Stop / Start

[bocco]

New guy here. Shopping new Rams. I really wanted the eTorque but I may do without it since I'm having trouble finding one with the rest of the options I'm looking for.

My question is, does the non eTorque 5.7 come with the stop / start deal? And will I need the under dash plug in gadget to disable it?

Thanks

I have the 5.7 w/eTorque and cant saw 100% but i think all new cars pretty much have it so I would say yes, even without eTorque it has it. Having had 5 cars so far with auto start/stop, my RAM with eTorque is the first one that I leave it on because its so fast it does not bother me at all. I think the eTorque battery is probably the reason for that. Don't know how it would be without it. But you can not disable it permanently, its "persistent". You would have to press the button to disable it each time you start the vehicle unless you get some gadget on the ODB2 port that does it.

Only the eTorque engines have start/stop. The EcoDiesel and regular Hemi do not.
You can quickly tell whether a particular truck has or or not by looking near the gear shift knob. Those with start/stop with have a button to enable/disable it. The button has a letter A with a circular arrow.

Actually, the start/stop can easily be disabled so you don't have to press the button each time. Autostop Eliminator works flawlessly with the system to eliminate the need to press a button every time you start the truck. We have two of them in our 2020's and they work flawlessly. Less than five minutes to install...if you can plug a Cat 5 cable into your computer,then you can install the Eliminator as there is no cutting or splicing required.

Just bought a 5.7 last week. Happy to say it does not have ESS.

Spot on.

Why specifically look for an eTorque engine if you want to disable to whole point of the eTorque? If you don't want the start/stop, get a regular Hemi.

Slim pickings nowadays. Inventory is low and he may not be able to find one without it for months.

That is a heck of a lot more benefit from the eTorque than just the start/stop system. You should watch the video circulating on this forum about all of the capabilities of eTorque as the start/stop system is minor compared to what the rest of the system offers.

We own two eTorque Rams we purchased over the base 5.7L as the eTorque makes the 5.7L a much better system with smoother starts from a standing stop, smoother shifts, ability to hold ECO mode longer, etc. IMHO eTorque - minutes stop/start - makes for a much more pleasant driving experience. Also, this system has a ton of future potential and I’m betting on the fact there are be a number of aftermarket upgrades in the future that can be added to the eTorque system...

" ability to hold ECO mode longer"

Curious. Why would eTorque enable the engine to hold ECO? ECO light is just signaling cylinder deactivation (MDS). Pretty sure there's no correlation between the two systems.

I would be fine with Stop/start on an eTorque because the whole system is designed to do that and it's belt driven. I don't want stop/start on a non eTorque as I feel it's just beating the hell out of a traditional starter.

eTorque still uses a traditional starter

It does not. It uses a box that replaces the alternator. I'm not sure how it all works with the 48V battery but that box is what restarts the truck from an auto-stop.

It is much faster and smoother than using the starter. When you lift your foot off the brake it starts the truck quickly (400ms?) so that by the time your foot gets to the gas pedal the engine's already up to speed and ready to go. You don't have to hesitate to let the engine finish starting up before you give it some gas (unless you're really quick).

Way better than standard start/stop with the starter.

“that box” that replaces the alternator is called the Brake Start Generator (BSG).

It essentially gives the engine a “slight tug” to aid in smoother starting. This is in combination with a traditional starter

OK. Can somebody with eTorque crawl under their truck and see they can find a starter motor? Actually I would think it would be obvious by the different sound.

This is interesting I was unaware that it used the traditional starter along with the etorque generator. Good to know.

Many vehicles these days have start/stop without an E-Torque like system, however they have heavy duty starters, AGM deeper cycle type batteries and in cases like Fords Ecoboost, an upper valve-train designed to hold oil longer. Which is why you need to wait at least 15 minutes just to check the oil on those engines.

In short, if you are worried about hurting the vehicle due to the start/stop procedure, don't, they are designed to do it.

I asked my Service Manager the same question and his response was the eTorque system helps keep you in 4 cylinder (ECO) mode longer. I wasn’t certain he was correct but my eyes and butt don’t lie when running in ECO mode. So, I found the following which also appears to indicate there is a correlation between the two systems.

“As it has been for many years, the HEMI V8 is equipped with a cylinder deactivation system that can shut off four cylinders during light load conditions. However, since most roads aren’t completely level, the engine often ends up cycling back and forth between four and eight cylinder modes. With the mild hybrid system, the BSG can give the engine enough of a boost on gentle grades to keep the engine in four cylinder mode to keep the other four cylinders shut down.” In simple terms, it may not keep you in ECO mode longer in the Rockies or the Texas hill country but it does help you stay in ECO mode longer in the flats like the Gulf Coast.

Isn't one of the advantages of the eTorque system is that it adds low-end torque? I can't be sure, but I seem to recall reading that somewhere. If that's true, then the torque added to the engine by the eTorque system could what helps the engine stay in ECO at lower speeds.

Just my $0.02 (before tax). YMMV.

“The Hemi's eTorque motor is good for 16 horses and 49 lb-ft and, again, multiplied through a slightly different ratio for an assist of 130 lb-ft.”
