ABOUT THIS PRODUCT

Dominator EFI Vehicle Management Systems are intended for non-emissions street and racing engine applications. In addition to the transmission control, drive by wire, and dual wideband oxygen sensor options, Dominator systems have nearly unlimited capabilities to control any power adder, input, or output you can throw at them. Need to run a turbocharged, nitrous injected 8 cylinder running water-methanol injection? No problem with Dominator EFI. How about control a 4L80E transmission as well as the fuel and spark on your street rod? No problem. There are also enough inputs and outputs to allow the Dominator VMSs to serve as their own data acquisition and control module. The Dominator VMS will eliminate the need for additional controllers as they are all contained in this one unit. The only thing limiting the Dominator Vehicle Management System is your imagination!
