You can turn off the downstream O2's on your XCal2 tune instead of making MIL eliminators for them. It's way easier, but you won't have them for comparing bank readings. IMO, it isn't a big deal, especially if you have a wideband sensor hooked up correctly with a good tune.

BTW, congrats on your 3L!
