Offset values for dual pointer flap gauge (Simkits)

Hi All,
I purchased a Simkits flap gauge, and have set up, and calibrated it fine.
However i still cant seem to work out how to get the FSUIPC offset values to register within the simkits setup.
I know the offset values for left and right, but nowhere do i see any option to enter those values in the setup.
If these values exist within FSUIPC, then i dont understand how to get FSUIPC to interface with the Simkits setup.
Help Appreciated,
Regards
TOM
