Auto LSD question?

Alright, I have a question for anyone who knows a bit about Toyota's Auto LSD system. I don't really mess around with burnouts a lot but something I did today got me wondering. If you do a burnout with auto-lsd on will it leave two marks? Toyota says that it brakes the wheel that is spinning to direct power to the other wheel, so will it be doing this back and forth very fast if you do a burnout? The only reason I ask is that today I went to the beach, and on a dirt road I decided to have a little fun. Whenever I intentionally spin my wheels I do it with all systems: Auto LSD, Trac, and VSC completely off so its just like a normal open differential, and all I get are one wheel peels. But today on the dirt road I pushed the button once so Auto LSD was on, punched it and both wheels bit down hard into the dirt and I spun them for about 30 feet leaving two marks. Does this mean that it was using breaks back and forth so fast that it made two marks, or was it just because I was on dirt that both wheels were spinning?

 

The traction control just evens the resistance so both tires get the same power... instead of one tire (with less traction) doing all the spinning.

When I was testing my Tacoma's drive modes in the desert, doing 'burn-outs' on sandy roads... the AUTO LSD mode did create more even power distribution as I could create two 'rooster tails' of sand from the two rear tires. I posted that here on TW a couple years ago. I equated AUTO LSD to 'Posi-Traction', as in the film scene on 'My Cousin Vinny':

I wouldn't do wheel spinning unless all systems were off, it's not worth overheating/extra wear on the drum brakes (even if they last forever)...

 

Its a truck not a mustang.

 

Really?...

The point is that AUTO LSD is closer to a locked rear differential than TRAC for the effect of have both rear tires getting equal power... Because there isn't any engine regulation in AUTO LSD, you have full power to the tires. We have already read of TWers using AUTO LSD on boat ramps with success, when without it they cannot climb the ramp.

 

I hope they made him clean up that melted rubber!
