I tried to search and could not come up with a definitive answer. I found these threads which were quite useful:

https://www.clublexus.com/forums/is-...vdim-work.html

So my questions:
What ECU's do our cars have? VDIM, Steering, Main, anything else?
All ECU's plug and play, interchangable between all years? Benefits of ISF ecu's if plug and play?
I want the 07+ Traction off 3 second hold vs my 06 pedal dance, is it possible?

I'm looking for specific info on my 06, and interchangability between all 2IS.

Thanks

 

Anyone have any info?

 

you can buy the 07+ IS skid computer to get rid of the pedal dance. I dont know the part numbers so make sure you get the one thats 07+

You can also swap in 2011+ ISF steering computers to improve the steering feel. You have to get those calibrated with a Techstream

 

The 07+ skid control is part# 89540-53290 and will have a VT on the label... It is located under the glove box, simply remove the access panel to get to it, and it is held in place by 3 bolts. Very simple install... I will caution you that if you install it(in an 06), when you disengage traction control via the button you will get a warning message in the display screen that says "vsc test mode" and the red triangle with exclamation point. I have not been able to find out if the dealer can remove this warning.

Here is one for sale on ebay:
