Default O2 CEL Code Chipped P28???? Why?

Ok im running a chipped P28 on a high compression LsV. The only CEL I have is an O2 sensor. This is tuned with crome, with O2's turned off. I tryed a chipped P75 and a chipped P28 that I had layin around and i have the same code with all of the ECUs. Reflashed chip and tried using the ostrage, resulting in the same CEL O2 code #1.....What the hell? And suggestions?
