Where in value should the Knock Learn be at?Is it a value that you can set?I'm thinking this could be the issue I'm having.Traver

Still can not find the timing issue at all.Sent my file to many good tuners and they are stumped as well.The car is a blast to drive and hooks like glue from take off.The question I have now is could this timing being pulled back on launch helping me or still hurting me?I see it pull back to about 3 degrees most of the time from 24 degrees right off the line.
