Converting an older vehicle to electronic fuel injection can be the best way to get the most out of its engine, especially if the engine itself is not the OEM design. Crate engines and rebuilds with performance enhancements both benefit from the precision of an EFI, and the Holley Sniper EFI 2 offers self-tuning and other benefits that make it and easy conversion kit for you and your wallet to manage.

An EFI System That Learns

The advantage to Holley's flagship conversion system is the ability to self-tune once properly installed. The entire kit is designed to make the job simple by working with as much of the original fuel system as possible, and the electronics support that ethic as well. Not only does the ECM adapt on the fly to give you the best performance possible under changing conditions, it also learns on its own from your engine without a lengthy manual fine-tuning phase.

A Built-in ECM That Simplifies Installation

Since the Sniper 2 design includes a throttle body-mounted ECM in its design, you do not need to order a separate control module or worry about finding a place in your engine compartment to mount it. This allows Holley to use an ECM designed to work with the rest of the system for greater efficiency and simplifies your installation when you convert from a carburetor to an EFI system.

This powerful ECM supports multiple profiles and allows you to get engine feedback or change profiles via an installed display controller that is part of the system. This controller is also what you will use to run the self-tuning operation. Installation of the Sniper 2 throttle body will require you to hook up the electronics for the ECM, though, so it's a good idea to have a color code GM steering column wiring diagram and the other tools you need to understand how that installation will affect the electronics on the rest of the car and where to patch it in.

Advances Over Earlier Designs

Holley's original EFI conversion set new standards for performance and ease of use that affected the design of other systems after it. The Sniper 2 system continues this tradition by building on Holley's own designs with improvements that continue to prioritize a simple-to-install, reliable, and powerful EFI conversion. That means a design that requires as few additional fitments as possible. The Sniper 2 EFI does not need a return line, and revisions to the original design make it work directly with the linkages of even more vehicle designs across more automakers.

Handling That Matches Your Power

If you do make the conversion to an EFI to unleash more engine power, you might need to upgrade your brakes and tires to make the most of this increase in performance. The right drag tires can deliver traction and control that allow you to put that power and acceleration to use with better efficiency and precision. A balanced approach not only gives you a more enjoyable driving experience, it also helps you stay safe. Start looking at tire upgrades to go with your new EFI today.
