EA82 Ignition Timing, Green Connector?

[Rollie715]

Well, I got the new motor in this past weekend and proceeded to set the ignition timing. The hood sticker for the 88 GL wagon SPFI 5-speed said to use 18 degrees before TDC at about 700-800 rpm with the green plug connected.

 

It appeared to work ok except I didn't notice any difference in the timing light reading whether the green connector was connected or not. In both cases the timing would advance as the rpms were increased. I thought the green connector was suppose to disable the auto advance so that the correct timing could more easily be set.

 

Anyone have more info to shed on the function of the "green connector"?

 

Scott in Bellingham was helping me and he said when he did the same thing on his car, plugging in the green connector made an obvious difference.

 

Do you suppose my green connectors may have a loose connection somewhere?

What the green connector does is basically the same thing as taking off the vacuume hose off the distributor on an older model, its sets the timing to "base" timing.

 

 

As far as it making a difference, it really depends on conditions, sometimes it made a difference on mine, some times it didn't.

 

Just a thought though, IIRC, base timing on an SPFI is 20, not 18, should make the car feel more peppy.

I thought that was what is was supposed to do. The confusing part for me, is that when the green connectors are stuck together, I still see the timing advance as the rpms are increased. Even a change of 100 rpm shows a difference. This makes me think the disable auto advance function of the green connectors are not working like they are supposed to.
