"SafeGuard retards timing if knock is detected, protecting your engine from destructive detonation.
The control system retards only the knocking cylinders, maximizing power while protecting the engine.
The system also features boost retard and nitrous or switched retard.
The boost retard section includes Start and Rate controls, allowing you to tailor the retard curve to your needs.
Switched retard could be enabled by a nitrous switch or a manual toggle switch, in case you fill up with low octane fuel."
