DO NOT CHARGE THE BATTERY WITH A 24VOLT TRUCK
CHARGER OR REVERSE THE POLARITY OF THE BATTERY OR
ANY CHARGING UNIT
DO NOT CHANGE 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 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.
6) 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 use thermally conductive brackets where
appropriate.
7) We recommend having your system tuned by professionals. An exhaust gas analyser and
fuel pressure meter make tuning easier and help avoid potentially disastrous lean out
conditions that could destroy your engine. Should you wish to tune this unit yourself, make
sure you have some reliable means of determining if your engine is running lean. Haltech
offer the Haltuner for this very application. The Haltuner is an inexpensive air-fuel ratio
indicator that gives a full-scale deflection from rich to lean over a display of 30 bar segments.
It is compatible with all Oxygen Sensors that output a 0-1V and can be configured upon
request for other sensor ranges. If used in conjunction with a Haltech Oxygen Sensor, the
Haltuner will provide air-fuel indication for a range of 11.5:1 to 17:1.
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.
Tool/Supply Requirements
Installation of this system can be easily carried out by professional mechanics and most
experienced home mechanics if the following tools and components are available:
Voltmeter or Test Light
A selection of screwdrivers and spanners
Soldering Iron and solder (we recommend soldering all connections)
