I think he is talking about one of the hidden features on the on board computer.

Instructions to access the hidden OBC functions:
1. Hold Trip Reset while turning ignition key to on position
2. OBC should show "Test"
3. Use Trip Reset to select function 19.0 that unlocks all the features
3. Wait for display to show "Off"
4. Depress Trip Reset for 1/4 second and release it
5. With no delay press Trip Reset several times to select the following...

7.2 + Engine speed / Current RPMs 1/min

This will show your current RPM in a digital readout on your dash.
