You can do that but I'd probably look for a single readout that will read both gauges. With the LC-1/2 you would have to run a second gauge. Most people just monitor one bank. I recommend bank 1 (passenger side) because it seems to run slightly leaner than bank 2. If you don't have the bung in either the downpipe or lead pipe just have a bung welded into the lead pipe of the FI exhaust. A muffler shop should be able to do that pretty quickly at a low cost.

Chuck - I can't recall off the top of my head, but where's your AFR O2 sensor located?

Edit - Innovate makes a single gauge dual wideband but I can't seem to find it any place but eBay for instock purchase so it might be discontinued.
