Slippery mode in 2H for rain?

[UncleBrad]

Finally it does not matter if you have a manual or a auto transmission, you get the same AWD 4A capability. The programming is tweaked of course for each application...

Thanks for the correction on torque vectoring. However, I'm not so sure that 4A is available on ANY manual transmission variant. Maybe I'm all wet. There are so few of these around; I've never seen another 2.3L/7MT besides my own. Can I get a confirmation, from say a well-optioned Badlands 2.3L/7MT?

My Bronco is a SASed (so with 'Advanced' 4A transfer case) Big Bend with the 2.3L and a manual. I even purchased it off a lot, did not have to special order it, so they exist, just not the usual dealer stock.

edit: I wanted the Badlands for the electric sway disconnect, but could not locate one so I ended up with this vehical. I had to add skids because they actually don't come with either the Big Bend or the Sasquatch package (!?), and I added Walker Links to my front sway bar in an attempt to get a bit extra articulation and not add a take off sway bar disconnect (quite the project if you look it up).

Interesting, so you believe it might brake an individual wheel while otherwise under positive torque, and not merely as a traction control (i.e. brake an individual wheel under neutral/negative torque distribution from drive-train)?

That said, part of the problem are these terms. The SAE actually does not officially define words like "AWD" & "Torque Vectoring", they are in reality squishy marketing terms. Still, in usual usage 'Torque Vectoring' refers to a system (either mechanically or brake based) that attemps to distribute torque "better" (again, variably defined) along the same axle under positive torque (i.e. under engine load in an accelerating situation), whereas as 'stability control' and its various sub species such as hill decent usually refers to a system that brakes an individual wheels under neutral/negative torque (i.e. not accelerating, putting power down, rather trying to control slippage and vehicle yaw).

In the end the modern software/computer controlled car is in a sense bleeding all this together, particuarly the modern EV as they can easily be designed/manufactured without the usual mechanical bits and pieces such as differentials, transfer cases, etc.

Well-stated.

I do not have a Trail Control-capable Bronco (7MT), but when at Off Roadeo, we did try it out, and the instructor was adamant that it looks at per-wheel speed (which, ok the Bronco does this all the time) and can adjust per-wheel (this is the main part of the claim, can it control per-wheel, and the only mechanical way the Bronco has to do this is via ABS/braking) to maintain traction while in use.

This was distinct from 4A, and did not require 4A (which only looks front-to-rear, not per-wheel).

We only tried it on a short portion of trail, it seemed to do ok, so not a big sample size or a lot of experience to validate the claim.

Excellent - thanks for the info. This thread has been really informative. Most of the dashboards around here have ducks on them...

What year? I didn’t know it was an option on a non-sas BD. It wasn’t the first couple years anyway.

2021!

Since the thread is off the rails anyway: I have a Bronco without front locker and since the traction control disengages in low range and isn't that impressive even in high range do you guys think using Trail Control might give me a poor man's locker through individual wheel control when needed? I've only used Trail Control a couple times, just for entertainment on short stretches.

Also the OM says to use Sand Mode when stuck, anybody know if it gets some enhanced Traction Control? Even in Low Range? I've never had the forethought to use it.

Yeah, suburban here, but I remember one time I watched this S10 make a left turn across 3 lanes of traffic when it had first started raining starting from a stop.

The guy clearly got on it just a bit too hard and he ended up spinning a 360 and going up over the median. Fortunately didn't hit anyone else and seemed like his truck was alright (especially given it was clearly a beater work truck already), but it looked like something you'd expect from an ice storm, not a hundredth of an inch of rain .

Happened to me many many years ago when I had an S10 Blazer with Uniroyal Tiger Paw tires. Was just starting to rain as I was coming through an intersection with a sweeping left turn. I don't think I even gave it any gas, and the truck spun me into a 180. Fortunately, there wasn't anyone around me and I stayed on the road.

Yeah, new rain can be slippery…broke my little finger…

I think if your considering anything on your bronco just because it’s raining your over thinking

your not accomplishing anything besides playing with buttons

I would think that - like driving on a snow covered surface - the use of lockers is not advised. Lockers can help you get out of mess when you DO slide off the road, but they also can contribute to your sliding off to begin with. Being easy on the throttle, road camber and surface type, vehicle wheelbase and weight distribution and of course tires are the biggest parameters.
