ignition timing

I have a 1996 F150 4.9L, I was wondering if you can adjust your igniton timing or is it controlled by the computer?

I belive its adjustable, but you have to remove the "spout" connector (I think OBD-IV still had these) and then hook up your timing light like normal. Just remember to connect the spout connector again, or your timing won't advance as the computer controls it.

Good luck.

juju you have obd II and you can bump the timing between 10 and 12 degrees. 10 degrees is stock.

Is there some performance advantage to bumping your timing on the 4.9L ?

Do you have a best case setting in mind?

I used to do it in my '71 Satellite's 318 but I always timed that by ear anyway.
