So went to mess with my wife's impala today. It's an 09 with the 3900. I reduced both engine and trans tq management. Went for a drive and the data logger is reading ltft for o2 bank 2 at +100. Any ideas why? Ive only had hptuners about a week so I'm not sure where to start.
You could try removing them from the main channels list, then re-add them and see if they read again.
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 tired and didn't work. My voltage is reading .005. Does that mean the o2 failed? That sensor reads fine on my truck
The check engine light would be on and a code for it if the voltage was basically nothing.
It's possible some of the stuff isn't supported/working and they could fix it for you.
I'd try emailing support at hptuners and include the tune file and a log file of the problem along with what you have tried to do to fix the problem.

Sounds sort of like the O2 tanked, odd coincidence?
Some of impalas have only one o2 Sensor i think, Open the Bank map ( Engine > fuel > General > Injector bank select ) and check if there is a bank map or all fields are in 0 bank.
