Engine Management Systems have always interested me so I'm going to try building one, only problem is I know very little about the input and output signals that an EMS requires.</DIV>
<DIV>Listed below are all the inputs/outputs that I KNOW are used. If anyone knows of anymore then could you please tell me and include what the function of the input/output is.</DIV>
<DIV>INPUTS</DIV>

<DIV> Ping Sensor: Detects detonation.</DIV>
<DIV> Crank Angle: Used a trigger for firing each spark plug? NOT TOO SURE ABOUT THIS</DIV>
<DIV>OUTPUTS</DIV>
