Auto LSD with VSC off over 30mph+ MOD???

Like the the title says I wanted to see if anyone has came up with a MOD to have auto LSD on while keeping the VSC from kicking in above 30mph? I have a 2010 Tacoma Sport pre-runner... An do frequent beach launches with my jet ski, and i'm getting tired of the VSC kicking in when trying to get some momentum/wheel spin to get outta the sand. Is there a mod to keep the auto LSD on without having the VSC kill my momentum?? Someone's gotta be able to help!! Ha

 

I don't have VSC luckily, but if I recall there is a way to cancel it with the buttons, holding it down or such.

 

That turns off the AUTO LSD too though , he wasnts AUTO LSD on without TRAC / VSC above 30 mph

 

What about... Would there be a way to trick the speed sensor or VSA to thinking your under 30mph all the time??

 

Do you realize that AUTO LSD (which is TRAC or traction control without engine regulation) is a LIMITED SLIP system, ie. so your low traction rear tire doesn't spin. It tries to share the power between the two rear tires, so they both rotate (or spin) at the same rate, instead of just one spinning and the other doing nothing (You ever see 'My Cousin Vinny'?). TRAC does this, but not with as much force as AUTO LSD as it also has engine regulation to slow the spin down from heavy pedal.

VSC is (mostly) an 'at highway speed' stability control to prevent you from spinning out of control when you make a sudden swerve to avoid something. VSC only works at low speed when you are making a turn on a slippery road and it corrects the over-steer (or rear slide out) that pickups deal with (low weight over drive axle).

 

Can you answer his question. I know you're the traction guy and all.

 

Yeah , he wants AUTO LSD without VSC / TRAC intervention above 30mph

 

10-4.

AUTO LSD is TRAC without any engine regulation, ie a stronger limited slip.

Toyota makes in confusing because they use the term 'TRAC OFF' to mean AUTO LSD ON !

'VSC OFF' is BOTH TRAC and VSC OFF... and of course no AUTO LSD either.

AUTO LSD works at any speed, but does prevent VSC from working (or controlling throttle) up to 30 MPH. VSC must come back on at that point.

What I don't get is the need to go over 30 mph on a boat launch ramp... so I am missing something the OP is after... ?

 

If you push the VSC button you get AUTO LSD on VSC / TRAC off

VSC / TRAC turns back on at 30mph

Push and hold turns AUTO LSD off and VSC off , does not come back on at 30 mph

Correct ?


He wants AUTO LSD on , VSC / TRAC off at all speeds

 

Well, that is hard, because here is what he wants:


"... An do frequent beach launches with my jet ski, and i'm getting tired of the VSC kicking in when trying to get some momentum/wheel spin to get outta the sand."

How in the world do you do 30 MPH launching jet skis on the beach...? Some momentum sounds like he might want to get over 5 mph... The answer is, he should have a 4WD to launch on a beach (unpaved ramp). In 2WD, the only way to improve his situation is to LOWER the tires' air pressure... I just don't get the 30 mph speed on a ramp, that's all...

 

Except in my year, it is still AUTO LSD over 30 mph... it doesn't change to TRAC.

Yes, push and hold turns off all and doesn't come back on at 30 mph, but WILL come back on to prevent a spin-out or roll over!

 

CLZay, what tires you have?
Just a thought, but going to an AT tire if you have an ASR might be the easy ticket, or even a bit wider tire.

 

I think we're both saying the same thing

He wants AUTO LSD on

He doesn't want VSC coming back on over 30mph

 

Sorry I not going over five miles an hour when exiting the sand, but my rear tires are spinning in access of 30+ sometimes and the VSC kicks in a limits this. I begin to slow an dig into the sand, so people say floor it and I am but the VSC isn't letting me get up top of the sand.. Just kinda frustrating seeing a lowered 2 wheel drive Chevy on 20's blast outta there better than me. An yes 4 wheel drive is what you need for beach launches, unless you have a locker and like to have fun

 

I'm running Nitto Terra Grappler 285 70 17, not a bad tire for the sand

 

Ok, so to say it correctly... is there a way to keep Auto LSD engaged at rear wheel speeds above 30mph without engine regulation to interrupt?

 

The tires do great when aired down, really soft an squishy but I still fight the engine regulation to have any fun at the dunes. But to each his own

 

I agree with you totally, just wanted to see if any of the techy people found a wire/mod to over ride or bypass the engine regulation

 

Have you tried turning off the VSC? (Stop moving truck, press and hold in the VSC button for a few seconds)

If traction is equal, even an open differential will split torque 50/50... and no power regulation.

The AUTO LSD has no regulation to 30 mph, and I don't think a spinning tire counts as speed? What the AUTO LSD does is brake ONE tire IF it spins more than another... so they are balanced. As said by another above, spinning tires don't move you... in sand, they just bury you. To stop spinning but not bog down from sand resistance, I only see lowering your air pressure as a solution.

Next Tacoma (or any model) should be a 4WD or at least an Off Road 2WD (locker) for what you do with your truck.

Good luck, hope the VSC OFF MODE works or air pressure trick works, and if you ever do find a way in AUTO LSD to prevent VSC from coming back on at 30 mph, let us know!

 

Yes I tried holding the button down while stopped, an just barried the tire even worst than with Auto LSD to the point I needed to get pulled out ha
