring conversion" threads in the future. That's a lock for sure

I didn't say that I didn't want it to go into Aero mode. I simply asked a question about it.

But anyway, I think they should have designed the system to go into Aero mode when at highway speeds in eco mode and had the ability to disengage Aero mode when Eco mode is off. Actually, I could quite easily make that modification myself, as it would be very simple.

Haven't seen it yet. You may have a '15, but there are an awful lot of out of warranty Jeeps already on the road with Quadra-Lift.

Why do you think it should be designed with the ability to shut aero mode off? Just because they could have, or do you have something in mind.

For me, if it wasn't for the little message in the cluster I would never know I was in aero mode.
