How about this.. i noticed, now i have smooth idle and afr gauge shows 11.7 to 12.3 but tunerpro dash says my o2 sensor voltage is .760 to .840

o2 is showing it rich, if it was 15-16 afr it would probly read 200-300. where is the blm reading that is all I have to adjust with?
blm is 108-112
could my almost new denso 02 sensor be somehow bad or could there be something else messing the voltage from it...
i found that i can adjust 02 sensors error in bin, also for idle but ,500 is too much error i think...

in your bin the mean which is the midrange is set to .499 so the o2 is proble working right. egale mark had a thread on here about using data trace while you are tunning, if you type data trace in the serach box it should appear it might help in sorten things out.

I know how the data trace works in tunerpro

here is some datalogs... im not commenting at all, its up to you...
oh.. i can seay something, drivibility is poor, engine nearly dies when coming to stop, i got lean bog at intake when accelerating... and that o2 rich eror when in closed loop...
