ADJUSTING AN INTERNAL COMBUSTION ENGINE

A computer system includes a processor and a memory configured with instructions executable by the processor to determine a fuel configuration in response to input received by the HMI, determine fuel composition constituents in response to at least the fuel configuration, determine one or more fuel properties in response to at least one or more fuel composition constituents, determine one or more engine controller adjustments in response to the one or more fuel properties, and provide the one or more adjustments to an engine control system. A human-machine interface (HMI) is operatively coupled with the processor, and a memory and may be utilized to provide commissioning or service inputs.
