Is this possible to do? I'm getting Directscan but want to be able to customize some sort of audible alarm if KR gets to an unsafe #. I've heard of people just buying a seperate knock gauge but a guy I talked to complained about it lighting up at low knock so he couldn't tell the actual kr #'s. I would rather customize directscan to flash red or set off an alarm that lets me know when I am at an unsafe kr level. Thanks for any help.
