Checked my friends timing on his b18b and it seems like his timing was retarded at like 12 degrees...which probably contributed to his low trap a few weeks ago at the track. So I advanced it to 16 but then after we finished I check it again and it looks like 15-15.5. The lines are kinda hard to see and its kind of hard to line it up with the arrow cause if you move your head it looks different. How do you really know your timing is accurate?? And do you really need to jump the service connector? What is the purpose of this? We didnt...hope that didnt effect anything. Also for you b18b guys what timing felt good on your car?
