Disable Rear O2
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. https://gyazo.com/0b54a6c17dda6a4e338f42fe068d25d7 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. |

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.

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.
