I have heard of many people having issues with 02's sensors and LT headers due to the lack of heat I guess. So my question is has anyone found a 02 sensor that responds well with LT's? I am thinking of going back to CLSD and need some new 02's.

 

I had to replace mine with Bosch O2's. Works so far. I think it is due to increase in heat. They burn up.

 

I don't think it's due to burning up. I have an EGT gauge that says different. I went with the vette rears, due to the higher wattage heater in them. No matter what you choose sometimes it works for others and not for some. So many variables. I shortened the switching of the o2's (switching is the problem anyway) and it seems to work fine. Hell I even get a little leaner PT driving with the o2's swithcing shortened.

 

You got what sensors dewey? The vette rears, for use in your bank 1&2 upstream sensors correct? How much did you have to shorted the switching?

 

Damn Replacements are expensive, where are you guys getting yours from?

 

i bought the vette 13111 sensors. My switching is

350.01358 350.01358 350.01358 350.01358 350.01358 350.01358 451.01235 539.98504 580.00406

in the 02 Rich/Lean vs Airflow tables


and 24.00000 31.00000 43.00000 51.00000 51.00000 51.00000 43.00000 43.00000 43.00000
in the closed loop porportional base vs airflow mode


I have a cam as well, so there is need for my adjustments as well. You may n ot need such refining of the rich/lean interpretations.

 

I just got raped in the butt for mine. Just under $200 from O'Reillys

 

I have no idea what you just said.

The vette o2's have a different connector, I guess you just cut and put the other connector on?

 

That's what I did, yes. Just match the numbers on the ends.

The confusing part above is if you have access to tuning software.

 

My 02 rich/lean vs. airflow is 451 across the board.
