Description

Fits GM LS 58x Crank, 4x Cam - 4.8/5.3/6.0 style Engines with EV1 Injectors

Part Number: 550-651

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!
