Haltech F10 - Manual (Page 6)

Introduction
Congratulations on your decision to install a Haltech Engine M anagement 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.
M any 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 professional racers and super-car builders in the
world use Haltech equipment for the same reasons that Haltech is popular with performance
enthusiasts: it is flexible and friendly; is installed easily; and you can tune your Haltech
simply, without having to make the project a major research effort.
Installation Overvie w
The Haltech F10 system uses a special-purpose programmable microcomputer designed for
engine management. The F10 system includes the ECU, engine sensors, a special wiring
harness to connect them, programming 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 wiring 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 be
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, you tune it by connecting the ECU to an IBM compatible
PC via the supplied communications cable. The Haltech Programming software allows you to
configure and modify the fuelling data stored in the ECU: it's as simple as adjusting 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 comes to start your engine, the base fuel map already loaded in the system
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 your Haltech system far easier than
tuning a carburettor or mechanical injection system, and with much better results.
