-10% Sniper EFI Self-Tuning Kit - Shiny Finish

Ok, so tell me more about Sniper EFI 

This should erase all doubts you had about EFI! Whether you were holding out because of price or difficulty of setup, the Sniper EFI system kills both of those tired old excuses. Now you can have all of the benefits of a high-end throttle-body EFI system without laptops, software, tuning, wiring harnesses, or even an ECU box. That's right--carburetor simplicity with crisp EFI functionality.

If you have an engine with a Holley 4150-style intake manifold then you are ready to start installing. Bolt on the throttle body, put the linkage in place, connect the power and O2 Sensor, provide an EFI fuel supply. All that's left is walking through the guided setup quiz (with not-so-tough questions like, "what is the displacement of your engine") and the ECU located inside the throttle body itself does the rest.

Features:

  • Direct Fit for 4150-style Intake Manifold (adapters available for other manifolds)
  • The ECU is in the Throttle Body--No boxes to mount, no complex wiring harness to run!
  • Connect with as few as 4 wiring connections: Power +/-, Ignition, and RPM Signal
  • Fuel pressure regulator and most sensors are built-in
  • Visually amazing 3.5-inch touchscreen provides both setup and monitoring
  • Self-tuning--no laptop or software required!

Now available as a Master Kit

Want to simplify both your shopping and installation process? Then opt for the Holley Sniper Master Kit! This kit includes virtually everything you will need to convert your carbureted fuel system over to one that will support your new Sniper EFI system: Inline fuel pump, filters, lines, fittings, and more. Adding this option means that there is no guessing, no additional shopping--get what you need right in the same box with your Sniper system, as paired by Holley's professional engineering staff.

NEW! Holley Sniper Laptop Tuning Software!

Pardon us as we struggle to contain our excitement about the newly released laptop tuning software exclusively for the Holley Sniper EFI Systems! Hey, what you can access and control via the included 3.5-inch touchscreen display is very impressive. This added software is not necessary for the vast majority of Sniper EFI users. But there are a few folks out there who wanted full-featured tuning capability. Well, here it is!

What can you do with the laptop software that you can't do with the handheld? Well, you can tune your Sniper to work with boosted engines up to 1 bar of boost (using the 2-bar map sensor that came on the Sniper.) It is important to note that this software deviates from the basic concept of EFI for Everyman. While it is easy to add the required USB Dongle, download the Sniper EFI Software, install, connect, and run, learning EFI tuning is challenging to say the least. But for only the cost of the dongle (the software is available at no cost) you can get started.  And we here at EFISystemPro.Com are excited to guide you in your learning.
