Haltech IG5 - Manual (Page 7)

3
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) IGNITION MODULES It is essential that the user fully understands what type of ignition
module (igniter) is to be used with the Haltech ECU. Constant charge and constant duty igniters
are available and the ignition set-up page must be set accordingly before power is applied and the
ignition modules are connected to the main loom. Failure to do so may damage the igniters and
coils.
Constant Duty is used with “Intelligent” igniters such as the Haltech supplied EB023. Constant
Charge is used with “Dumb” igniters that can also be obtained from Haltech as single, double or
triple igniters.
Most standard OEM supplied igniters are of the “dumb” type but if in any doubt it is necessary to
check or purchase suitable igniters through your Haltech supplier.
WARNING:
HALTECH WILL NOT REPLACE ANY IGNITION COMPONENTS
DAMAGED BY FAILURE TO COMPLY WITH THE ABOVE
PROCEDURES.
Previously Haltech ECU’s were only compatible with constant duty type igniters; therefore
numerous references are made to the EB023 BOSCH module which is supplied by Haltech.
Haltech can supply both constant duty and constant charge modules to suit the IG5. Many of the
modules have a similar external appearance and it is essential that the installer be able to identify
the unit as constant charge or constant duty.
Note: In this manual, reference will be made to a MAP sensor (Manifold
Absolute Pressure sensor) and the ignition maps that are tables stored in the
ECU. Both are common industry terms but 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)
