I live in PA, and today I set my jb4 to map 0 because I was going in for an inspection and emission test. My friend that is a tech at bmw, texted me and said that the readiness codes were not ready and thought maybe I cleared it. So my question is, should I leave it on map 0 now, and drive it for a few days til the emission codes are ready for testing. Or should I leave it on map 3 like I have been? And also, when you switch from map 3 to 0, does that automatically clear all codes. I have no check engine lights or anything so what could be the problem. Any help or suggestions will be appereciated..thanks guys!
