I may be wrong but as I understand it, it really only comes into play during cold starts in the first few minutes of operation.

In any case, mine's been disconnected since I bought it. Austin just recently added a smog inspection and my MB indy said I'd need it if I had my car inspected in Austin. However, I live in Wimberley, a small town in the area and there are no such requirements here. The car just passed inspection this morning.
