2006-7 atrac update?

[TioChachie]

Hey everyone,
I have heard that the newer versions of atrac are a little bet better than what the Hundy got but then I noticed on slee's newbie guide to the 100 series that in 2006 there was an update to the brake assist functions on the truck including atrac. So do the 2006-7 models have a more modern version of atrac? I searched and slee was the only place I saw anything along those lines.

Pretty sure the only meaningful ATRAC updates are also associated with hardware differences, like the more precise (dual) sensors in the 05+ 4Runners.
Don't think there are any differences in ATRAC within the 100 series Cruisers.

I doubted there was a real difference between the earlier hundred series atrac and the 2006-7 models, but I figured it was worth looking into just in case it was another upgrade to consider when choosing between a 2005 and 2006-7.

Maybe most of the changes slee refers to, have more to day with VSC. Below is part of the info from Christo's web page:

"The Brake Control System was updated (ABS with EBD, Brake Assist, A-TRAC and VSC System)"
I would be interested if anyone else has input on the matter. Thanks
