Disable Rear O2

[GoobyFRS]

Keep getting P0140 CEL. Rear O2 No Voltage. I double checked the connector, everything looks fine. So I figure it's just shot.
I installed catless headers 5 months ago and have been running the OFT OTS Stage 2 UEL 91 oct tune since. About 15k miles.
Gonna buy a new O2 sensor at some point, but can't right away, so I want to disable it.

So from reading other threads I understand I need to 0 all inputs in the Closed Loop Fueling Target Compensation B (Load) in RomRaider.

So, I'm thinking I should 0 those, and then in the Primary Open Loop Fueling leaning out a bit around Idle to help compensate from running at 13.4 AFR like it has been.

Set af#3 corrections to zero

Would that normally be in the Fueling - AF Corrections / Learning folder? Because I don't seem to have anything anywhere in my rom with AF#3.

AF3 correction in my defs under Fueling AF correctiom /Learning

try attached definition but check tables and make sure its matched to your rom

Zero af3 tables then disable cel code for o2 voltage. I've been running with zeroed af3 tables for a year with no noticeable issues. Another thing if you intend to buy a new o2 sensor. Going catless might be why the o2 deteriorated prematurely. I bought a new o2 but left my bad o2 in for my catless header.
