Hello men , I was wondering about pinging / detonation issues when setting the ATS at /or above 4 degrees of advance . I've read some posts of yours that you are getting pinging even @ 4 and some have no issue with pinging . I have mine set a +4 but have yet to start her up for the first time with it installed . This is steel framed bikes only as they seem to have less tolerance for advance . I'm wondering if certain upgrades affect this also , IE; Intake , exhaust , cams etc ... Any input would be helpful .
