Holley Dominator EFI is the top of the Holley EFI line, built for non-emissions street and race engines. On top of fuel and spark, it runs transmission control, drive by wire and dual wideband O2, and it has enough inputs and outputs to handle turbo, nitrous, water/methanol and act as its own data acquisition system, so you don't need separate controllers.

Fits: Conventional pushrod Ford engines with EV1 injectors.
