An electronic engine controller (12, 12a, 12b) has a processor (56), a data controller (64a, 64b), and a non-volatile memory (66). During an engine operation, power is supplied to the processor, data controller, and non-volatile memory from an engine power source. Sensor data (54) is received at the processor which supplies the sensor data to the data controller. The data controller stores the sensor data in the non-volatile memory. During data retrieval, power is supplied to the data controller and the non-volatile memory from a USB communications channel (65a, 65b). The data controller retrieves the saved sensor data from the non-volatile memory and provides it to the USB communications channel.
