Bucknasty11 3.7

I've been considering this for a while, probably will do it eventually. I have the open rear right now, so I really want to improve that. That was the only thing I wanted in my truck when I bought it that it didn't have. Glad your liking it so far, keep us updated. I know I will be interested.

Same here, 3.31 open diff

We had some wind, so I took off today, cut up some broken branches, put the snow tires on the wifes Sienna, and then I went and wasted a little $3.60 fuel -

I went to a off road place, and tried a little dirt/gravel climbing -

First, with traction control turned off - 2WD - and it climbed, bounced, dug it's way right up it -

Turned the traction control back on, did the same thing, and it performed the same, but with a few flashes as the traction control was applying brake I assume.

I might not understand TC correctly - as I thought that if one wheel started spinning faster than the other that it would apply a little brake to the spinning wheel, and then the open carrier would push the torque to the other wheel.

Correct me if I'm wrong please -

So, let's say I get a wheel spinning in the air - in theory the TC should kick my True-trac in the butt, by hitting that brake, and it should lock up and push me out ?

If that's the case, I see no reason to turn the TC off -

Any other thoughts ?

I can add this after having them on my f250 for 6 years. If you run into problems off road just give it a little brake and it will Lock up for you, i.e. boat ramps, hunting roads etc.

So do you leave the TC off, or on ?

I'd rather have a L/S than an open differential on the street. Unfortunately it wasn't an option on the FX4.

the traction control and the antispin (a/s) are 2 TOTALLY different systems.
I find that the trac and a/s actually kinda work against each other. the trac only backs the throttle off to help gain traction back. the A/S uses the brakes to transfer power from one side to the other. I have found that the a/s actually works BETTER when the trac is turned off.
I park in the grass at my house and I have a slight incline in my yard. when its wet with trac on I get A LOT of 1-wheel action, at times it wont even move, just sits and spins. but turn it off and it does much better. there have been times where I start spinning and cant move, reach over press the button and try to go again and it just takes off. the ABS pump makes all kinds of racket but it works well.
its not well enough to completely replace a l/s rear, but well enough that I think I will be just fine in the snow this year.

The above post is correct.

The traction control blips the throttle when it senses wheel slip to keep you on the road, but that will sick you in the mud, sand, or snow. Turn it off by holding down the button for five seconds.

The two wheel antislip is independent, and cannot be turned off. They changed the system for 2012s, ad they mastered the technology.

I can attest that it extremely effective at redirecting torque, and it does it quicker than you can sense one wheel slip. This week, I have been playing in some mud holes on the way home from work, and my confidence is now that I think Ford has eliminated the need for a physical limited slip pack, and eliminated the need for a locker in all but the most extreme circumstances.

So I have tested this system in both deep sand, and now, several tires of mud, and done decent depth. I stopped in the middle of a good little bog, then stood on it, and all four tires threw mud.

By the way, the stock Michelin AT2S are better than the BFG s, and Cooper ATRs that I have previously ran.

The tires likely have more to do with the trouble the above poster is encountering that the system, and with some more grippy rubber, he'd find this system better than the LS diff. I never understood why Ford puts those crappy Pirelli tires on our trucks.

With the traction control turned off, it's nearly impossible to stick these trucks, unless you get high centered.

My spin control works great on dirt, grass, mud and snow (on surfaces where it's easy to loose traction). It kicks on instantly and acts just like a L/S. But on pavement it does nothing. On pavement I get the one wheel peel with TC on or off. It makes it hard when you don't have much time to merge into traffic and your spinning one tire and not getting anywhere.

I've seen you say that before. That would **** me off!

I think that's one of the things Ford fixed for the 2012s, because, with the traction control off, I can leave two very, very long black stripes.
