Hello to all

I just learned today that the ECO MOde on our 2010 JK's , restricts the ability the cost to a stop, instead it cuts the fuel , and stops the Jeep faster, while some might find this feature useful, it is anoying in vermont , where there are many mountainious hills and driving with this feature is not only enoying to me , it is causing the tranny to downshift on its own, see the attached link. I originally thought it had something to do with the hill assist feature, I was wrong, it clearly seems the be this , as what Chrysler states the operation of the Fuel Cut-off feature does. I know it is a Canada Website, but we have this same option in the states as well.

Does anyone on here know if the dealer can turn this program off??? Most vehicles when let off the accerlator , they cost to a stop. Sorry for posting this issue more than once, but this feature is becoming very enoying while driving.

Thanks for any help in advance...

 

My 2011 has the option to disable the ECO through the personal settings. I know the 2010s don't have that option but at least it's possible on 2011 so maybe the dealer can do 2010s.

 

I'm glad i have the 09...

The only way I save gas is not driving...

 

Hopefully my dealer would understand what to do on the re-programming to dis-able it. By your 2011 having the option to disable it on the dash tells me I am not the only one who does not want this option on...lol

 

AMEN to that. Between the hill assist brake control sticking and now this eco control garbage, too much control over my driving...lol

 

EFI engines have been doing that for decades. I've run diagnostic loggers on cars from the 90s that zero the delivered fuel when the throttle position zeroes, and read books about FI systems from the 70s that claimed those systems did the same. I like it. It should increase engine braking and I can always toss the tranny in neutral or hold partial throttle if I want to slow more gradually.

 

huuummmmm,, I understand your point, but when you need to acceralte going down hill , to overcome this system, " because this ECO System is actually got you sometimes 5 or 10 mph under the speed limit" ,,,,, does not make sense.

I drove many vehicles including big rigs at work, and I always get the best ,mileage buy not speeding up to redlights or going over the speed limit, or accelating " JACK Rabbit starts", etc. This is the first vehicle were so much control over the engine and drive train. I love my Jeep, but not this ECO Garbage.

NOt finding fault with the system, just is not for me.... lol

 

I agree with this.

To me, having the ECU deliver gas even though you've got your foot off the throttle is having the ECU drive for you. I don't want it to have that much control over my driving. Holding a little bit of throttle doesn't mean you will accelerate... if your throttle position doesn't overcome drag/rolling resistance you'll smoothly decelerate at a rate based on your throttle position. If you have a red well ahead of you, ease off the gas until you are going a speed you think will give the light time to turn green for you. How much you ease off, from almost holding speed to full engine braking, is your choice and should be dictated by your judgment, not the ECU thinking you want more gas than you are signaling.

I suspect it's just a matter of what you are used to. I've been driving vehicles that did this for years. Diesel and gas, large vehicle and small. I've always thought it was one of the principle benefits of going away from carburetors and 100% mechanical diesel injection systems. It's actually one of the main reasons I didn't like driving American cars and especially Automatic transmissions...the disconnect between what I told the car to do and what it actually did bugged me.

This is totally different from the hill start, which I don't like for exactly the reason I do like this.

 

I also found this kind of different and irritating while coasting to a stop. After I installed my Superchips it has gone away and is not noticeable in the 87 octane tune.

 

Thanks for the info. Seems like there might be some hope at the dealer when I get free time to get there. It is almost like driving with your acceraltor and brake pedals at the same time in some cases. If the dealer can not help me, then I will take your advice and put a programmer in my Jeep.

Little by little they are taking away our enjoyment in driving with all of this tech garbage, not impressed, Thought it was just me who had this issue with the JK...... .......,,lol
