what causes this? I made a post a few days ago about not having a vacuum line going to the stock FPR just to the vortech, which I found out I need to do. Could this be a related problem, or is my o2 sensor fucked.

I have the autometer air/fuel gauge saying it's reading more than 1 volt and the apex turbo timer telling me it's reading more than one volt, and there both getting info from different sources(o2 sensor and ECU, respectively)

It did this with the o2 sensor that came with the motor, so I swapped the o2 for the one off my stock motor and now it's doing it still...

thanks...

Not quite sure I understand how your turbo timer is reading a/f but more than 1.0 volt is rich as ****.

the apex tt can read a/f, so does that mean my o2 sensor is working just reading way to much fuel?

You can tell it's working if when the engine is warm and you are cruising, off boost, high vacuum, the voltage fluctuates from greater than 0.5 volts to less than 0.5 volts, although the fluctuation will be rapid so you may just be able to see that it's centered around about 0.5 volts. That's what should happen in closed loop operation if your o2 sensor is functioning.

anyone else?
