AUTO LSD (or Not) for added traction in 2WD?

What did you expect? You are posting on a forum, people are going to have different opinions. You asked "Have you used AUTO LSD, and what did you discover?"

You might not like some people saying "I don't find it all that useful in my experience," but that's nothing wrong with that answer as each situation is different.

People like to debate you because you have this "I'm right, you are wrong... so shut the hell up" attitude on all your posts whether you explicitly say it or not.

You also seem to get very upset when someone says anything remotely negative about your "toys" even when they are using logic, reason, and laws of physics to point of possible weaknesses to traction control systems.

Someone pointing out a weakness is not the same as bashing it. It's like if someone says "Tacomas have worse departure angle than Jeeps," that's just a fact. It doesn't mean Tacomas aren't great on most other aspects or that they don't like Tacomas.

You cannot expend you mind on a subject unless you look at strenghts vs weaknesses, pros and cons. Why didn't you just call you thread "Say good things about AutoLSD and ATRAC!" Obviously that's all you wanted to hear.

 

Odd that you didn't find TRAC in H4 to be a miracle on sand they way I did? I always had to deflate my Tacos on that beach (dry sand part) until I took my '10 with TRAC. Just to see if it was a fluke of conditions... I turned the TRAC off (VSC OFF Mode) for open differentials in H4... and at 32 psi my Tacoma buried itself... This is where I got my first thrill with A-TRAC... Went into L4 and the A-TRAC drove my stuck Tacoma out... I then went back into H4 (TRAC ON) and continued to drive about.

I think you should try H4 (TRAC on) at 32 psi in the sand again... and then turn off the traction control and try the same thing in open differentials. If it works that well at 32 psi, then at lower pressure it should be even better?

 

Man, please don't make up stuff okay... I like you and you helped me in the beginning with my truck's features... also the title of this thread is: AUTO LSD (or Not) for added traction in 2WD? Not what you said it was.

I want to discuss peoples findings and their false notions.. but I have never said what they had sucks... never.

Peace.

 

ive tried both in loose sand and trac is def better. 4hi trac in sand still allows wheel spin and not throttle interuption and i dont think it locked up one tire fully like what somone else said

 

You are right it doesn't completely lock up slipping wheel... it uses pulsating motion using the ABS system.

 

See this is what I'm talking about. Find me something that I said about you saying "what they had sucks." Did you even read my post you just replied to? I was talking about your reaction to others saying TRAC/ALSD/ATRAC might not work well for some specific situation.

This is in your first post on this thread... the very last line to be exact:

thats ATRAC. trac is very smooth

 

Still pulsating motion using ABS though... TRAC is just quicker, super fast pauses of breaking rather than stronger less interval motion of ATRAC.

 

hmmm not on mine... mine is smooth and the brakes just grab harder and harder until sufficient traction is transfered. You can see right before the truck starts moving again the whell slows almost to a stop and the truck just goes

I see what you are saying, however what I'm saying is that TRAC never breaks it completely... it sends out ABS signal to pulsate. It's superquick pulses, you can kind of see it in your video when the wheel almost stopped. The fact that you have the ABS system means your breaks are going to pulsate when being used.

I agree that it's not like ATRAC where its breaks only like once every 3/4 of a turn of a wheel or so. When I say pulses I mean at ABS speed... you won't be able to see ABS pulse either but I assure you it does.

 

i see what your saying, i just meant that its smooth enough on sand to not cause you to dig in normally. I havent had any issues and trac has worked for me better than open/open in any terrain ive been in

the only reason itd activate is if you lose traction with open open. It works great for me.

 

No arguements here I agree completely about TRAC being awesome on sand and snow. I commented on your post to strengthen your point lol.

TRAC is far superior to open differentials in most situations. In fact, I can't imagine where not having TRAC would be beneficial. At worst, TRAC will have no benefit over open (all 4 wheels on ice for example)... but I can't think of a situation where having open diffs would be an advantage over TRAC.

Awesome looking truck BTW... single cabs actually look sweet with lifts and bigger tires.

 

thanks i have to update my avatar. i just finished my bumper

 

Exactly... sorry that we were not seeing the same things in our posts. The whole idea of posting on forums to to learn and be entertained... hopefully with good knowledge as an end result.

We all may have different interpretations of words and see typed words is far different than hearing them... I hope to continue a friendly exchange of ideas here.

trac in sand just always feels like its fighting my truck severely, and at speed when you have momentum open diff's don't matter cause your not spinning 2 wheel's.

and you don't need to fully stop a wheel in sand to make it dig in. only slow it down to a lower speed than what the car is doing. try letting off the throttle in deep sand and you'll sink even though your tires are still spinning.

airing down tires makes a huge difference in sand, but I never felt like I needed it.

on dirt, my alsd works really great, and I use it as my rain mode.


and abs can lock up your tire off road, it just pulsates high pressure really fast, so even if the tire does lock up, it unlocks immediately, giving you more turning control.

 

TRAC (H2 or H4) or AUTO LSD?

What kind of sand do you wheel in? The stuff in Baja on the beach I drive in requires deflating as it is just too loose/ soft/ bottomless, when dry.

Since this is a 2WD question thread, I presume that is what you are doing? AUTO LSD is unregulated torque applied to both tires in back.. and if one spins faster and begins to dig a hole, it is braked so the good tire can keep you moving.

Sand is a special animal... at least the kind I know! I like off roading in it because if you ever do get stuck... you just let air out (and clear away built up sand blocking your way) and you can drive on... always!

 

Snow/ mud...

Yesterday, wheeling with the SoCalTacomas I used AUTO LSD a lot more than I had before... instead of going right into H4 when traction was an issue.

We were climbing a slippery grade, and when there was some srtruggle to move, I pushed the button to activate AUTO LSD. I noticed an improvement right away... I imagine like what the Pre-Runners experience with a rear locker in 2WD. I keep it in H2/ AUTO LSD much longer than before under similar conditions and only went into 4WD when the mud was causing a lot of sliding. What is nice about AUTO LSD when you are under 30 mph, is that the VSC remains off so you don't get the annoying beep-beep-beep every times the rear fishtails.

 

Somehow I missed this thread, but it has some good information.

I'm going to try to revive it by asking for any more updates/uses everyone has had? It's been almost 2 years so I'm sure the AutoLSD has gotten more use!

 

Using AUTO LSD is the best you can do in a Prerunner unless you have an Offroad , then the locker is an asset
