Holley Dominator Efi Ecu

The Dominator® EFI Vehicle Management Systems are engineered for non-emission street and racing engine applications, offering exceptional control over various power adders, inputs, and outputs. Whether you're running a turbocharged, nitrous-injected 8-cylinder with water-methanol injection or need to control a 4L60E transmission along with fuel and spark on your street rod, the Dominator® EFI has you covered. This system provides virtually unlimited capabilities and serves as its own data acquisition and control module, eliminating the need for additional controllers.
