If you are not getting enough live data, there are several actions you can take. To make sure that you are getting as much data as possible from your current hardware, you should make sure CIUMon is running at high priority. You may also wish to adjust CIUMon's timing. As well, make sure that CIUMon is connected at a baud rate of at least 600.
In addition using RoviSys Turbo can greatly increase the amount of live data you can get.
