About the Holley Dominator ECU:

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 4L60E 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!

About the BigStuff Gen4 ECU:

BigStuff is a Southeast Michigan-based company focused on the design, manufacture, and marketing of state-of-the-art electronic engine and power train controllers for the performance aftermarket. Bigstuff is proud to be one of the last USA based ECU systems in the aftermarket. We utilize only USA based manufacturers from our ECU’s, Injector Drivers, Dashes and Wire Harnesses. We will whenever possible keep our American companies working rather than send our money overseas.

Our current GEN4 offering has hit the aftermarket and we are getting rave reviews from our customers. The GEN4 ECU started as a blank slate on how we could best serve our current GEN3 ECU customers while also bringing the latest state of the art technology to the aftermarket. The GEN4 ECU is designed to drop right in place of the current GEN3 ECU which makes the swap to the newest technology on the market so simple.
