I just wanted to know where do you guys weld the o2 bung for the wide band 02 sensor on a the following:

1) Full catback exhaust sytem

2) Hytech side exit race header?

<U>Current Delima</U>

I got an innovate LM-1 and currently have the wideband 02 bung welded in my staright pipe cat replacement. Got an error code 8 which states that the temperature on the wideband o2 is greater than 900 degrees and malfunctioned after a few WOT runs.

I ordered another wideband o2 and the HBX-1 heat-sink bung. Installed the heat-sink and went to tune the car. After a couple days of WOT, I got the error code 8 again.

Do I need to relocated the wideband o2 sensor more down stream? Some say 2 to 3 feet after the cat, others say 2 to 3 feet before the muffler tip.

Any ideas.....

Future Delima:<U></U>

I just ordered a hytech side exit drag headers and should be done in a few weeks. I was planning to have John G. weld in another bung for the wideband o2 sensor. I predict that the same error code 8 would occur again since it is happening when the o2 is mounted on the straight pipe of my current setup.

How do I solve the issue of burning out the wideband o2 on my current setup and how would I prevent it from happening on the hytech side exit drag header?

Please any ideas.....

 

Something funky going on with your setup. My LM-1 O2 sensor was mounted in my header, and never overheated or diplayed any error codes.

 

How is it to be mounted? Could the way it is mounted cause problems. Currenty it is mounted at 3 o'clock on the staright pipe cat replacement.

Any other inputs....

 

I've used my sensor as close as 6" from the turbine outlet on a 335whp car doing street tuning and dyno tuning over a whole day's time. It never once gave me an error code.

Maybe there's something wrong with the heater circuit.

 

This is the second o2 I've gone through. Only error code 8 shows. Any suggestions, should I get another replacement o2 from innovate?
