Can this gauge read misfires? If so how do you do it?

The gauge will only show the missfiring cylinder if it sets a code, say a po301 if cylinder 1 is missfiring enough to set a code, or a po300 if multiple missfires. Other than that, i havent found data stream that shows actual missfires on the areoforce.

 

alright that all I needed to know. So you cant see it unless a code is thrown.
