Looking for a plug and play kit for your GM LS engine? The HP ECU allows you to accurately control the fuel and ignition of your engine plus much more. Got a stock LS engine? Simply download a base map and you're on your way. Got a turbocharged, nitrous fed LS engine on water/meth? This HP EFI kit can control that too!  Or, if you need the features offered only by the Dominator ECU, you can opt for that as well.

ECU is certified to ISO 8846, SAE J1171 & United States Coast Guard Requirements for Ignition Protection & Fire Resistance.Holley HP EFI systems are equipped with 4 programmable inputs and 4 programmable outputs that are ideal for most vehicles with a single power adder. This feature allows the user to configure the system to support a wide range of controls including boost control, progressive nitrous, water/meth injection, speed inputs, fuel pump control, AC inputs, timing retard inputs and various other uses. When selecting an ECU, users need to ensure their planned controls can be run with the 4 inputs and 4 outputs as certain combinations may use more I/Os than are available. If more I/Os are required, users should choose the Dominator VMS.

Free ECU Setup--Seriously?

For a limited time when you buy one of our Holley HP and ECU Kits we will ship it pre-configured for your basic setup at no additional charge. That means as soon as you get everything installed this should give you the ability to crank the engine--much like the Setup Wizard does on systems like the Sniper or Terminator. Note that this does not include tuning services or setup of things like nitrous control, boost control, transbrake setup, etc. However, whenever you purchase an EFI System from EFI System Pro you get our Level 3 Platinum EFI System Support at no extra charge. We're going to be there to help you be successful with your EFI system installation!
