Ltft questions for you tuner guys.
Any reason why the fuel trims would be this high and so different from bank1 and bank2? This was at hot idle.

I'm pretty sure the banks should be pretty close together. Do you possibly have an exhaust leak?

Vaccuum leak or a miss will make it read lean.
Does this have a flex fuel sensor or has it been tuned for E72? What do the short term trims look like and do they get better or worse at idle? |

No codes. I have a flex sensors. My shot term trims while driving are -3 to -4 bounced around. I can’t find any vacuum leaks either. Yesterday i had it out and noticed bank 1 would go all the way to +31 on the long term.

Swap the sensors and see if it follows to the other bank.

Not sure if it would matter, but I'd use the same brand that you currently have just in case there might be a difference in others that would affect your tune.
