A spark advance controller capable of controlling spark advance in an internal combustion engine with high accuracy without requiring a larger number of data maps and performing laborious optimization tests using an actual engine. In the spark advance controller, map data for controlling the spark advance is computed by a numerical simulator simulating an internal combustion engine, and the map data for spark advance control is approximated with a regression model. The spark advance is computed by using the regression model depending on the detected operating conditions.
