Holley's HP ECU and Harness Kits are the perfect solution for individuals either converting a factory fuel injected engine to Holley or for those who are building a fuel injected engine with key components that they have sourced separately (intake manifold, throttle body, fuel injectors, etc.) This particular ECU/Harness kit for universal MPFI applcations provides a maximum of design flexibility at the sacrifice of some of the conveniences of a fully terminated harness.
Included in this kit are not only the Holley HP ECU but also the ECU power harness,
the universal main harness, a v8 harness for fuel injectors with Bosch-style
connectors, and an adapter for picking up ignition timing. Additionally,
fundamental sensors are included, such as a Bosch Wideband O2 sensor, a coolant
and air temperature sensor, and a 1-BAR MAP sensor. Beyond this, other basic
hardware pieces are included, such as connectors, fasteners, firewall grommet,
O2 sensor weld-in bung and even a mechanical fuel pump block-off plate for
those who require one. The HP ECU is feature-rich, and comes with the required
USB cable and PC software for setup and tuning. Or, upgrade to the Dominator ECU without having to leave this page.
The Bosch Wideband O2 sensor is ideal for applications that will never run
racing fuel or be subject to extreme forced induction applications. For harsher environments the NTK sensor is preferred.
Do The Job Right--Add A Connector Kit!
Just because you're installing an unterminated harness doesn't mean you have to go it alone when it comes to connectors. If you have one of these popular engines you can get the exact sensor connectors you need to finish the job professionally!

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!
