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.
Before You Begin...
1) IT IS BEST TO READ THIS ENTIRE MANUAL BEFORE STARTING.
At the very least, you should read Section One of the manual, and any of the Appendices that
are relevant to your installation. The greater your knowledge of the operation of the Haltech
system, the easier you will find it to understand what you are doing, and why.
2) Read any additional material accompanying this manual that updates the document since it
was written.
3) You may need special parts or additional tools or test equipment in order to complete
installation. Make sure you have these items on hand before you begin to avoid frustration.
Contact your Haltech dealer if you have difficulty.
4) Don't do the minimum work possible. Carelessness in the early stages of installation can
cause you major headaches later on, be it in a few days' or a few months' time. Carelessness
will cost you money and frustration in finding and fixing unnecessary problems. You have the
opportunity to make sure your Haltech system's operation is extremely dependable and easy to
use by doing it right the first time.
There is another reason to exercise care during this installation. You will be dealing with
explosive fuel under pressure, electricity and considerable heat. Inside the combustion
chamber, this is a happy combination. In the garage, they are not. The same kind of danger
exists when working underneath a jacked-up car. Please be careful.
Avoid open sparks, flames, or operation of electrical devices near flammable
substances.
Always disconnect the Battery cables when doing electrical work on your vehicle.
All fuel system components and wiring should be mounted away from heat sources,
shielded if necessary, and well vented.
Make sure there are no leaks in the fuel system and that all connections are
secure.
Disconnect the Haltech ECU from the electrical system whenever doing any arc
welding on the vehicle by unplugging the wiring harness connector from the ECU.
5) Electromagnetic interference (EMI) from unsuppressed spark plugs and leads can cause the
ECU to fail. Please do not use them.
