Traction control off by default. Is this possible?
#2
I agree, but the traction control has saved me before (mainly in the rain) and I was able to kick the back end out easily on dry pavement (in an IS350) when I tried driving without the traction control right after I bought the car. There is an option to disable it for testing in Techstream.
UPDATE: Tried activating this inspection mode setting on my car and unfortunately it is not permanent. Looks like the best way to disable it is to hold down the TRAC button for 5 seconds while stopped (or do the "pedal dance" while in park on the 06 models). This is reset every time the car is turned off unfortunately. I think I remember reading about someone who wired a switch or relay to disable/enable TRAC/VSC on demand while in motion, but there weren't many details in the post.
I wouldn't recommend permanently disabling it since it would be very easy to fishtail into another car or spin out completely and crash while turning and/or acceleraring in the rain. If you swap in an ISF steering ECU and drive in PWR & D or PWR & S modes, the traction control is much less intrusive but still there to save you from hitting something.

Outside chance you ever leave your baby with a Valet or family member?
Be glad they have the TC on...at least initially!

with traction control on, sometimes it gets in your way and make you stuck on the steep driveway when you angle your lowered car with certain angle because 1 tire is hanging in the air and traction control kicks in and cuts off all power. Im sure some members with lowered car experiece this too.

The Lexus version is too conservative. I understand when your wheels are spinning from slippage but even when I try to put some throttle into it I can feel it kicking in. Turn it off and apply driving dynamics are much better. I feel I have more control of the car with it off. With it on you have no idea when it is going to kick in and makes for some dangerous situations.

As andper10 mentioned earlier, swapping the stock steering ECU for an IS-F Steering ECU (preferably one from 2011+) will not only significantly improve the steering feel and feedback but it will also allow the new option of setting the VDIM parameter to Sport (same as IS-F) which is much less intrusive than the ISx50 VDIM setting.
