A twin ignition system for automotive vehicles and the like is disclosed and claimed. Ignition system #1 comprises a known ignition system which allows electrical access to the engine starter, and allows full function of all facilities with which the vehicle is equipped. Ignition system #2 has its own subsystems which can be set to control vehicle speed and/or other vehicle operating parameters. Each system can be accessed by its own discreet key which does not allow access to the other ignition system.
