I am getting ready to put long tube headers on my truck and the drivers side header had the O2 bung welded onto the bottom of the #6 primary tube (about 2 inches before the collector). I am using the TT-1 WB and the EBL Flash w/WUD. I am wondering what some initial settings should be for the TT-1 and the WUD ADC Channel filter %. I know I will probably have to try different combinations, but I am wondering if I need to slow down the sampling rate and/or add/subtract filtering.

Can use the default setting of the TT-1 along with the built in TT-1 device in the WUD. For the ADC channel filter, I've used both 0% and 10%, not much difference between them.

We have a page on our site for ADC channel setup:

Can get the latest version of the WUD from our update page:

Be sure to grab the one for the EBL Flash ECM. They are zipped files, so after downloading decompress it. Then move the files (if required) into the proper folder. The zip also contains the latest document for the WUD.

Thanks Rbob. I will set it up. I have been curious to what the benefits of having the O2 read only from one cylinder. Have you found any benefits or drawback to this?

It is probably better to have the O2 sensor in or a little past the collector. This way it reads the 4 cylinders of that bank. Also, the sensor tip needs to be pointed downward. This is to prevent water from getting into the sensor on cold starts.

Ok, well I guess I will try both ways and maybe do a little bit of testing to cull my curiosity.

For reasons not exactly known I was hard on the Bosch WB sensor and had a couple premature failures. I decided to invest in the extension to pull the sensor out of exhaust stream a bit and that seems to have worked. Also i wired key on engine off. The sensor would heat up and would stay on when car started. Accessory pos it would not heat up. I often left the WB on after driving forgetting to disconnect and that too damaged it and drained battery. No more.

I have been curious also as to how wire the sensor in like you described. How did you do yours?

My son in law did for me. He is an electronic guru. I know it takes a relay. The schematic is on innovate site. He did my N20 set up as well...

Ok, thanks. I will check it out.
