Haltech E8 - Manual (Page 7)

Haltech E11/E8 Instruction Manual
Electromagnetic interference (EMI) from unsuppressed spark plugs and high tension leads can cause the
ECU to fail. Please do not use them.
In hot climates, or with turbocharged engines, you may need to employ heat shielding to prevent heat
soak and damage to electrical and fuel parts. Use the coolest surfaces of the chassis as a heat sink for
components and shield any wiring that may be affected by heat.
We recommend having your system tuned by a Haltech Dealer or by a Workshop that has the proper
tuning equipment like exhaust gas analyser, fuel pressure meter, Dynamometer etc. Otherwise trying to
guess or tune by ear can lead to disastrous lean out conditions that could destroy your engine.
Note: In this manual, reference will be made to MAP (Manifold Absolute Pressure - as in MAP sensor) and
the fuel maps stored in the ECU. Both are common industry terms, with entirely different meanings.

WARNING
Avoid open sparks, flames or operation of electrical devices near flammable
substances. Always disconnect the battery cables when doing electrical work on
your vehicle.
Do not charge the battery with a 24 Volt truck charger or reverse the polarity of
the battery or any charging unit. Do not charge the battery with the engine
running as this could expose the ECU to an unregulated power supply that could
destroy the ECU and other electrical equipment.
All fuel system components and wiring should be mounted away from heat
sources, shielded if necessary and well ventilated. 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.
After completing the installation, make sure that there are no fuel leaks, and no
wiring left un-insulated in case a spark or short-circuit occurs and causes a fire.
Also make sure that you follow all proper workshop safety procedures. If you're
working underneath a jacked-up car, always use safety stands!
