Can stop/start be tuned out by dealer or anyone?

Also another reason I don't like ECO is in the hot weather and your AC is on and you come to stop, the engine stops. Now the "AC" is still on. But it doesn't really blow cold anymore. And its smell changes, perhaps related to a humidity change or something. Not an elegant event to have constantly happen in your luxury sedan.

Good point but unfortunately Dynamic Mode resets to off after 6 hours I believe so every morning it need reengagement as well. It does work if you are out and about using the car on and off all day. It helps for sure keeping ECO at bay for a while.

Been using the stop/start feature and after I got over the initial anxiety of my car shutting off without warning, well I got used to it. I like the concept and Jaguar seems to have thought through the feature pretty well. The engine restarts as I am releasing the brake, which limits latency, and when it's hot and the AC is on the stop/start turns itself off to ensure the AC continues operating. The restart is smooth and sitting at a light without the engine running is actually peaceful.
If I don't want it on I can hit the shortcut button and in Dynamic mode it is automatically disabled. I'm surprised to say this but I actually like this feature.

I own the same model as jagular (13 XF, V6 SC AWD), but unlike kim-jagular-un, I don't subscribe to the idea that everyone should march to the same tune and accept everything that those who "really know what's good for us" choose to force-feed us. As for the substance of the discussion, I have two things to say:
1. I've been driving my 13 XF for more than 6 months, and I still cannot get used to the ECO feature. How long should I wait for getting used to it?
2. I don't care if this feature is a technical marvel or not, but why do they force it down my throat? So they installed it on my car, probably for some good reason (approval stamp of some agency, saving the Earth, world peace), but why won't they allow me to permanently disable it in an officially approved way, so that I don't have to disconnect the starter battery? Most Germans probably don't like the US any more than the Canadians as represented by jagular, but both BMW and Mercedes allow reprogramming of this feature. I am absolutely sure that there is a backdoor for reprogramming it in Jags as well. I hope someone finds it eventually, same as with this trick for disabling the seat belt chime (I disabled it, even though I wear my seat belt almost always).
And speaking off-topic, what is a technical marvel is Tesla, and if over the next 5 years Elon Musk solves the problem of swapping out batteries instead of charging them, it's going to be my next car, and not because it saves the planet.

This is getting too funny. Imagine Americans disliking being regulated.
And the gas guzzler tax? CAFE? Etc etc.
America is one of the most over regulated economies in the World.
Just for the record the Jaguar stop start system is also one of the best currently available.
How many brands have you tried? I'm up to four now. Jaguar's is the best I've tried.
They are all easy to live with, just not what we've been used to for forty or more years of driving, for some of us. But, hey, this ZF is the very first automatic transmission I could tolerate and now I prefer it to any manual shift. Even the DCT are better than any manual shift, ask Ferrari who no longer fits a manual or Porsche who shortly will not. BMW only makes a manual shift M5 for the US market as nobody else wants one. Fred Flintstone must still be buying cars in the US.

I'm glad you've scoured the globe for the best stop start system - given the obvious shortcomings of the Jaguar system, the others must have been truly horrendous. But, even you (yes, even you) must understand you have yourself proven the point about the shortcomings:
- Creeping up to a stop like some senior citizen who can't quite muster the strength to fully stop a vehicle - in order to AVOID the system activating.
- Citing that ZF has come up with an integrated approach to allow for electric assistance to avoid what? Well, it would seem they see an opportunity to correct and avoid some shortcomings in the current approach. "ZF already has an 8 spd with integral electric motor which will seamlessly integrate with stop start in ways even Americans will accept"
Oh, and I guess you can support the assertion about Fred Flintstone buying the cars in the US (you did say you can support all your assertions) - well, I suppose you'll find a listing in a phonebook somewhere for Fred... Hope he's doing well - you're obviously not. And how it must gall you that I have such a greater command of the written language than you, being a mere American.
Truly moronic and just a continuation of your desire to prove your idiocy.

It would be fairly easy to add a relay in parallel to the ECO OFF button that is driven by a delayed single pulse generator powered by a line that gets 12 V when the engine starts, also equipped with a hidden toggle switch for enabling/disabling this contraption (*deep breath*). I would do it, but I don't want to mess with the car while it's under warranty...

i would think the car ac compressor is driven by the engine; not so in jaguars? Anyways, i didn't lie; the ac is noticably less cool with engine off in an XFR-S. And, having the AC on does not disable ECO mode.

Just remember who you are talking with..he is never wrong and is the world famous 'know it all'..his answers are either off topic or half baked to leave it open ended for more argument to prove you're wrong... So either stand your ground or put him on ignore for peace of mind.

The stop start system technology is very slick - the problem is that it just doesn't work very smoothly...yet. V2.0 or some subsequent iteration will have the bugs worked out, but until then, it really is a shame that there isn't just a simple way for an owner to say, "thanks, but no thanks." Permanently. There are all kinds of justifications, of course, for why this is the case, but the central one is quite simple - fuel economy/emissions certifications. If Jaguar allowed a one touch "opt out" ability Jaguar wouldn't be able to post the needed numbers.
Functionally, it has all kinds of conditions where the engine gets restarted or doesn't stop at all - including ambient temperature, engine temperature, whether you're in a flat surface, turning the steering wheel, need for AC, etc. when they get the kinks worked out in terms of, primarily, the restart sensation that feels "cheap" and Prius-like, I'm sure that even we "Fred Flintstones" will have no objection...who would have known that we cartoon cave men would be so sensitive, LOL.

You're right..the A/C will not run and maintain temps if the engine is off..any other means of the A/C compressor running would have to be by an electric drive motor and I don't see that happening...it would very impractical..
