22-24 Steering Softened? anybody? Forscan setting?

[Fastcar]

Having driven several '25's - including the Tremor, I love they way they drive - but I'm with you %1000 on the logistics issues with the re-design (the split tailgate,,, loading gear would be a backbreaker, plus we have 2 big dogs that need to jump in the back that would now not be able to - plus the squircle wheel that would require relearning the basics of parking lot maneuvering - and the lack of buttons, most of all the external lighting controls!!)

These issues aside, the big glaring question for me mechanically is the ELSD... i made the same assumption about it having the ELSD just like the Gen4's.,,, however my concern is that the official specifications from Ford, + the actual window stickers specifically list "3.73 E-locker" now, but the Gen4 stickers specifically listed ELSD. @LokiWolf any recon here?

They sure don't make it easy.

In my mind, Electronic Limited Slip Differential, like my 2024 Limited has, and Electronic Locking Differential, like the 2025 Tremor has, are two different things. Ford's wording is clear to me.

 

[LokiWolf]

If you got 4A mode, you also got a differential between front and rear too. When you turn the steering wheel left or right it open up the differential some to allow to go through corners without drive train binding.

The transfer case has ALWAYS been clutch based in the Expedition, and it has always used wheel speed sensors to affect those clutches so there can be slip front to rear in 4A and to vary the torque to the front when needed, but that has very little to do with turning. The front and rear diff's handle the speed differential between inside and outside wheels during turning, not the Transfer case.

Correct, and they are consistent in the wording EVERYWHERE, including the printed materials(PDF), and the manual.

Everything I see about anything other than the Tremor mentions Non-Limited Slip.

The Window stickers for 2026 SPP's mention the HO motor(Tune Only FYI, no internal differences), and nothing about LSD, yet alone ELSD.

The Tremor Stickers mention E-Locker, so the ELD. Basically the same thing in any F150. It is a pin lock, not clutch, and same speed left and right when engaged.

So my assessment from over a year ago stands, the ELSD is gone with regards to the 25+. The ELD is in the Tremor(More off road focused).

@bb37 + @LokiWolf / thanks for confirming what I understood to be the case / i think i'll stay with the plan for a leftover '24 all things considered....

@LokiWolf : back to the OP Q i had.... do you know / have you encountered if the Forscan for '22 - '24 has setting adjustments for the PSCM settings (ie: sport / normal etc) like the F150's have? my current model is '19 so i haven't had the chance to dig in...

I would need to plug in to a 24. Based on other similarities, I would bet the PSCM on a 24 mirrors a 23 F150. But I can't confirm that. Racking my brain to see if I can get access to 24 Expedition in the near future.

thank you sir / if i end up with one sooner than later i’ll pop back in here with the results /

Anything I can help with remotely since I have a 2024 Limited 304A?

Yes! if you have FORSCAN, can you get me a save of the whole PSCM Module! I can compare, cross reference to a 2023 F150, and that should answer the questions we need.

@bb37 + @LokiWolf i appreciate the heck outta y'all.

I have both a '20 Expedition MAX 4x4 and a '22 F150 4x4. I drive them both often. Sometimes back to back, same routes, same garages, etc. There is a huge difference in the steering effort at all speeds under all conditions between the two, with the '20 Expedition being much higher effort (which I personally prefer). The 2 trucks now have identical rubber, identical inflation, very nearly identical alignment (I've checked/adjusted it myself - they were both delivered toed "out" within specs and I adjusted them to be toed "in" near the specification limit.) Additionally, they share many front suspension parts and basic geometry.

The higher effort with the Expedition is apparent when the vehicle is stopped, as well as when it's moving; this leads me to believe that the ELSD is not the primary reason for the difference in effort (though when in motion anything that resists rear wheel speed differentials such as limited slip or programmed braking could certainly affect steering effort). This leaves only the programmed effort supplied by the electric assist to be the difference.

My '20 Expedition has the rudimentary lane departure system of the day. The '22 F150 is one step below Blue Cruise; so, it virtually steers itself whenever road lines are available, brakes for traffic, etc. I can only speculate that the decision on both steering efforts and ratios chosen in these vehicles is influenced by the lane departure/self-driving features.

Personally, I feel our 2019 Exp Limited's steering is TOO heavy, especially when you use LKA. You almost have to allow LKA to pre-steer for you, and allow it to take some effort off the wheel.

I wonder if there's a way to upgrade to 22 LKA software.

for road condtions, my wife's Mercedes 4Matic Wagon has full time AWD that is, I think, 70-30 or 60-40 rear-front loaded, and is the most incredibly well planted car I've ever driven on all sorts of mostly paved surfaces. There's no selection of fancy modes, its always AWD, although I *think* you can turn off ESC (electronic stability control) but we never have. You can be hauling butt around a narrow twisty mountain lane and hit a pile of wet leaves and there's no drama. nail the brakes really hard cuz some idjit jumps in front of you at half your speed, no drama.

Then we put Michelin CrossClimate2 tires on it, oh yeah! Incredible in heavy rains.... she had to navigate a steep driveway near Lake Tahoe with 4" of fresh snow and ice, and it just drove right up it like it was dry pavement (previously it had Michelin Pilot Sport AS4 which were pretty damn good).

A NURD, indeed!

If you have a 4x4 Expedition, then it's indeed full time four wheel drive. As I understand it, it's 2 wheel drive mode is simply the front axles disengaged through some electronics/vacuum if I recall correctly.

I agree, AWD is excellent as well. I have it on my Lexus LS460 AWD, with interestingly enough Michelin Pilot Sport AS4's. Those tires seem ok for light snow, but I honestly haven't driven the car in deeper snow enough to tell (only have had the car for 2 years now). Thinking about getting a set of 4 wheels, and mounting dedicated snow tires for winter. I have snow tires/wheel that fit my 2004 Solara V6 and ES330, and while still 50% tread left, they're from 2011. Luckily they are still pretty soft and aren't cracking yet. But I think I want to use my AWD car for winter going forward.

While I am unsure of how to hack it, whether forscan could be used or not, there should be a way to "program" the effort. My 2012 GT500 has programmable steering effort. I currently have it adjusted to the "variable" effort mode where the effort increases with velocity. It took a little getting used to when accelerating around clover leaves. But, overall is very practical. Very low effort in parking lots and very high effort at 3 digit speeds. If they had the technology and foresight to offer it in 2012, why won't the undesirables in Product Development provide it in all products, it's just software?

There must be someone who has figured out how to hack it.
