Does anyone actually like start-stop

[Sean L]

Like I said before, the potential battery issue thing is what irks me. And what about wear and tear on the starter?
Or do new cars not have starters anymore? Ugh. All this technology.
I think I'm gonna yank the 3.6 and drop in a carburated V8. Wait, cant do that because it wont pass state inspection...

I just want simple and dependable.
Hence ordering a no frills sport.

While you're running the engine swap for that carburated flathead v-8, make sure you forgo the electric starter entirely and put in a manual starting crank. Power steering pumps? They wear out, go for manual steering. Rubber tires? They wear out, go with wooden wagon wheels. Replace your headlights with whale oil lamps as well, so you won't have to replace any bulbs.

If you think of the environmental impact of idling cars i think ESS is a good idea even if the impact on gas mileage is minimal.

But it has to be seamless. It didn't bother me on the automatic Sahara i test drove.

I'll have to see how i feel on a manual.

I think it would be better with BSG but i don't want to wait until next year.

I switched from a manual to my auto (i wanted the remote start) and the first time my ess kicked in freaked me the flock out.... now while stoped it randomly starts back up just before the light turns. like the ess has learned how long a red light is. I turn it off when the temp is over 100 and i can't stand being in a hot stuff jeep. but for the most part i'm ok with it.

I miss the reference Jenn. *If* you have A/C (you may have a Sport JL), which I'd think you'd turn on it high heat, at high enough A/C setting, the ESS won't (or at least isn't expected to) engage and turn the rig off at stops.

Or maybe it's something else I'm missing.

I presume when you mentioned how the ESS learns how long the light is you meant is as a metaphor. Lifting your foot from the brake--as you probably know--is the triggering mechanism for cranking the engine up.

I love mine now it's been disabled. I don't even think of it anymore.

Having the A/C on may not necessarily override the ESS in every situation. Automatic A/C when your cabin is at the specified temperature isn't using the compressor much so the ESS will do a shutoff until your A/C needs to cool the air again. If the cabin is still hot or your A/C is set for "MAX" then it won't do an ESS shutoff. Its very dependent on the situation.

LOL such an ignorant implication. Yes, only non-hardcore jeepers won't care about it. I'm just a Starbucks (don't drink coffee) mall crawling (don't go to the mall) silly city dweller who don't know nuthin' about Jeeps. Garsh.

LOL, such a humorless implication.

@twisty and Bob, (to beat a dead horse) much as I appreciate that FCA did testing over time and weather, much as I don't know the little batteries design in terms of longevity, and the depth of its cycle, let's see how our little battery fairs up to the effects of time and cold weather in its ability to hold and deliver a charge

Yeah we're beating it but it aint quite dead yet. lol

Is there anything different in the make up of the little battery? I wanna believe it lasts a LONG time but that would fly in the face of any battery I have tried here in hot AZ. I wheel solo a good amount of the time so I need to be a little more proactive. I figure by the time I figure it out it will be time to replace. lol

When I pull into a parking spot (or garage) ESS shuts the engine off, then with foot on brake I put it in park and the engine starts, then I hit the Off button to shut it off. So I get: park car, shut OFF, restart, then shut OFF. Horrible.

The dealer told me the USgov requires ESS but this is a poor implimentation of it.

yup. Now that my defective ESS is fixed I have that same garage scenario play out on me too. There should be another S at the end of ESS for stupid. lol

Also many have said while on the road if you dont want it to shut off go easy on the brakes. Mine does not do that and shuts off even with the lightest touch of the foot pedal. So now I have to intervene every single start up to hit the button that turns it off. A new car should not annoy you.

Yes. IME, when not on max AC, the engine will usually restart after about 60 seconds or so to maintain cabin temperature.

I’ve given it a chance and am surprised it actually doesn’t bother me now. It supposedly does actually save gas. Look up “Engineering Explained” on U-tube, he recently did a video about it. Pretty convincing. Video’s called “idling explained”.

Interesting video, thanks for posting!

I wonder if the programming could change to not start the rig when it's placed in Park but rather, once in Park, if the user leaves park to engage a gear other than neutral.

There may be very good reasons I am missing as to why FCA programmed the engine to crank upon the entrance into, rather than the leaving of the Park gear that have escaped my mind for the moment.

 

[RussJeep1]

Question: if FCA had programmed the ESS to remember its state between "true cranks," would the government had issue with recognizing the ESS as a fuel economy step on FCA's part?

I define a true crank of the engine here as one the user initiates.

I appreciate that ESS might have had to be "on" by default for FCA to meet fuel guidelines on the JL, but did this "on state" (short of programming or the techniques of this forum that might light up the display panel with warnings) have to exist each time a true crank was initiated?

Haven't read all the pages of this thread so I'm not sure if this point has been covered, but my only beef with start/stop is the AC slowing down. I live in Houston where this time of the year is extremely hot... I don't blast the AC when I get in the Jeep, but it is nice to cool down a little when you're coming from outside. If I come to a stop after a few minutes of driving and the engine shuts off, the AC also slows down (I'm not sure if it blows less or the actual temp increases), and it's considerably noticeable as I go from cooling off to sweating again.

Personally, it's not that big of a deal and I can live with it. My main concern is the longevity of the battery/engine but from what I've read, it shouldn't be detrimental to the vehicle.

Do you use Automatic Temperature control in yours? I usually keep mine on that and hardly ever have it on manual control. If its blasting the A/C it won't shut the engine off, but if its just blowing a cool breeze (Cabin at your set temp) it will. It will usually start back up after about a minute or so at the stop light if the cabin warms back up.
