VDIM fundamentals -- Think you know??
Ouch.
(Enough said)
Too rich for my blood but thanks Lobux for taking the time and effort to find the answer. Now we know however that it can be done.
Out of curiousity, any other benefits of installing a 2007 ECU? And would an ECU from a junked IS350 be feasible (and cheaper hopefully)?

It takes about 5 minutes to do the swap if you work slowly. You only need a 10mm socket on a short extension to remove the three screws holding in the skid control ECU. Everything else snaps apart/together.
The new ECU lists for $1492.94. It actually costs more than the engine ECM.

No other known benefits. Yes, the ECU from an irreparable total would be fine. It is extremely unlikely this ECU would ever be damaged in an accident, unless the passenger's knee airbag were to cause the support to smash into the ECU, but from the positioning, it looks pretty unlikely.
Most of the dismantlers I know charge half of MSRP for ECUs.

Thanks Lobux. You definitely provided some great information in this thread. I'll keep this post in mind. hehe
BTW, I thought seriously about doing 18's in the front, and 19's in the rear. It shouldn't give VDIM any problems at all since the OEM rear tires are already 1" taller than the OEM fronts. If you get the right tire sizes, that 1" difference in height could be entirely wheel, instead of rediculously tall sidewalls like the OEM rear tires have.

The car will not beep at you constantly no matter how staggered your setup is. The beeping that you hear has nothing to do with traction control. You will only hear the beep when the car enters a skid, period. Simply, if you hear the beep, the car is not traveling in the direction its pointed. The VSC computer is able to detect a skid because it receives a signal from the yaw-rate sensor which is located in the exact center of the vehicle. There's no way you will ever hear the beep unless the car is over/under-steering.

I got a question for anyone who thinks they can answer a very technical problem.. . I know for the 07 2IS u can turn VDIM (traction control??) on/off with a switch. Which would make this conversion so much easier. However I was badass enough to get a 2IS in 05 (yea right...)... which means i got the 06 version. Heres where i need some help.. I was thinking to myself.. Damm i wanna be ganster and run 19x9's in the front and 20's x10.5 in the rear.. If the tire rotation of the front wheels differes from that of the rear wheels; will it cause the traction control to constantly beep at me like when your tires slip (since its registering as different rotation ratio's)? The left and right sides will be in sync.. just not the front and rear.. So I guess my question is where VDIM takes it's measurements.. From the front tires vs. the rear tires?? or if the rear left tire differs from the rear right tire?? Any technical advise would be greatefully appreciated. Thanks --
If you're familiar with a bicycle speed sensor (magnet attached to spoke, rotates around and triggers a sensor on the stay) I believe it acts sort of like that. But the TPM senser acts as the magnet (or vice versa) and there is a stationary sensor inside the wheel well. If you increase the diameter of your wheels but still have the TPM sensor installed VDIM will accommodate since the diameter of the wheel and speed of rotation is used to calculate speed.
Of course, this is pure speculation but I thought I remembered reading something about a sensor mounted underneath by the wheel well when perusing the techinfo.toyota.com documents.

However, that still doesn't change the fact that extreme changes in outer tire diameter will effect VDIM.

I would love to be enlightened as to how to perform the infamous pedal dance. I have never heard of it and the biggest complaint I have with my 06 IS350 is the fact that I can't get the car to drift. Educate me, someone, anyone, help me get sideways.
