Introduction


Congratulations on your decision to install a Haltech Engine Management System to your
vehicle. Haltech EFI systems have been successfully installed on thousands of vehicles, from
power off-shore boats to twin-turbo Ferraris, from pylon racing aircraft to jet skis and
snowmobiles. Over the past decade, many motorsport enthusiasts have discovered that the
Haltech computer is easy to use and gets the job done correctly - that job being to reliably
make a lot of horsepower and torque in an engine by enabling users to precisely control
ignition timing and fuel-air mixture. Precise ignition and 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 the easiest possible 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
supercar builders in the world use Haltech equipment for the same reasons that Haltech is
popular with motorsports 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 Overview


The Haltech E6K system utilises a special-purpose programmable microcomputer designed
for engine management. The E6K system includes the ECU, engine sensors, and a special
wiring harness to connect them, plus 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. Haltech systems provide electronic fuelling control. The engine must
already be configured with intake manifold and suitable injectors, a fuel rail with pressure
regulator, and a high-pressure pump. To control ignition timing, the ECU requires a fixed
trigger from a distributor, crank angle sensor, or cam angle sensor. 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 ignition and 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 "Maps" that instruct the ECU how to inject fuel and when to fire the spark
under different conditions. The programming software has been designed to be functional,
"friendly" and intuitively easy to use.
