Dominator® EFI Vehicle Management Systems cater to non-emissions street and racing engine applications, providing extensive control over power adders, inputs, and outputs. The systems offer unparalleled versatility, enabling seamless management of a turbocharged, nitrous-injected 8-cylinder with water-methanol injection or simultaneous control of a 4L80E transmission, fuel, and spark on a street rod. With ample inputs and outputs, Dominator® VMSs can function as an independent data acquisition and control module, consolidating various controllers into a unified unit. The only boundary for the Dominator® Vehicle Management System is the user's imagination.
