Very very simple question about the Scantool


86 GN
After I've made a "run" and I want to see what the #s on the Scanmaster do I retrieve all them.
I'm concerned about knock.....and just want to make sure I'm reading the "correct" thing. Isn't there somewhere on the scantool that will also show we "at what MPH...or at what RPM" any potential knock occurred??

Sorry for such a basic question....just don't want to break anything on my car thinking I'm reading something on the scanmaster that's not right.
Push/hold button on right for 02's & Deg KR. Push/hold both buttons down for mph of KR occurrance. Of course, once you turn ignition off--the records are lost & you're starting over...
