Haltech IG5 - Manual (Page 27)

23
Units
The Haltech IG5 programming software can display parameters in either Metric or US
units.
RPM Mode
The IG5 ignition maps may be arranged either in 500 rpm increments to 10,500 rpm,
or in 1000 rpm increments to 16,000 rpm. Select the high - or low - rpm mode here.
Changing settings alters the way the ECU reads the Maps, and will change the tuning
of the engine dramatically. Do not change this setting once tuned.
Road Speed Value
This value calibrates the Road Speed reading. Some configurations cannot use the
Road Speed input trigger in which case this field will not be displayed.
Trim Control
The optional Trim unit can be used to control one of several parameters. This field
selects the controlled parameter. If there is nothing connected to the trim plug, the
trim will have no effect (except with boost control). The available functions are :
Ignition +7 to -8 degrees adjustment of ignition advance.
Ign Trailing +7 to -8° adjustment for Rotaries only
Boost Control Boost trim for Wastegate control only.
Aux. In Function
The Auxiliary Input on the IG5 can be configured for one of a number of functions.
Most of these functions relate to the configuration of the system. The available
functions are:
Disabled No effect on ECU operation.
Nos Input
Input - This input is used in conjunction with the
Nos Optional Output. [13.10]
TCC Input
Input - This input is used in conjunction with the
TCC Optional Output. [13.4]
Turbo Timer
Input - This input is used in conjunction with the
Turbo Timer Optional Output. [13.9]
Since the Auxiliary Input line can only perform one duty, all of the above functions are
mutually exclusive, i.e. although four programmable outputs exist on the IG5, only one of the
NOS, TCC and Turbo Timer may be chosen. Keep this function in mind when deciding on
the IG5 configuration you wish to run.
3.2 Ignition Set-up
The Ignition Set-up works in an similar way to Engine Identification. Its fields relate to the
way the ignition advance is determined for the engine. Enter the Ignition Set-up by pressing
