NGK AFX problems

I have a NGK AFX wideband, I connected the analog output wire to the ecu. It reads the wideband but the numbers are way wrong. I clipped the resistors on the board, I don't remember the numbers of my head. So, no matter what voltage I put in to compensate it's still wrong. The numbers go rich when it's lean and lean when it's rich.

Almost a month, anyone know anything?

<shrug> My AFX works fine, as expected. I'd suggest rechecking your wiring, especially the grounds, and confirm the AFX output using a VOM.
