Eliminating START/STOP

Been using the Smart StopStart for six years now, works flawlessly:

I think they only offered incentives but never made it a mandate. But I’m guessing you already know that.

I don't know, but my guess on the subject is that @AndySpill is now searching whether EPA regs actually deal with reversion to default ESS at shutoff.

This could be something that is a factor, however small, that goes into a manufacturer's fleet or model mpg calculation, or it might not.

Ya, it doesnt work like that in 4lo. And lights on the dash are more irritating for me than ESS. Lol.
JScan is super cheap and gets rid of that TPMS light as well. Are you running with d9fferent size tires? Jscan fixes that, as well.

The stock tires were nearly 32" in diameter highway tread. I replaced them with nearly 33" all terrain tires. The difference in mph is negligible (;ess tahn 1 mph difference. Can you clear a warning code without "fixing the problem" with Jscan??? I know there is a device available for about $300 taht will allow you to recalibrate the tire pressure alarm but thus far I just run with reduced pressure and ignore the light telling me to inflate them to 36psi.

I have to confess if the battery discussions are longer than a paragraph my eyes glaze over and I stop reading. Gone are the days when you just put in whatever name brand battery was available and didn’t give it another thought.

Anyone try this plug in?

I use this on my 2025 3.6L and it works great. No issues.

What led you to choose this over the other two major choices?

Sorry, I actually use the one Tim linked:

Just wanted to say that these eliminations in general don't cause any issues. All they do is remember the stop/start button can signal command and send it upon key on. It's the same as if you pushed the button every time you got into it.

I'm lazy so I spent the $100.

You can clear codes with JScan but if its reoccurring, well, you'll be clearing it a lot. I dont think there are any code readers that let you just clear and ignore. Thats seems a little odd. Lol.
While that <1 mph difference, it's still affecting overall mileage and that means odometer won't be accurate.
TPMS is easy with JScan. All said and done you can get set up for like $100. And it does a shut ton more stuff. Paired with a start stop device, it meets most people's needs. I personally dont mind the ESS so I've never been concerned with it.

To each his own though. I hate dash lights so here I sit. Lol.

Nope, he's not searching, because he knows, as many of us do, that in order for the ICE automobile manufacture's engine start stop system to allow those manufacturers to report the more favorable MPG ratings of using this system on a vehicle's Malroney sticker, that start stop system, in addition to a whole bunch of other requirements, must default to being "on" (capable of being engaged) with each cold crank. The ESS term is "non-latching" as it relates to the ESS on/off button. The button doesn't remember its state the last time the vehicle was operating, on or off, always defaulting to "on"

Now, that 15 other reasons may prevent it from engaging, by design or poor design, or that 15 manufacturers may develop aftermarket tech to remember the button's state from one cold crank to the next, that's a story for another day.

. . . . he knows, as many of us do, that in order for the ICE automobile manufacture's engine start stop system to allow those manufacturers to report the more favorable MPG ratings of using this system on a vehicle's Malroney sticker, that start stop system, in addition to a whole bunch of other requirements, must default to being "on" (capable of being engaged) with each cold crank.

Does "he" and the "many of us" know that ESS is not required in vehicles, and that an ESS system which is the "predominant operating mode" qualifies for government calculation credit? See the relevant CFR, particularly § 86.1869-12 (b) (4) (iii), titled "Engine Idle Start Stop."

Less than 5 minutes of internet search for me to find. Note, this optional "credit" applies to reduction of carbon dioxide emissions, and does not refer to mpg calculations that a manufacturer reports. We all learn from actual facts.

I think you're trying to share that ESS systems are not mandated, just, if installed by manufacturers using EPA guidelines, a way of lawfully allowing an ICE automobile manufacturer to report more favorable MPG ratings on their vehicles. I believe that such an optional system, if meeting EPA criteria, allows an average MPG of that seen with ESS systems engaged and not to appear on the Malroney sticker.

I believe you wrong that the EPA doesn't refer to mpg calculations that a manufacturer provides...sort of..but only because such mpg testing can also be done by the EPA as well, no that manufacturers don't provide it.

Yes, I'm aware that manufactures need not incorporate start stop technology. EPA CAFE standards dictate what fleet MPG metrics must be without the manufacturer incurring penalty, not the (lawful) methods that said manufacturer takes to accomplish that goal, including the purchase of tax credits from other manufacturers that exceeds their metrics. One such method manufacturers are allowed, but again not mandated to use, is an EPA complaint engine start stop system.
