Introduction

Congratulations on your decision to install a Haltech Engine Management System on your

vehicle. Haltech EFI systems have been successfully installed on thousands of vehicles such

as power offshore boats, twin-turbo Ferraris, pylon racing aircraft, jet skis and snowmobiles.

Many motor sport enthusiasts have discovered that the Haltech computer is easy to use and

gets the job done correctly. The Haltech ECU enables you to precisely control fuel-air

mixtures that lead to consistent horsepower and torque from an engine. Precise mixture

control also leads to excellent drivability and fuel economy, something that is often lacking in

high-performance carburettor engines.

Haltech users have discovered that the flexibility of the Haltech Electronic Control Unit

(ECU) and PC based programming software leads to easy installation on everything from

traditional pushrod V8s to high performance turbocharged racing motorcycles. We are proud

of the fact that some of the most respected p rofessional racers and super-car builders in the

world use Haltech equip ment for the same reasons that Haltech is p op ular with p erformance

enthusiasts: it is flexible and friendly; is installed easily ; and y ou can tune y our Haltech

simply, without having to make the project a major research effort.

Installation Overview

The Haltech F10 sy stem uses a sp ecial-purpose p rogrammable microcomp uter designed for

engine management. The F10 system includes the ECU, engine sensors, a special wiring

harness to connect them, p rogrammin g software and cable for you to tune the system. In the

course of the installation, you will mount four electronic engine sensors, two for temperature,

one for throttle position, and one to sense vacuum/pressure. You will run the wirin g harness

through the vehicle, connecting the 12V, ground and signal wires, and plug the harness

connectors into the engine sensors and fuel injectors. An ignition output module will b e

mounted in the engine bay and connected to the harness. Finally, you will mount and connect

the ECU itself. The engine must already be configured with intake manifold and suitable

injectors, a fuel rail with pressure regulator, and a high-pressure pump. If your vehicle lacks

one or more of these components, your Haltech dealer can help you obtain them.

With the Haltech system installed, y ou tune it by connecting the ECU to an IBM comp atible

PC via the supp lied communications cable. The Haltech Pro grammin g software allows you to

configure and modify the fuelling data stored in the ECU: it's as simp le as adjustin g the

heights of the bar graphs displayed on your PC screen. Collectively, the bar graphs form the

"M aps" that instruct the ECU how to inject fuel under different conditions. The programming

software has been designed to be functional, "friendly" and intuitively easy to use.

When the time co mes to start your engine, the base fuel map already lo aded in the sy stem

could get you going immediately, if not, a little alteration with some assistance from this

manual should get your vehicle running. Once the engine is running it is time to work on

fine-tuning your maps to suit your engine exactly, an air-fuel ratio meter and a dyno make

tuning easiest, but many people use the traditional method of "seat of the pants" feel and

tuning by ear, possibly checking spark plug colour as an indication of fuel mixture.

Whichever method you use, you will find that the ability to instantly change mixtures by the

stroke of a key, or the twist of a knob, will make tuning y our Haltech system far easier than

tuning a carburettor or mechanical injection system, and with much better results.
