If you want something to view live data you're better off with something like a Dash Hawk or a Scan Gauge II.
While one is better off getting something different for monitoring if all you want to see is gauges, you can use the X3 for display only. You will not have gauges but you can view the numbers live. When you set up the log you can turn off the recording and monitor for however long you want.
