umm yeah.. i was adjusting my timing to hear ping then bakc it off. well i didn't hear any ping but i turned my dizzy all the way.. checked wiht the t-light and it's at like 22º judging from the stock timing mark spacing.. runs fine, no ping, seems like i gained a little top end so i left it. i need a dial type t-light tho
BTW you gotta jump the service connector before you make adjustments to get accurate readings
