It never bothered me - the fake outrage over it is actually hilarious at times. You can turn it off, or if it bugs you that bad, buy a device that disables it. Moving along now....

All this outrage for something that can be fixed with $50...

To those writing that the Ford Performance Tune turns off ASS, I thought that ability was removed during an update. Did you not get the update (i know a bunch of people tried to stop any updates) to the tune or am I mistaken? I would love to turn it off on my 2024 WT.

If you were curious how much gas this saves I tried this with my wife.s G-wagon which doesn't come with the ASS because who wants a V8 twin turbo that saves gas anyway?

In super sport mode in gear at idle it uses .7gal/hr, in comfort mode it uses .5gal/hr and in neutral it uses around ,.3gal/hr.

I only park in gear when on a steep incline, as an added safety factor. Otherwise if parked in gear and someone hits/bumps you, the transmission can potentially get damaged. Especially city parallel parking, I've seen people banging other vehicles when trying to park. I'd rather only the brakes take the hit.
i’ve had a vehicle roll down a hill because the parking brake wasn’t sufficient.
so, wheels turned towards curb, parking brakes and tranny in either first or reverse always. it’s muscle memory at the point

I remember sitting in drive thrus when I was a kid and some people would turn off their cars while waiting. For instance, the Church's Chicken, Taco Bell and Whataburger were loooong. So we'd sit there and talk about it, does it really save gas, blah blah. So yeah, I have no doubt some people think it's nifty. Seems like a nothingburger to get worked about, though, especially since it's not that hard to defeat.

Agreed if there is a risk of rolling. Otherwise no, living in Chicago, I've seen things, lol

Had a friend from NYC who said they called tapping bumpers while parking "love taps".

I had another friend when I lived in San Fran who was a valet in downtown for seven years. That guy could parallel park! He parked a station wagon once on a 20% incline with only maybe 2-3" front and back and didn't hit either car. I wouldn't have believed it if I didn't see it. He was a magician.

To put some real numbers on it:

My truck has 34k miles, 1200 total engine hours and 300 hours of idle time (the truck logs both total engine time and idle time).

The 3.5EB, according to AI overlords, burns about 0.5gph-1gph at idle. So, in that 300 hours of idling, it's burned 150-300 gallons of gas. I'll use the lower estimate.

At $3/gallon, that's $450. At $4/gallon, its $600. Over the expected lifetime of the vehicle (150-200k) it could save ~$2000-3600 in gas. Assuming ASS engages 100% of the time.

A very decent ROI given the marginal cost of adding the functionality. ASS engaging at only, say, 25% of the time is still a decent ROI.

I don't even use the truck a lot in stop and go traffic -- for most of its life/miles it's been a toy hauler and long trip vehicle. And even when I have driven it I live in a small town with little traffic/stops compared to a big city. So my idle time is likely on the low side. It's crazy how easy it is to rack up idle time without realizing it.

I don't like ASS, but I do like having thousands in extra cash in my pocket.

From another thread on ASS here are some links to tests that investigated the fuel savings of ASS:
Edmund’s looked into that a while back and tested 3 ICE cars (not hybrids) that had AS/S on their test loop and saw ~10% fuel savings on their urban drive cycle in Orange county CA. Engineers they talked to also said the savings are typically 3-10%, which depends on how much time you drive on highway etc.

AAA also did a study of AS/S on three cars and drove EPA’s Urban test cycle and saw 7% savings with AS/S feature

Oak Ridge Nat’l Labs at Univ. Tennessee published an SAE International paper after running tests on the Federal city fuel economy test cycle and the EPA NYC test cycle and saw fuel economy savings of over 7% snd over 25% respectively.

So it has been proven to save fuel, and it reduces emissions, tho how much savings depends on the vehicle and driving conditions. Also as @Ducati1098 pointed out, Ford did reengineer parts for AS/S, and i know durability test procedures were revised for it.

Still, the fact also remains that a lot of people just don’t like it and don’t like that it is always enabled by default.

Frustrating thing with an inline device is pulling the console apart. Increases risks of breakage and forces people to pay extra to disable an irritant.

At least on the Jag, people could just remove the extra battery (which the manuals never had to begin with since Jag was smart enough not to even enable it on the sticks).

With today’s deregulation in the EPA that lead the automaker’s implementation of the Auto Start/Stop feature, wonder if Dealers will begin disabling it upon request?
Who cares, just disable it yourself through Forscan or the little piggyback part... I've done it to both our Bronco's and the Ranger when we had it...

It had nothing to do with an update. I’m pretty sure it simply goes off build date (or something similar)

I’ve installed a handful in the last few months at work. Some still remember the last ASS setting, others don’t.

From what I’ve seen it works far more often on earlier models (21-22, maybe some 23’s?) than later ones, which is why I think it’s based off build date.

I’ve had my Bronco almost ten months and I still forget to press that damn button at least once every day. It’s annoying.

Ok send me $50, then for my part I'll squelch the so called "outrage". ;)

Although I'd rather you send me $100 for the better kit that doesn't work off the OBD port, and while your at it stop by to take apart the dash and install it.
How very "social" of you to demand that others pay for it and/or disable it for you, especially when you already have a button that can disable it for your driving session. Did you want someone to stop by and push the button every time you got in your Bronco?

I would love that, they should also be an ex EPA employee.
