NOTE: Vortex Ignitions has discontinued
manufacturing their INTERCEPTOR line of piggy back fuel controllers to focus
all their resources on manufacturing their standalone X10 ECU (Engine
Controller Units). Regarding INTERCEPTOR references on DRI website. DRI would
recommend using a Vortex X10 ECU when available in lieu of using the now
discontinued Interceptor. If Vortex ECU is unavailable a Fuel Controller must
be used to adjust for the correct air-fuel ratio.
