The ignition control module will still provide rudimentary advance when disconnected from the ecm. If your idle speed is too high you may be seeing this advance. Try dropping the idle speed down with the ESC connector (four plug pigtail going to the rear of the dist) disconnected. For TPI engines there's another connector that can be disconnected that will do the same thing but you can pull the plug at the dist to be certain.
