The upgrade of the COSY-TOF experiment with the Straw Tube Tracker and the Silicon Quirl Telescope improves both mass resolution and reconstruction efficiency significantly. Due to its large acceptance and azimuthal symmetry the COSY-TOF detector is an excellent instrument to study complete Dalitz plot distributions of 3-body final states with strangeness. Experimental data from the first physics run with the upgraded detector are being analyzed. For better understanding of the detector response and optimization of the analysis algorithms MC simulations were done. Simulated events were transported through the detector using Geant-3. After digitization the detector response was reproduced. All studies were done within the TOF MC package. Results of the MC simulation will be shown in comparison to the first experimental results.
