I program for a living. Building the average block logic and viewing the 2o2 sensors separately would not of been hard at all considering the other logic and pids the system already has. Build a parameter to use one or two o2s and build another side loop watching differential of the two. If they get to far apart throw a code and start checking sensors then injectors and on and on. You could essentially use it like a multiport adding fuel to either bank that needed it just not each cylinder. That on the other hand would be duplicating the first control of the o2 and making them seperate yet work in conjunction for overall outcome. Lol
