Yea B13.
The altima stuff work fine, put the jumper to 64k, burn the eproms with my back up and turn on the car and work fine, no more check engine :D but these project, I will slowly, because even I do not have the complete turbo kit.
Thanks.

Closed loop is enabled. Is your O2 sensor connected and working?
For the WOT issue, maybe a fuel pressure problem?

Your wide band will read lean while the AIV is active. that's probably what you are seeing at idle. When AIV is activated, as long as the throttle stays closed, AIV stays on for 10 minutes. Time how long you see the lean condition at idle, and if it's around 10 minutes, it's the AIV working.
Not sure about your WOT AFR issue. Hopefully you have a way to map trace your fuel map so you can see what's happening.

Dave is confirmed my O2 wideband sensor is broken, a friend lent me his sensor and my AFR change on idle still on 13.7 - 14.2 and 11.2 on wot.
I'll buy a new wideband sensor, thanks a lot Dave :biggthump
