whats the vdim cheat w/ traction control thing
I was reading about this in an IS350 thread about how they do this before they race to get more power. Can you do it on the sc?

I don't think the SC has VDIM, does it? Only the 06 GS and IS do?
Edit - checked the Lexus website to confirm... SC has the VSC traction control system for now, it's sure to show up in the next revision. Can't turn off what isn't there

dave is correct, no vdim on the sc430 at all, just the 06 gs and is right now
and to disable your vsc? sure, just press on the vsc off button on the center contorl (right by the arm rest) and you are good to go
and no it won't give you more power, it just don't take away power when you are losing control. just make sur eyou know what you are doing

When you're close to launch time 'power brake' a little by holding your foot on the gas and the other on the brake and while you're holding the car still bring the RPMs up to about 2000 - 2200 before letting it go and smashing accellerator down. If you hold the power brake too long it heats up the transmission / torque converter so I don't recommend anyone do that often.
thanks dave.
I thought that by putting it in 4 instead of D then you rev higher per gear is this wrong logic? Can someone correct me or give me the reason to put it in D

there shouldn't be any difference by putting it in 4 or D. it simply means that 4 will utilize upto 4 gears and D will utilize upto all 5 gears. One other ways to mess up your car to have quick launch is to put it in "N" reve up to 2000 rpm and then put it in D at the launch.

are you sure about that. The shift patterns seem to be different as well. My car seems much faster in 4 than D. It is also much more resposive. The only time I drive in "D" is the highway and not always than either.

I wouldn't reccomend dropping the car into D at 2000rpm. Powerbraking is a better option, though it will heat up your trans fluid if you do it too long, (IMO) it's a lot better than slamming it into gear.
And as others've said, leaving it in 4 should take out the 5th gear/Overdrive and give you a snappier response. W/O knowing the exact ratios and OD on the SC, you'll likely benefit in 2nd gear on.

That was my assumption when I thought leaving it in 4th gear would be better. I thought D or overdrive just made the gear ratios longer to save more gas.

i have tried both in my gs400 and sc430. putting it in d or 4, you floor it, it's the same throughout the first 3 gears
