2006 Trac-off button?

I just recently purchased a 2006 IS350 with a track off button. I thought to turn off the traction in 2006 you had to do some sort of brake and foot brake pedal dance thing? Or have I been reading this wrong in the forums the whole time?

On 07+ models you can turn it off until you restart the car (or press the button again).

On an 06 everything turns back on above 30 mph if you just use the button.

On an 06 you need the pedal dance turn to them off until you restart the car.

I can't find the pedal dance info, and even if I did, I didn't understand it fully. How does it go?

So If I do PWR button, TRAC OFF button, that will be the quickest sprint to 60mph?

Nope. ECT-Pwr actually slows the car down for a full-throttle run. It's only really useful in part-throttle and on/off throttle driving.

Fastest 0-60 would be:

ECT-Normal
Track/VSC totally off (pedal dance on an 06, button on 07+)
Leave the shift lever in D, ignore the paddles.


If you're on stock/not great tires just floor it from a stop at this point.

If you're on good tires you might improve your times by brake-torquing to 1500-2k before slamming the gas pedal. (with stock tires you'll likely end up with some wheel spin doing this)

Whhhattt!? I have always used my ECT PWR button in my IS300 for quick sprints from 0-60 and I have always read that it holds on to each gear longer and redlining higher thus developing more power to the wheels?! I also notice when I use it in my 350 the car downshifts as a brake, something my 300 doesn't do. This has to be for overall more spirited driving, right?

I can't speak to its function on the IS300... but on the 2nd gen IS you hold gears the longest at WOT in Normal mode, not Power. This has been measured with datalogging and repeatedly folks get their best times at the drag strip in normal mode as a result.

For what ECT-Power DOES do on the 2IS see here:
Club Lexus Forums - View Single Post - Can I run with ECT Power mode continuosly?

As you can see it doesn't help at all when flooring it from a dead stop... and since it shifts at a lower rpm than Normal mode does it'll actually slow you down in a drag race type situation.
