Help? Wanting to know if I have a mechanical problem or a tune problem? Bank #1 maxes out at 25 and bank 2 maxes low at -12.5 and bank 1 O2 sensor goes to 0 and bank 2 seems correct and fluctuates in the 800s. Also MAF reading does not fluctuate, I have double checked the wiring, tried another MAF sensor and had the PCM check. I set MAF to read in HZ I see it in my table but not on gauges or chart? This is a mail order tune on a LT1 with 24x LS1 PCM swap, I am posting a log and the tune.
I have replaced both O2 sensors no change and moved injectors from bank one to bank to, but neither made a difference.
So LTFT bank 1, LTFT bank 2, O2 bank 1, O2 bank 2, MAF sensor make no sense, I tried all I know to try, read everything I know to read.
Out of ideas.
