RPM Limit Type
The RPM Limit can either be a fuel cut or an ignition cut. This field determines what
form of limit will be used. Be careful using an ignition cut on an engine with a
catalytic converter, as the unburnt fuel can damage it.
Units
The Haltech E6H/E6M programming software can display parameters in either Metric
or US units.
RPM Mode
The E6H/E6M fuel and 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
unless necessary.
Road Speed Value
This value calibrates the Road Speed reading. Some applications in Advanced Mode
cannot use the Road Speed input trigger, and this field will not be displayed.
System Mode
This field sets the operating mode for the software. The software can be used in either
Basic or Advanced Mode. Most installations will only require the Basic Mode. To
determine if you need to use the Advance Mode, see the Introduction.
