Yes it's an open diff. aka (pegleg)

 

To my understanding Ford has designed the traction control system to work in such a way that it acts like LSD (When the lockers not engaged).

Here's some video's demonstrating.

Spin Control pt 1.mp4 - YouTube

Spin Control pt 2.mp4 - YouTube

 

Here we are back to page 1 again. lol
On gravel my spin control works just like it does in the video. On pavement when I loose traction taking off in a spirited manner I get the 1 wheel peel, for now anyway. I'm going to cure that when I get a Detroit TrueTrac L/S carrier.

 

Did you watch all of video #2? He performs a ''spirited'' acceleration with one tire in the dirt and one on the pavement in which both tires still spun. I'm not saying that Fords spin control is a LS diff...But its obviously been programed to ''imitate'' the dutys of a LS diff.

Doesn't really matter to me either way...Back Feb we had a good snow storm and my FX4 seemed to do just fine in 2WD. There were only a few occasions that I felt a need for 4WD...Much less 4WD with a locked rear end.

 

i think the difference may be the vigor with which one gets after the truck.

in the videos he is imparting FAR more wheel spin and throttle input that I would consider "reasonable"

it makes for a good demonstration, but in the real world, especially when in snow, if you were to get after the truck like that, 1WSC, Locker, LS, makes no difference .... you'd be STUCK cauz you don't know how to drive.

the goal off road is to NOT spin wheels, except in some extreme isolated circumstances.

ford's 1WSC works well with extreme throttle inputs, but i have not seen any videos that show how well it works when you are just barely breaking loose, but still stuck none-the-less.

i'm talking about "backing a trailer up a wet grassy hill" type situation .... LS, Locker, or 4WD is about the only thing that is going to get you there. If you rely on the 1WSC, your boat is going to smash through the other side of the building if you ever hook it up. And i don't care what you say ... you spin wheels on wet grass, and you are SCREWED .... you need a good LS or 4WD to PREVENT wheel spin ... not a 1WSC to mitigate it.

my only complaint with the E-locker, is it should be part of the TC system, where it engages automatically after about 1/2 wheel rotation,

 

Yes I've seen that demonstration. My gripe with the SC system it only works in some conditions. When both tires are on pavement mine only does the 1 wheel peel for 15'-20' then the TC stops the spinning.

Also that is with a lot of throttle input (probably what meborder refers to as more than a reasonable amount). Because it's a lot harder to spin 34's (or a 34 lol) on pavement than it is on gravel.

 

I personally do not like the E-locker from the factory. The less control the PCM has is sometimes a good thing. Normally, I would not need 4wd or L/S. But they are essential for me to get the car trailer out of the back yard. If I don't use 4 wheel low range I'm going to tear the hell out of the grass. With 4wd low range I can just back the trailer out of the yard nice and easy without tearing up the yard. I have also had to park the trailer at some car shows that 4wd low has really saved my butt. I like having more control over driving than just steering, braking, or pressing on the throttle pedal. These new vehicles are causing the general public to never develop good driving skills by making the PCM have too much control.

 

What he was saying is that I posts these two videos on page one of this thread!

 

Lol that'll teach me to read back instead of just reading the last page haha.

 

the pcm does not control the e-locker, except to disengage it at a preset speed, and at extreme steering angles.

i thing it should, but still have driver interface. Perhaps there are those that would wish to disable the e-locker, but i've never found a low traction situation where i would not want both rear wheels locked in. (perhaps while turning on your yard, i would want it unlocked but when driving straight, i would always lock it).

... i would ask the question ... are they keeping drivers from developing good skills, or are they just preventing the accident they would have caused because they never would develop good skills?

my gripe is the cost of the vehicle systems ... but i'm not sure what is cheaper ... my insurance rates going up on the whole, or the cost of the systems that keep these people out of wrecks?

 

if you want to use the 1WSC only, you need to disable the TC system.

your gripe and mine is the same. the TC system will always shut down wheel spin before the 1WSC engages.

at least on the 11's you retain the 1WSC when you shut off the TC. the 9's and 10's disable both when you hit the button.

 

I still maintain if it ain't broke, don't fix it. Traction Control, E-locker, TP monitors, oil change minders. I don't need them nor do I want them. I resent being required to pay for them and resent being forced to pay the extra expense for service when there is a problem on one of the systems. The old LS, oil change sticker on the corner of the windshield, throttle control skill, and a tire gauge along with visual inspection have never let me down yet. Have we as a society gotten so lazy that we must rely on all the electronic do-dads so heavily? No wonder these trucks are so over-priced. I wish at least Ford and the government would give us a choice instead of shoving these things down our throats.

 

I look at it as a convenience and a safety aspect. It is nice to have the traction control especially in those instances of sudden loss of traction.

 

Prince, I've experienced sudden loss of traction a few times over the years, and it really isn't that hard to lift the throttle foot for an instant. On a rwd that will do just as well as traction control and doesn't cost anything to install or maintain and repair (free). There is a point of diminishing returns on convenience. For those who want it and are willing to pay for it, that's cool. I would consider that convenience a luxury. But there are many of us who are not willing to pay for it and consider it a major inconvenience and unnecessary expense when it needs repair or service. It has crossed the threshold of diminishing returns to the point that it isn't worth the expense and inconvenience for me and many others like me.

 

to ask the same question a different way:

would you prefer that the driver about to cross centerline had TC, and Stability control, or would you prefer that they didnt?

don't get me wrong, i'm not in favor of the added expense, especially when mandated by government. .... but the fact is that TC systems can out perform any driver because they can do things that the driver cannot.

i had a friend tell me that the stability control saved him from wrecking his vehicle as he drove up on a bridge that was unexpectedly icy ... his exact words were "i tried everything i could to save it, and if i could have hit the brakes on the left side of the vehicle, i would have .. but that's what the stability control did and it saved me from hitting the barrier" .... he's a pretty good driver, to be honest ... (apparently not good enough to see that the bridge could have been icy, but we all have off days)

oncoming traffic was glad that he had stability control ...

understand that insurance companies have played a big part in this government mandate. wrecks cost money, and if you give people the choice, many will opt not to purchase the additional saftey. but it is easy to sell saftey, and convince the government to mandate it.

just for giggles ... to a search for the Manual on Uniform Traffic Control Devices (MUTCD) .... this is my world, you wanna talk about government mandates!

off topic .... sorry ....

YEEEAH LOCKERS!!!! or BOOOO LOCKERS!!!! i forgot where i stand ....
