The upgraded CDF II detector has collected first data during the
initial operation of the Tevatron accelerator in Run II. The simulation of
the CDF electromagnetic and hadronic central and upgraded plug (forward)
calorimeter is based on the Gflash calorimeter parameterization package used
within the GEANT based detector simulation of the Run II CDF detector. We
present the results of tuning the central and plug calorimeter response to
testbeam data.
