Spark advance?

The typical setting is 0. This doesn't mean that the advance is zero but the degrees of advancement from the baseline is zero.

If you advance it too much, the computer will automatically start pulling timing. Often it pulls in large amounts and makes people think they need to then advance more. You probably aren't at the point yet but if you keep a spread sheet and have a very regular route, you'll be able to see when it yanks a bunch of timing because performance and mileage will drop. I would not keep raising the timing advancement without running higher grade fuel.
