Hey guys, moving up here from another section I frequent... Looking at a few F-150’s.

Quick question, and I apologize if it’s been asked a thousand times, but I didn’t see it in a quick search.

When did the start/stop technology system start on the F150? Did they all have it at the same time? All engines? I’m in Canada if that makes a difference.

While I’m here any known issues I should look at 2015 or above?

In particular I’m looking at CCSB 5.0 4x4 3.55’s XLT or above.

Thanks in adavance.
Jeff

 

The 5.0 gained it in 2018, easy to disable.

 

Thank you.

Havent even bought the truck... already looking up mods... lol.

 

Easiest mods are with forscan.

 

EDITED:
Just read up on forscan. And the sticky thread. I’ve heard of it, but never used it. I thought it was another monitor for diesels. Just spent a while reading up on it. Looks impressive. I had no idea you could do all of that.

thanks again.

 

Yeah I think for most vehicles that have start/stop, it's a button somewhere on the dash to disable it.
Neat feature on the Sport models (at least with the 2.7 Eco) - putting it in Sport mode automatically disables start/stop.

 

My daughters '15 2.7 had it and my '16 and '17 5.0's didn't. My new '20 3.0 PS came with it and was promptly and permanently disabled with a plug in module from Western Diesel. Possibly the worst ides Ford ever had for a turbocharged vehicle, especially a diesel. The small amount of fuel you may save won't pay for a replacement turbo.

 

Can you point me to a thread where auto stop start hurt a turbo?

 

Good point. Never thought of that. Wonder what temps those turbos are at in the diesels every time they shut down in city driving? Or the gas for that matter...

How do you like the 3.0?

Thanks for the input. Appreciate it.

 

Page 188 of the 2020 F150 owners manual specifically specifies a cool down period for the 3.0 diesel. The auto stop/start is just an attempt to bump the CAFE corporate mileage average. By the time you coke up the oil passages in a turbo to the point of failure your warranty is likely expired so no loss to the manufacturer. You can look up the test route that the EPA uses to determine mileage ratings and it is no way real world driving but would be very favorable to a vehicle with auto stop/start. GM tried turbos in the early 60's and the failure rate was so high they discontinued them after a couple of years.

 

You won't see turbo coking on a water cooled turbo like you would a oil cooled unit.

 

Don't need a thread....anybody with ANY mechanical aptitude that has been around for some years...knows this not a good idea.....engage me further I'm game....

 

The Auto Stop can be shut down in a number of ways.
The Simplest way is to get a $4, 4 pin trailer >>test<< plug with Led lamps and plug into the 4 pin Port and leave it there until you want to Tow..
On your dash display the guidelines and alarm will not be displayed or heard since the system thinks a trailer line is plugged in.
Otherwise, the rear camera display still works normal.
The Dash switch now has no effect on or off.
..
Another hint unrelated:
A battery plug-in tester display can show you when the Alternator is being addressed by the computer to charge the AGM Battery.
6 Leds, 3 battery voltage levels of Red, Yellow, and Green for voltage level..
3 , Red for Alternator malfunction, Green for normal and >>>> Yellow will light or flash when the computer is signalling the Alternator to charge the battery.
All this info is not included with the Monitor found at Harbor Freight. The one that looks like a rams head.
You may wonder how it works; it's the electronics in the monitor that make it possible to "sample" all the signals off the same single 12 volt line.
To boot, the system also senses temperature for functions but is not displayed.
If you know the system operation you can then see when the charge lamp works and under what conditions.
A surprising number of actions are controlled at various times.
It's all part of the engine performance, fuel mileage and battery long term life scheme..

 

I have a 2018 F150, and hate that feature. I wonder how long the starter will last.

 

I don't think any turbo temps get too high in city driving, not much boost required so the waste gate is pretty much full open. Temps will be at their highest when driving in hilly terrain or towing and that applies to both gas and diesel engines. So far the diesel is great. It doesn't have anywhere near the pep of a 5.0 but non-towing fuel cost per mile has gone from 11.7 cents/mile to 7.5 cents/mile with DEF factored in. 36% decrease in fuel cost will offset the $3000 extra cost of the engine in about 70K miles.
