In doing some research on DIY WideBand setups, several talk about installing the bung in the headers, but my headers already have a bung and O2 sensor. Will I need to install a second bung, or can I use the same one (once I convert the prom to read the WB data)? I am understanding that it is possible to tell the 730 to read the WB voltage right?

 

Most people put a bung in the other header.
While the bin can be setup to read the WB.
The ECM will not work in CL with a WB.
They are two different things.
