VDIM Disabilization

Hey I found this on a website. Never heard of it before:
Some people may already know this, so it may be useless to them...

IS350/IS250 VDIM Cheat Code

The vehicle dynamics integrated management (VDIM) system automatically prevents excess wheel spin and fishtailing. If you deactivate the system by pushing the dash button, the system automatically comes back on after exceeding 30 mph. The overly protective Toyota designers probably did this to reduce our insuance rates, but it's just no fun. If Toyota wants to really compete with BMW, then it needs to allow drivers to make more decisions and assume the risks of driving.

If you wish to temporarily disable the VDIM completely, Toyota programmed a work-around. This "cheat code" will disable the VDIM until the car is truned off.

1. Start the car with the parking brake on.

2. Keeping the parking brake on, push (or tap) the foot brake twice

3. Keeping the foot brake down, push (or tap) the parking brake twice

4. Repeat untill the sliding car warning light appears on the dash

Normally, only two cycles (foot - parking - foot - parking) are required. With practice, you can disable the VDIM in under 4 seconds.

Or you can just hold the TRAC button on the dash down for a few seconds. That works pretty well too on 07+ models

(the trick you posted is only required on 2006 models, and has been known for years)

Hey Knightshade, do you know if shift-times w/ tiptronic is faster than the paddles?

The best shifts (from a dead stop, at wide-open-throttle) will be if you leave the car in D, and leave the ECT button in normal mode.

The paddles and the stick don't actually shift the car, they only select the highest gear the car is allowed to use. The transmission always shifts automatically on its own based on what the computer tells it to do, even if the paddles can fool you into thinking you're doing something about it.

If you'd like proof there's no direct shifting go ahead and start from a dead stop in S mode with 4 on the dash. Now switch the multi-display to showing you the -actual- gear you're in... it'll be 1. It'll shift on its own through 2, 3, and 4 as the ECU dictates, only stopping at 4 because that's the highest-allowed-gear you selected.

For that matter, start the same way, with S-4, and displaying real gear in use... now very slowly push the gas... at 10 mph, hit the downshift on the stick or paddle... the S indicator will switch to 3, but the car won't shift at all, because at 10 mph you weren't in 4th anyway, you were likely in 1 or 2, which is below the max allowed gear of 3 anyway.

So anyone know how trackable this is? I'm still trying to figure out how much of the dash/disable cheat will void your warranty when you go in with transmission problems. Does the ECU log changes to the stability system like these?

Turning off the VSC/TRAC with the dash button, on 07+ models, is explicitly explained in the owners manual- it absolutely should have 0 impact on warranty claims regardless of being logged or not since the owners manual instructs you in how to do it.

Why would it be any different? Why would Lexus enable this mode if it weren't meant to be used by the owner?

Sorry to go off topic, but what im getting from many posts is that just driving the car in D, and turning the traction control off, is the fastest way to go. From peoples experience, what is the most ideal launch RPM? does holding the brake and gas compromise my driveline or transmission? I read in the car manual, to not hold the brake and gas at the same time?

If you know how to launch with minimum tire spin, perhaps.
