is some info in this in the VFI instruciton manual 510-0011
which implies that the closed loop offset is at the maximum it is allowed.

(unless you have a crack in the manifold or something or fuel pressure)

Map Merging:
If a DTC has been set for front or rear Adaptive Maxed Out it is possible that a map merge needs to be performed. Motorcycles using oxygen sensors
with closed loop fuel control will learn adaptive fuel based on the feedback from the oxygen sensors. These adaptive fuel values apply an offset
to the main fuel table to maintain an air fuel ratio that matches the settings specified by the Target Closed-Loop Fuel Map. There are limits though
to the amount of fuel that can be added or removed by the closed loop fuel system. If the adaptive map values reach the limits of closed loop fuel
control the check engine light will illuminate and a DTC will be set for the related front or rear adaptive maxed out. When this occurs ProTune II can
be used to merge the values of the adaptive fuel control into the main fuel table. This creates a new fuel table and resets the adaptive fuel maps to
allow closed loop fuel control to have the full range of control again.

THE PROBLEM IS THAT YOU CANT DO THAT MAP MERGE. YOU ARE NOT ALLOWED.
