Fellas...I'm goin crazy here and need some help. My main O2 Banks are getting different voltage readings, but my fuel trim for both banks look same. Bank 1 Primary O2 shows an average of only half the voltage reading as bank 2...the kicker is that they both increment at the same time/rate just at diff levels leaving me to believe they are working some what. What determines you air/fuel ratio, Fuel trim or primary O2 voltage readings? I am just trying to make sure I don't have an O2 sensor problem before getting a tune or my ECU adjusted for my mods. I don't want one bank to be running richer or leaner than the other before tuning. Does yall bank 1 and bank 2 primary O2's differ or does yall primary o2 voltage readings run neck and neck unlike mine? RB you might be able to tell with Cipher. Should I even be worried?

Thanks a million!
