Maple syrup will not substitute for corn syrup as it has more star content. If it's boiled down further to reduce the water content, it can be substituted directly.
Another great option to get great maple flavor is to use crushed maple candy, or maple sugar. This is syrup that has been boiled down into a soft, crumble candy or sugar, like brown sugar, only maple. It's much harder to find now days than it used to be. If you can find it, it's a great flavor treat.
