This HP EFI ECU and Harness Kit is designed to make upgrade from the factory GM
fuel injection on GM TPI applications hassle-free. The harness is designed to
run to all of the factory sensor and injector locations, but they go the extra
step and include the O2 sensor (your choice of Bosch or NTK), MAP sensor, air and coolant temperature
sensors that you will need for the job. This same ECU/Harness kit is the one
that Holley specifies for their Stealth Ram intakes, so it includes the throttle
position sensor that works with both applications. Even the IAC connection is
there to let you set up a smooth idle. Not only is ECU main power included but
it also has the ignition timing pickup adapter. If you're not converting
from TPI and need to replace the mechanical fuel pump, there is even a blockoff
plate for that. It's all there! And if you are trying to decide between the HP and Dominator ECU we help make that choice easier by offering to upgrade the ECU in this kit.
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!
