Honestly, I don't know. If I was going to do this, I would do it properly with the SAP delete kit and DME flash tune which will turn it into an EU DME I believe. Theoretically, that will eliminate the CEL which should help pass smog. But then I read this FAQ and it's not guaranteed:

It's a toss up and I have a feeling mine will be going out soon (I have that type of luck).
Thanks, I hated going back in their twice but after reading the horror stories for track cars, I figured I would just tackle it.
