I was doing some WOT runs yesterday trying to dial in my meth. After a couple decent 10psi pulls ( 2k - 7K ) I noticed the car was running pig rich. IE: 9-10AFR during driving conditions. I took the car out of CLSD to run OLSD and the problem went away. It appears that my B1S1 NB02 got fried. The B2S1 NB02 is new but, I am seeing some flux in the scan.
I have a battery relocation and am using the seat bolt for my ground. I have been advised to take it out to the frame. Do you think the poor ground could cause the flux in 02 readings?

Sup Jerry. You definitely want a solid ground for the battery. Log the ltrims at wot to see if they are affecting wot fueling. Same thing for part throttle actually.
Water in the exhaust is an issue even without a water injection and that's the reason the 02 sensors must be between 9:30 and 2:30 on the clock position in the exhaust. Not saying this is the problem because I'm sure whatever exhaust you have has them properly positioned.
Good voltage is everything to electronics. Good grounds are everything to good voltage. Seat bolts do not equate to good grounds.
Is this TXZ0603 Jerry??
If so, I've been worried about you!! Called your # and got nothing and considering the recent history, that worried me.
