    Greetings Sir Charles Murray,

    I would like to be able to manually change the spark timing of my engine from inside my car. During normal driving, pulse spark advance is automatically set by feedback from vehicle sensors. I assume the system is either pulse width modulated or variable amplitude. Wouldn't a simple potentiometer/capacitor circuit be able to modify the signal? If anybody has any intimate technocarnical knowledge of auto spark computers, that would be fantastic.
