4.2.1 Main set-up Page
The main set-up page contains basic engine information. The Main Set-up Page is accessed
via the set-up menu or using: CTRL-M from anywhere in the programming software.
The fields in the main set-up page are as follows:
Cylinders
The number of cylinders needs to be entered here. This parameter is used to determine
the engine speed and other fuel and ignition requirements.
Load Sensing
The ECU can use either the manifold pressure or the throttle position as a means of
determining the engine load. Most engines operate using manifold pressure to sense
engine load. If your engine employs any form of supercharging, you must run in
manifold pressure mode. Only engine with long duration cams or multiple throttle
bodies, motorbikes or heavily ported rotaries require throttle mode - i.e. Engines
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 E6X will resume normal fuel or ignition
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.
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 since the unburnt fuel can
damage the catalytic converter.
Units
The programming software can display parameters in either Metric or US units.
RPM Mode
The ECU fuel and ignition 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 and ignition Maps, and will change the tuning of the engine dramatically.
