Look into why the o2 sensors are doing what they are.
Bank 1 o2 pretty much just dies and bank 2 goes way high. I suspect wiring problems or the sensors are at fault.
2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.
If you don't post your tune and logs when you have questions you aren't helping yourself.
I'll check that out. Thanks
Did you figure this out? Looks like maybe O2 sensor signal wires are switched (B1 and B2), which would make each bank drive the PW the opposite direction, creating a larger fuel trim difference. It would be easy to verify that the wiring is correct.
For someone more knowledgeable: Could you switch the injector bank select parameter for each injector over to the opposite bank and would that be enough to make it swap banks to see if that clears it up, or would there be other changes needed or would the sequence be completely off?
