I don't know if you have to, but I flashed back to stock then drove it like that for a week or two before taking it in for smog check.

I think you do have to drive around. I was under the impression that adaptations are automatically reset every time you flash a new map (stock or otherwise)

Do a search for "drive cycle" and you will see what you have to do to after changing maps and before smog check. Rather than do that I flashed to stock and left it like that for a week or two of normal driving instead.

Yea, a "drive cycle" was what I was referring to. If you're not in a hurry, normal driving accomplishes the same thing over time.

This is all good info. I'm leaning towards the MHD rather than the JB4.
