'22 OBX 4A Binding issues... Need TSB

[Hemisfear]

The big issue is that I wanna launch it in Sport mode (4A) with the FP tune and the front tires get all squirrelly with torque steer instead of getting a good launch like a WRX or something.

With a tune...
There is nothing good about a WRX! lol

Only to be equaled by the number of posts regarding issues with their transfer case! lol
Why even have 2WD then?
Ford's position, really?
You are no more Ford than I am...
Ford are the ones who call it PART TIME?!
Again, show me something official, not an explanation of how it works, what is that supposed to bring to the discussion?

Something official? That was literally copied directly out of the workshop manual LOL

Feel free to continue acting like you know better then the information Ford puts out about its own product just because you were a "former dealership employee"
Not worth my time to continue arguing about something so obvious.

You are confusing full and part time systems, I am not familiar with billions of miles on this system!

So tell us, what are the mechanical differences (if any) between systems designated as "full" and "part time" by the various manufactures? Elaborate on how engineers and manufacturers design for the differences between such systems that leads to one being "part time" and other "full time" or "all wheel drive"?

The fact is neither you nor the creator of that video knows, all you have is emotion and assertions.

It is confusing to the average consumer granted, but then the average consumer does not have the technical/practical experience to understand the basic theory/operation of a differential, an axle, the when/how/what of 2/4 wheel drive, etc.

Again, there might be good (or bad) reason(s) to not leave your Bronco in 4A regularly, but neither you nor the creator of the video present them...

Respectfully Ducati, I really don't think "suitable for all conditions" means to use as a full time 4WD system, even my explanation could be interrupted as this!
I also watched a recent YouTube video which went into detail on this exact question, which I am trying to find for you.
Unless you have something more to show your position, as a former racing lead mechanic, former Ford dealership employee and lifelong 4x4'er, I vehemently stand by my opinion and I don't think telling people that it can be used in this manor is the responsible thing to do...

Sorry but your wrong. 4A runs in 2H 99% of the time and only engages 4wd when it senses it needs it. It's literally in the owners manual and numerous ford engineers who designed the system say the same.

Ignoring the disrespectful nature of your reply, you forgot former lead mechanic! lol
And as a current Ford Dealership employee, you should have already figured out that you have virtually no access to Ford corporate and are not capable of confirming any engineering aspects relating to Ford vehicles.
I will agree to disagree with no prejudice, sorry for wasting your valuable Bronco 6G forum time, I'm sure you have more advise to share!

(1) Intended use! lol
(2) The intended user is not the average consumer, the Bronco is a specialized vehicle, requiring a specialized mind! lol
(3) The creator of the video is a Ford Tech.
(4) If the people who are advising you to use the system full time can't offer you any guarantee, I wouldn't be listening, let them put their money where their mouth is...
(5) It's just my opinion, that's all, same with all of the others!
(6) If you are questioning the difference between full and part time 4WD systems, you are not knowledgeable enough to have this conversation, do some homework and come back!

I didn't realize Ford's engineering aspects were different from what they teach and inform their factory trained technicians. Afterall, they're the ones that need to know how things are designed to work to be repaired and diagnosed correctly. Seems very odd they would do that

Anyway, there was no disrespect. Sorry if you took it that way. I was just quoting what you called yourself as I don't know what dealership role you had. Have a good day.

Let us steer this thread in an productive direction. Pop quiz time:

1) How many differentials (in the technical sense) does a Bronco without 4A system have?
a) 1
b) 2
c) 3

2) How many differentials (in the technical sense) does a Bronco with 4A system have?
a) 1
b) 2
c) 3

3) A traditional 4x4 "transfer case" is a differential (i.e. it differentiates shaft speed and thus torque between two or more axles):
a) true
b) false

Getting these three questions right is sort of the minimum for having an opinion (at least one worth listening to) on the what/when of using the Bronco's 4A system.

I wonder if there is a way to poll answers

C, the answer is C. Any middle schooler flunking math knows that!

The big issue is that I wanna launch it in Sport mode (4A) with the FP tune and the front tires get all squirrelly with torque steer instead of getting a good launch like a WRX or something.

The WRX AWD system is a permanent mechanical 50/50 split so there's never a moment that the front or rear wheels aren't driven unlike the Bronco in 4A or many of today's AWD vehicles that are primary 2WD unless slippage is detected. A Golf R with the Haldex AWD system still kind of feels like a FWD vehicle because it is FWD most of the time as power only goes to the rear wheels when it's required so you can still get a little bit of torque steer at times. My old Model 3 Performance always had a bit of rear wheel slippage in slippery conditions as some of these electronic AWD systems simply aren't as quick to respond as mechanical systems. It seems Ford's 4A system has a slight enough delay in the power distribution that it's not putting enough power to the front wheels fast enough but I imagine launching quickly was not a major focus in the design stages.

Straight from the manual Mr. Smartass.

4A provides electronic control four-wheel drive with power delivered to all four wheels, as required, for increased traction. The information display will display 4A when this mode is selected. This mode is appropriate for all on-road driving conditions, such as dry road surfaces, wet pavement, snow, or gravel.


And I'm pretty sure I know more about this system then you considering i educated THREE dealerships worth of ford techs, because they didn't understand how the 4A system worked when I was trying to get my transfer case warrantied. Which they finally replaced under warranty because they had no idea how the system worked until a ford engineer came and showed them. I'm not surprised you're an ford tech on here acting like you know everything. I build 2000hp race cars and design advanced circutry for military applications. Word of advice, stop acting like a know it all because several people in this thread know way more than you do...

Yeah, I want Ford's 4A to act more like a permanent AWD when launching in Sport mode... not that every boring Tesla can't beat the Bronco to 60mph.
