EFI System Intro

Introduction

Scope of this guide

The purpose of this guide is to guide you through the installation and basic setup of your EFI System. It covers the process from installation through initial start-up and includes essential troubleshooting steps to help you achieve a smooth, stable idle before moving on to driving.

This manual does not cover advanced setup, advanced drivability adjustments, or performance tuning. For diagrams, guides, videos, and expanded troubleshooting resources, please visit our resource center at acesefi.com, where you can also connect with our support team during business hours.

This EFI system is designed to be easy to use for first-time EFI users. These instructions are written with that in mind. They do not cover EFI theory in detail, but instead provide the steps needed to get the engine up and running quickly. The EFI  system also allows the user to make basic to very advanced tuning changes if desired.

Important Note

Depending on the type of kit you purchase, it may or may not include fuel system components such as the fuel pump, fuel filters, fuel pressure regulator, and fuel lines. Aces Fuel Injection offers complete kits, which can be purchased separately.
