The MEG II experiment is designed to improve by an order of magnitude the sensitivity of 4.2 x 10(-13) reached by MEG on the search for mu(+) -> e(+) gamma decay. A pixelated Timing Counter (pTC) has been developed to improve the time resolution by measuring the positron time information independently with several counters. We constructed and installed the pTC and performed commissioning runs at the pi E5 beam line at PSI. A resolution of 38.5 ps is obtained with commissioning run data.
