I would suggest updating the firmware on the AccessPORT - you may have an old version, especially if it is a used unit.
We were actually doing an open source with no Cobb just trying to re-tune for the elevation change from Rapid City SD to Crestview FL. He didn't give me an exact code, just told me that it was locked and had no way of altering any of my numbers. Although he could tell I was running lean under boost.
