I agree 100% with you. I purchased brand new blizzaks this season and the moment i slip the traction turns on. It then slows me down, THEN it gets me stuck. The traction is so damn sensitive. Compared to my gone E60, the traction control system in the is350 has many many many many flaws.

VDIM on the F is a lot better, but still far from perfect. At least it's world's better than the TRAC they sold on the Supra. That system was controlled by an evil-hearted demon with a death wish for the driver.

Probably true because it does not have true LSD so it ends up cutting off the power too rite? So if one tire loses grip, the other tire that still has grip does not spin up and engine would cut the power. If it were true LSD, then the tire which still has grip would spin up.

If you use delicate brake/gas pedal play, such that you can make both wheels spin up at about the same rotation speed without making the system think there is a slip esentially, tricking the system there is grip and would be able make the car move without having the engine cut out.

It's a lot easier to engage the parking brake a few clicks...it does what you need a LOT better than braking on all four wheels especially in low traction environments.

I used this trick at Bellows AFS on the east side of Oahu when my friend got her 200SX stuck in the beach sand...it drove right out with the parking brake on three clicks!

And as for ECT Snow, i found it to be pretty useless. I drove for 3 hours last night in the snow in MA and played around with that, and was able to control my 250 a lot more while the car wasn't in ECT snow mode. Just drive with a little common sense and if you want some snow tires and you should be set.
Granted I don't have the 350 but I agree with the above my is250 without snow mode and traction control off is much easier to drive in the snow than with it on

Oh I never thought of it that way. Just the gas/pedal play requires some feathering of either pedal to make things work out.

Good alternative with the parking brakes.

I'm actually okay with it since this is the first car I ever drove or owned in the snow. Although I do hate the traction control system even though it's for my own benefit. A few weeks ago, I was trying to do a left turn before the light was about to turn orange. There's was only 2 inches of un-plowed snow on the street and my rear wheels slipped. Traction control went on and I stopped diagonally right in the center of the streets and the lights turned on me. It was embarrassing cause there was a Ford F250 and a Chevy Tahoe waiting for me to get out of the intersection while they had no problems in the snow.

I also got Bridgestone Blizzak LM-25s but these seem pretty useless but better than the Potenzas' that my neighbor had on his '06 IS350. He took almost 5 minutes trying to get out of his parking spot with only 3 inches of snow. Felt bad for him cause he doesn't have the switch to turn off traction control which is how I got out of the snow sometimes. The rear wheels are too wide as well.

You ought to point him to the FAQ for our forum, where he can learn to turn off traction control on his '06 off with the pedal dance. You should also point him to the tire dealer, so that he can buy a set of winter tires.

You don't need the pedal dance to turn off TRAC on an '06. You need the pedal dance to turn off VSC. TRAC can be turned off with the switch just like any other 2IS. You just can't hold the switch down and have VSC turn off and stay off. TRAC will also automatically turn back on as soon as wheel speed exceeds 30 mph on the '06.
