I am sure there are other factors too.

When it isn't in closed loop mode the AFR is mapped. So, it is not correct to say that when not in closed loop it is significantly richer. Some portions of the map may be nearly as lean as closed loop (14.7:1).

Anyway, I realize that the 14.7:1 area is too lean for most people's liking, but regardless of what you do with A/C and exhaust, the closed loop portion of the bike will be 14.7:1. Adding a voltage splitter will do nothing for the times the bike is in open loop mode. This is the area that your fuel maps will be too lean and the bike cannot compensate for this condition.

If all you are doing is A/C and exhaust, I would recommend the download from the dealer.
All I can say is.....WHAT.....!!!!!.......
