Abstract
Systems and methods are for controlling combustion in a marine drive. The systems can include a computer processor device and a computer memory device comprising instructions. The instructions are executable by the computer processor device to control a timing of spark in an engine, by determine a base spark advance based on a predetermined nominal humidity, a load of the engine, and a revolutions per minute (RPM) value of the engine. Additionally, the instructions are executable to determine a humidity offset value based on a specific humidity of intake air to the engine and the load of the engine. Further, the instructions are executable to determine a controlling spark advance value based on the base spark advance and the humidity offset value. Additionally, the instructions are executable to send the controlling spark advance value to an ignition system of the engine.
