How It Works
The Haltech IG5 uses a digital microcomputer to measure engine speed and load and uses these
values to access a look-up table of ignition advance (°BTDC). This look-up table is called a base
ignition map and is stored in non-volatile memory (i.e. memory which is retained when power is
switched off). Programming software allows the contents of this memory to be changed to match
the requirements of the engine.
The Features of the IG5
The IG5 is designed to be easily programmed and is capable of being used on a wide variety of
applications. A typical IG5 installation could be 4, 6 or 8 cylinders, turbo/supercharged or
normally aspirated, distributed ignition (only one ignition output) or Direct Fire ignition (multiple
ignition coils). It will also provide the ability to control some other features, such as Turbo
Wastegate Control, Thermofans, Torque Converter Clutch Lockup, etc.
Note: You should read Appendix B & C before you install the system to be
fully aware of your hardware and installation requirements.
The following variants are catered for by the Haltech IG5 system
Direct Fire Ignition
Rotary Engines
Twin Triggers
Twin Distributors
Multitooth Trigger Systems
The above will be determined by your engine configuration. If your engine has no distributor, for
example, you will need to use Direct Fire. All the features will be determined by your engine set-
up.
