    554-114 is rated 5.0 out of 5 by 1.
    Rated 5 out of 5 by from The Dominator system is awesome! I upgraded from the HP computer to the Dominator. They function the same, but the Dominator has the ability to control anything and everything. The additional inputs/ outputs are well worth the extra cost. I wish I would have gone with the Dominator in the first place.

    I want to convey my 2010 Nissan Frontier pro4x to run on ethanol/alcohol. Excluding physical mods, will this unit allow me to make all the adjustments for that?
