whose vacuum signal is small, or fluctuates greatly. If you are unsure what to use,
contact your Haltech dealer.
MAP Sensor
The ECU needs to know the type of Manifold Absolute Pressure (MAP) sensor being
used. If you do not know what sensor you have refer to 1.3.1 Manifold Absolute
Pressure (MAP) Sensor, p12. Enter the correct description here to match. If using
throttle position mode, set this parameter to a 1 Bar sensor.
RPM Limit
The ECU can limit the maximum rpm at which the engine will operate. Above this
level the ECU completely cuts fuel or ignition (see below) to the engine. When the
engine speed drops below the RPM Limit the F10X will resume normal fuel delivery.
This is known as hard limiting. If the RPM Limit is not needed then set this value
above the highest operating point of the engine.
Road Speed Value
This value calibrates the Road Speed reading. The value represents the number of
pulses received from the road-speed sensor over a distance of 1 km.
Rotary/Cylinder mode
This allows the user to choose between whether they are running a rotary or cylinder
mode.
RPM Limit Type
The RPM Limit can only be set to fuel cut for this unit.
Units
The programming software can display parameters in either Metric or US units. At
present HalwinX is fixed to SI units.
RPM Mode
The ECU fuel maps may be arranged either in 500 rpm increments from 0 rpm to
10,500 rpm, or in 1000 rpm increments from 0 rpm to 16,000 rpm. Select the high or
low rpm mode here. Changing this setting alters the way the ECU reads the fuel
Maps, and will change the tuning of the engine dramatically.
ECU Mode
The user has the option to choose between basic and advanced mode. This is a legacy
component from the DOS software and the user is advised to choose advanced mode.
Dual Map Setup
This allows the user to switch between Fuel map 1 and Fuel map 2. If Dual Map
disable is selected, Fuel map 1 is selected.
Use of Secondary Map
This defines the method by which the ECU determines which base map to use. The
options are:
Never
This causes the ECU to only use the primary base fuel
map.
