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?

 

you have to jump the service connector to set base timing since if the service connector is not jumped then the ecu changes timing

 

So since i didnt jump the service connector you think the timing isnt actually what I set it as according to the crank pulley? The ecu wouldnt set it back to stock settings at 16 degrees? Cause really thats all I want to do. How would i correct the timing since the ecu has taken over? Just jump the service connector and use the crank pulley and distributor again?

 

Shorting of the service connector disables the ECU from being able to advance or retard the timing while your trying to set it.

 

If you let the car fully warm up (fans have come on at least twice) shorting the service connector will only make a 0.5-1 deg difference, if it makes a difference at all.

 

i kinda figured...cause i have 2 friends that are honda techs and they never jump the connector when they do timing. But also how do you guys really know if its accurate? or do you guys dont know?

 

When you're looking down at the pointer, you have to use a POV that allows you to only see the triangle on the top of the pointer. If you can see the faces of the pointer sides, then you're looking at it crooked.
