Abstract
Recreational vehicle two-stroke engine control systems configured for location-based modification of an engine calibration may include a locator device, a throttle position sensor, and an engine speed sensor communicatively coupled to an engine control unit. The engine control unit controls a position of an exhaust valve based on a first calibration map and an input from the sensors. The engine control unit also determines, based on a location of the vehicle, a second calibration map. The engine control unit controls a position of an exhaust valve based on a second calibration map and an input from the sensors. Controlling the two-stroke engine to operate the exhaust valve at the second exhaust valve position may improve the engine run-quality, performance, efficiency, or the like.
