The presently disclosed subject matter relates to an apparatus which enables a use to easily and safely disable a vehicular variable cylinder management technology system, while enabling restoration of the VCM/ECO mode under certain vehicle-related conditions or driving conditions. The presently disclosed apparatus comprises a potentiometer capable of modifying the voltage input received by the vehicle sensors.
