How to take advantage of ESS effectively.

[BillyHW]

@BillyHW ... Shane looks to be about 30ish years old. He presented well and was very knowledgeable. He knew I was pretty familiar with the set-up in the JL, in regards to the aux battery, ESS etc.. I tried to get him to stumble by asking pointed questions and no, no stumble but direct knowledgeable answers to my questions, etc.. He seemed very, lets say, on top of things....

I actually mentioned to him, that a canuck on JL Wrangler forum was very worried about how the "Genesis" dual battery setup on the JL would perform. Anyway, he said to pass on that the "boost button" and all, with the JL, works flawlessly. He mentioned you will not find yourself in a position with the Genesis where your JL would not start. Again, we talked about the dead or missing aux battery and main does not start the JL. As I mentioned earlier when you install the Genesis set-up you no longer have that little aux battery..

You might consider emailing Shane.. He will undoubtedly will reply to your questions and concerns..

It will be interesting to see how the wiring will actually work with the kit. I'm assuming that the Second battery is just hooked up to the same circuit as the Small Aux battery was, and will perform the same duties. There will be more to it, of course, because he's also got a smart isolator between them. And it starts to sound really complicated when you consider that the stock wiring charges the Aux battery in some way already, and the kit's wiring does that too already...so it's charging from two different systems?

But we shall have to wait and see how it all works.

Unfortunately, as you can tell by my avatar, I'm a very impatient and anxious person. I will try to wait until it's actually out and there's some documentation released before hounding him with questions.

After you get used to it, it's really great. Dash still showing 21 MPGs coming up on my 3rd fillup. Most fuel efficient 4x4 I've ever owned.

See, that's great and all, but no word of a lie I'm on about my 3rd or 4th fillup right now, and I turn my ESS off every single trip I take whether it's not even a mile to work or 300+ mile roadtrip over the weekend - I'm sitting at 20-and-change MPG.

I'm not seeing any sizable benefit, at least comparing our two anecdotes. And in my mind, the little annoyances that it does cause no matter how used to it you get are just not worth some fraction of half a single MPG.

So my questions are


Does ESS improve gas mileage than not using it?

Is using ESS going to cause more wear and tear on the engine? I always heard that if you were stopped for a few minutes you might as well leave the engine on, and also saves gas versus turning the engine off and on again.

What's the point of ESS? Why did Jeep put that feature in the JL?

Good tips bro, still waiting on my delivery. But at least I'll know some things ahead of time.

As for ESS Im indifferent. It shouldnt have been a surprise to anyone that Jeep added it in. Its not like they didnt menetion it, when the JL was revealed. But people still bought JLs, knowing they were going to have to learn to live with it. Myself though I pay to play, and if I cared about fuel economy Id buy a small sedan.

If ESS bothered you people that much, Jeep still offered the 2018 JK's without them. Y'all could have bought those, and saved your precious fingers from the pain and agony, of having to press the ESS button everytime you got in the JL.

Thanks again for the tips Sean, good shit

 

[JEEPJL]

ESS has zero inconvenience with me , If it does in fact help with mpg and emission's than I'm all for it .

Good Thread @Sean L !!

Its modern Jeep in a modern world .....If it goes against decades of muscle memory than people will complain about it

 

[HardRock]

ESS just plain sucks. It is only there to get this Jeep to do better on the over regulated EPA requirements. It is hard on the engine, it is annoying, it adds cost to the initial purchase of the vehicle, and increases future maintenance cost.

The only good ESS is a DISBALED ESS.

Sorry I can't give you a non "big Grumpy Cat response".

Exactly.

Its not just a Jeep thing - they are in a lot of models and its very annoying. No reason to like it - there should be a setting to disable.

I have a feeling you know you're being ridiculous with this comment given how many other improvements make the JL worth a purchase over a JK, so I won't address that in hopes that your own sense of humanity will take care of that.

So I'll just speak for myself as someone who turns ESS off every trip: I don't mind pressing the button, though not having to would, of course, be better. My wife and I have kind of made it a game; turning on the Jeep and pressing all its dang buttons is like booting up a space shuttle for launch (I kid, obviously, but all these screens and stuff are getting crazy). We have a little routine down every time - push start button, she pushes the ESS button, pushes her heated seat, I hit the Uconnect "accept" button...lol

And with such (anecdotally, for now) little evidence that it makes any kind of real difference in MPG, I don't understand how people could love it, logically. Coming from an age where everything was a manual and your car turning off was a sure sign you messed up, I guess I'm biased, but I don't understand what you guys are getting out of this.

Do you just love that eerie feel of no engine right before you get that green light to merge onto an interstate highway at 70mph? Or not having your engine on when some idiot comes barreling at you through a stop sign (true story for me, unfortunately)?All for the sake of .10 more mpg than the guy next to you whose engine is running, ready for the quick merge and not having to concentrate on feathering his brake or how lightly he's pressing the brake? I don't care how good you are: using the ESS delays your ability to get going quickly. That's a fact. And in dangerous situations, some fraction of a second could prove harmful to you and/or your passengers. People who have been in accidents at lights and stop signs and other situations where you are stopped know this, so please don't try to speculate if it hasn't happened to you, or at least acknowledge that you don't have that experience.

lol... I'm not going to get into why it's hard on an engine to start and stop it over and over. If you believe your statement, I can't help you.

What data do you have support this supposition. A good design can easily deliver high reliability. It’s also pervasive technology in the auto industry today. I appreciate that change is sometimes difficult but this is independent of the viability of the technology. I happen to hold the belief that the cost of the feature greatly outweighs the benefits, but that’s only my opinion and I don’t have to deal with the government regulations.

 

[jaldeborgh]

I will agree that the ESS is probably the silliest way for automakers to deal with somewhat artificial and watered down regulations. A much better way would be to improve the aerodynamic properties of the flying brick, or to reduce weight by going with an IFS or eliminating the roll bar and reinforced, removable top. But since these were non-starters for the Wrangler (else, why bother making a Wrangler?), Jeep, like so many other automakers, took the easy way out and went for an incremental benefit, using ESS.

This is the price we all pay for allowing car makers to be so damn lazy for the past 5 decades. The 1970's taught the American consumer nothing. We should be far more demanding when it comes to tech that decreases waste and consumption. As long as we love to guzzle gas, we will empower foreign nations through our oil dependency. The CAFE regs were designed to reduce dependency on foreign oil, but we fight them so much that they effectively become(through "hacks" and dollar votes) and will officially become through deregulation) impotent.

ESS is, like you say, a "minuscule MPG improvement", especially considering all the tech that went into it. This, of course, doesn't take into account the environmental benefits in large cities of removing thousands of idling vehicles and the tons of CO they produce. But, leave this out of it for now. The fact is, we absolutely should be demanding more than ESS form carmakers, or, very soon, we won't have to worry about IC engines at all, because everything we drive will be electric...

The only flaw in your logic, which is reasonable, is the benefits of ESS are incremental to any other improvements and the auto companies are fighting for every 0.001 MPG they can muster. It’s all about their fleet average.

 

[schneidvegas]

If you find stopping at a stop light distracting then I don't know how to help you.

I’ll read through this later but I love ESS. I’ve used the ESS technology since 2015. I did 6 months with it turned off on my last vehicle and my mpg went down by 6 so I think it’s beneficial for me. As you pointed out, this shouldn’t be distracting at all...

The change can seem incremental, but the difference of even a few tenths if a mile per gallon does make a difference when it starts to propogate across an entire vehicle fleet. Major metro areas are waiting on fleet turnover to help reduce emissions to try and meet ozone standards which were lowered last year. There are limited avenues to reduce emissions from industrial sources further, but industry can be seriously impacted in a city that is not compliant with ozone standards. Some will just say the EPA is over reaching, but there is abundant evidence that improvement to air pollution correlates with improvements to the economy and more than ample evidence that air pollution is bad for health. Me personally, I like being outdoors where I live, and being able to see the mountains, and not have my chest hurt the next day if I decide to run around outside. If I turn off ESS, I know it won't make a very big difference, but everyone making a choice to do things a little better does make a difference. Most people who get a Jeep enjoy the outdoors, so I wonder why the resistance to making the outdoors a little better?

Don't get me wrong, I am 100% for any improvement to reducing fuel consumption and CO2 production. Just playing devil's advocate a bit, and pointing out with the money available to car makers for r and d, and the looming CAFE regs, I believe they could do better than stop/start. And they will, a soon as we all stop complaining about the current "inconvenience" of ESS. I, myself, can't wait to see the hybrid Wrangler. That will certainly tear a great rift between the staunch tradionalists here and the more progressive minded folks, of which I consider myself a part.

We all spent too many years in love with huge V8s and 4 barrel carburetors, over weight cars that rusted out and became disposable and inefficient emission systems. Our penance is ESS. I'll pay that price happily. Greater pains are coming.

If you sit around the house and eat bacon 3 meals a day for 30 years, one of two things is going to happen: you're going to drop dead (as IC engines just might), or you're going to get your ass off the couch, eat a salad and lose some weight. There is very little middle ground.

Nope, you're right. Clean air is good. I know my little recycling bin doesn't make a big dent, but I fill it anyway, because I've seen the Great Pacific Garbage patch. I return my beer bottles because I want my nickel back (but not Nickelback, because they're terrible). I will not disable my ESS, and I look forward to the other, newer and more effective minor inconveniences to come.
No worthwhile change comes without pain.
