Yes, that would be sweet. I'm not sold on the 'traction control via ABS' systems out there. Just last night George (SilverTank) and I were discussing his (bad) experience w/ a traction controlled Olds (I think he said it was an Olds) in heavy snow. It just isn't the same. My father's had a couple vehicles w/ 'traction control' now and none have been all that impressive, except his current Subi.. which is AWD too.
That ECTED unit sound pretty darn sweet..
