I'm getting around 10:0.7 reading at WOT.
When I'm just driving normally, it's more like 15:0.6...
I've never actually seen the o2 voltage hit 1 before.

Only running 12psi.

These are readings off of the apexi turbo timer, it has afr and o2 displays on it. LOL

I know that narrowband isn't accurate at all, but could this show me signs of anything? Like a bad o2? Do you think I'm actually running as lean as it says?
Or should i completely just ignore those readings and get a wideband?

I'm ordering a palm mmcd logger ASAP to see how much, if any, knock I'm getting.
 
Everything you posted sounds like normal function. Why do you think you're running lean?
 
Correct me if I am wrong but... I'm almost certain narrowband's are worthless.. And you need a wideband to tell for sure if your running lean or rich.. Using a turbo timer to monitor this sounds ... like it wouldn't work.
 
Narrow bands o2 gauges ARE worthless. I would definitely get a palm logger. With a palm logger you can monitor your fuel trims if you see a trend in those in one direction or the other you will know if your needing more or less fuel.
 
You are running VERY rich for WOT on 12 psi of boost. Needs a major retune
 
You guys are missing the point. A narrowband o2 gauge is useless for reading a/f. A narrow band o2 is only a switch between high and low. It does not provide a real reading.
