Watch and Record

[MikesMag]

Well it's been a long time since I have been here.
I have a 05 Magnum with the following mods:
Heads and cam from Franks, JBA shorties and Hi-flow cats, K&N CAI, Borla catback.
Diablosport Predator 7135, not updated since(version 9r04).
Unfortunately. I never got a tune from Franks.
I've been running the 93 CAI performance tune with no issues.
All work was done around 2007 ish.
The car has been great, I don't drive it much(90k miles).
Until now.
I started getting P0420 codes, they would come and go.
Now it is all the time.
If I reset it, it comes right back.
I installed the extensions on the rear O2's.
Still coming up.
I am in NJ so I need to correct this for inspection.
I used the Watch and Record while driving around last night.
I was monitoring the o2s 11(and 12) Goal Volts and o2s 21(and 22) Goal Volts signals.
Is there a way to determine which signals corresponds to the o2 sensor locations?
o2s 12 was at 2.75, 21 and 22 were at 2.75(steady)
11 on the other hand was varying about a half a volt and very erratic.
Has anyone ever ran into this?
I was going to delete then, but I understand it will cause a un-ready state and that wont pass either.
Sorry this is so long, I figured I would post as much info as I can,
Mike

Update, I found elsewhere on this site about the sensor codes(11=1/1 etc).
I am confused on which side is which, I looked on LXforums and found the Bank one was the Passenger side and
on other sites, Bank one was the drivers side.
Can I get a correct answer on this?
Thanks!

bank 1 is drivers side.
