Newbie questions...

Ok, in the scanner, is there a place where I can see my timing? I ask because I am getting quite a bit of KR when I put my cruise control on @ 70 in 6th gear. The KR doesnt come into play until i go up a hill. I have long tubes and an air lid, thats about it. I would love to tune my car a bit, but I dont even know where to begin. For the most part I have just gotten rid of some codes. Any help is greatly appreciated :)

Yes. It's right nest to the KR bar graph in the Digital Dash mode of the scanner.
