Battery and Electrical Systems CFI ThrottleIgnition Kill System
System Overview There are two methods for cutting the ignition on CFI systemsThe first is the software stop systemThe software stop system only applies to the throttle flipper switchThe software stop system is activated when the throttle flipper switch is closed (closed throttle), but the TPS (throttle plate position) is still above idleWhen this occurs, the ECU software will determine the throttle cable is "stuck" and kill the ignition system
