0411 swap O2 sensors issue
Based upon my research, the injector bank select is the problem. If it's not matched properly to the actual setup, the fuel trims will eventually go full positive on one side and negative on the other in closed loop.
The firing order table is simply for troubleshooting a misfire on a specific cylinder , so obviously we will change that as well.

I mean there are so many tables that have been changed for no reason from what a stock 2002 f-body has I would be starting over with a known good stock file. Lots of those table changes look like just copies from another OS and that never works out right and always causes a problem of some sorts. Deka 60s certainly don't have a 1.16 msec offset at 13.0V, it's using the boost enrichment table which can have delays, one knock sensor fitted, PRNDL enabled, this looks like a ton of tables were just copied out of a truck OS. Yeah, I would be starting over for sure.

That's correct. The first tuner grabbed a truck pcm, that's how all this started. My tuner and I have gone through and already fixed quite a few things. Tune related and also wiring related.
If the o2 sensors work after this, I'm going to call it good. The car runs amazing and strong otherwise with a very safe AFR.

With my tuner out of the state, and me being slated to pick up HPT in the future, I'd like to know more about these things right now. The PRNDL enabled doesn't appear to make any difference. 1,2, D, OD all seems fine.

Met with tuner today. We got the injector bank select corrected as well as a couple other things.
O2 sensors worked perfectly immediately after adjusting the injectors.
SOLVED!
