I found this thread today while doing research before ordering the Innovate DLG-1. Can someone correct my thinking and tell me if I am off base here. If I have this set up to read at each bank before the X-pipe, I would be able to see a rich reading on one side versus the other if I had a plug foul, correct? This is assuming both sides have been running similar to start with. I am thinking this would be an out of the box way I could be sure things are still ok day to day. I have a 526" and have had a plug wire burn already and didn't catch it right away because the cubes and stroke covered it up.
