O2 sensor Error
 

Hi Guys, I just installed my RTEK Stage 2 in my car and it tells me that there is an error with the O2 sensor. My digital monitor shows AFR value and the logger shows nothing and has the above error. The WB02 is brand new so i don't think that it is the issue. I cut the ATP wire like the instructions state and attached the yellow cable which is the linear 0-5V line from the monitor. Calibrated per the WBO2 values. My car has the following: BNR Stage 2 Turbo and Racing Beat Full exhaust, nothing else engine performance wise. Any insight on the error would help.
Thanks!

The error it's giving you is about the stock o2 sensor, not your wideband. Did you remove the stock O2? and if so what did you do with the input? (Not this is separate from the linear output).
