Sturman Industries’ second-generation S-TEC (Sturman-Total Engine Controller) is designed to be fully capable and configurable. As a user-customizable controller, customer support options for the Sockeye S-TEC are available from bare board purchases to turnkey solutions. According to Sturman, in its standard configuration the Sockeye offers an extensive I/O set capable of operating most gasoline, diesel, and alternative-fuel engines, including JP-8 for the military. Further customization is available to achieve application-specific requirements for size, weight, functionality, and ruggedness. The Sockeye units are delivered with the Sturman CALibration Editor (SCALE) interface software, which provides capability to modify the calibration gains, tables, and variables. No additional software is required for operation. Optional libraries provide basic engine control unit functionality algorithms for compression-ignition or spark-ignition engines.
