It's great to hear no one is having any problems w/s1 & smog. DC just didn't want to spend a few extra bucks getting the cert.
I don't think anything in the s1 pcm has been "modified" since it is a whole new program, not a "modified" program. IMO, there wouldn't be any need to have both programs(stock & s1) on board with s1 since you have to buy a whole new unit and you would have your stock unit on stand by in a "just in case" situation...[:I]
