Abstract
A spark ignition engine system for communicating data includes a capacitive discharge ignition system using a microcontroller for controlling the spark ignition of a light-duty internal combustion engine; a memory device communicated with the microcontroller, wherein the micro-controller obtains engine data from the light-duty internal combustion engine and stores the engine data or software using the memory device; and a powering connection and a separate data connection that are electrically connected to different pins of the microcontroller, wherein the powering connection supplies power to the microcontroller while engine data or software is communicated via the data connection.
