1. An engine calibration system comprising:
an engine including an electronic control unit, wherein the engine is calibrated with an initial engine calibration setting stored in the electronic control unit;
a calibration tool configured to be electrically coupled to the electronic control unit; and
one or more processing circuits, each comprising one or more processors and memory storing instructions that, when executed by the one or more processors, causes the one or more processors to perform operations including:
querying the engine for a unique engine identifier,
sending the unique engine identifier to a cloud-based server,
determining one or more engine calibration settings available to the engine based on the unique engine identifier sent to the cloud-based server,
presenting the one or more engine calibration settings to a user through a user interface so that the user selects a desired engine calibration setting, and
sending the desired engine calibration setting to the electronic control unit;
wherein the electronic control unit is configured to implement the desired engine calibration setting in the engine, and
wherein the desired engine calibration setting is different than the initial engine calibration setting.
