The OEMs typically aren't allowed to permit permanent disabling of this feature, since it is factored into the vehicles published fuel economy rating.

Why would you want to?

 

It's getting to be a PITA to disable it every time I start the vehicle.

 

I hate this on my f150! Drives me nuts. I cannot believe that button isn’t a permanent off/on. Like “I accept lower mpg and less engine starts”

 

I highly recommend, simply for your sanity, that you try and embrace the feature, rather than fight it. I didn't like it on my Forester when we first got it, but these days when I pull up to a red light and the car shuts off I find the sudden quiet to be calming. And really -- there are so many other things to get worked up about these days...

 

For future reference for folks reading this thread; the Ambulance Package does away with stop/start altogether. No button and no stopping. I think this is because an ambulance idles a lot here and there or needs all systems functioning in stop and go traffic.
I’m wondering if there is an idle timer from start up too. Haven’t tested that yet.

 

My local dealer told me that Ford will not allow them to use Forscan bypass the Auto Start/Stop function.

Is this true???

I would rather eliminate this function with the Forscan system than a more DIY route.

There is a simple fix to this. It costs about $90 and it makes the button behaves the way you want -- it remembers the last state. It's called Auto Start Stop Eliminator. I think there's a 10% promo code you can google. I have it in my 2020 Transit 148 HR van. It was easy to install (~10 minutes), and has worked perfectly ever since. Would buy again.

Cheers.

 

I used Forscan in my 2021 Transit Cargo to disable the Auto Stop/Start feature but it had no effect. When I experienced no change in behavior, I went back into Forscan to ensure that I had properly written the change and it was still set to disabled but no joy. Maybe there is an additional setting that also needs to be modified to make this work?

 

I disabled in my 2017 F150 with Forscan. I found lots of devices with a simple search.

I've seen this "feature" being discussed on other media sites. Question, I have a 2021 AWD NA 250 Transit and it does not have the Stop/Start. Is that an option ?

 

No, the standard 3.5 NA engine only came one way, without start/stop.

 

Any info on starter life with start stop? It just seems like a lot of extra stress on the starter, and how much fuel do you actually think this saves? I’m not sure it’s worth it🤷🏻‍♂️

 

I have a 2022 Frod transit Cargo Long and tall with the Ecoboost engine and have the AUX switches and the high spec connector. In the BEMM it states that pin # 24 is "Smart Regen Charge" and under comments says "SRC and start /stop inhibit when grounded". Does anyone know if grounding this wire will inhibit start/stop?
Thanks,
Todd
