Well maybe I just heard some propaganda about Cobb removing the need for going through the required amount of "drive cycles" before marking the sensors ready.
A drive cycle is turn key on, drive @7-8 miles. turn key off.
I don't remember what the number needed to get the sensors in a ready state is.
Also this is not a Cobb specific thing, its in the stock ECU as well.
