Ok, so providing it's mapped correctly, the only thing you can do is adjust the CO pot (i.e.a screw on the ECU) assuming you are not running closed loop.
The thing is yours will probably have had a live map, given there are no off the shelf calibrations for the CVH, as it's not the standard management.
This means you don't know what the CO value should be, only whomever mapped it will.
Be aware, there may be an underlying fault(s) causing this ranging from an air leak to sensor issue.
