Ignition Bypass Bypass signal compatible with some General Motors
ignition systems. This function allows the ignition system
to provide the spark at 10° BTDC at cranking speeds
(below 500rpm). This aids starting.
Staging Signal Logic output that indicates Staging conditions. If Staging is
selected, and the Staged injector are firing, this signal will
be high (5 volts), otherwise it will be low (~ 0 volts).
Tacho Output Used for driving tachometers when running a multicoil
ignition set-up. This output combines all of the multicoil
signals into one output and this is used to provide an RPM
measurement.
Ignition Toggle This output is used for rotary set-ups where both the
primary and secondary trailing ignition signals are
connected on the single channel. This minimises the
amount of outputs needed to run this engine configuration.
INJ x Current
The ECU has four injector outputs: INJ1-INJ4. These have the ability to drive up to
8A peak and 2A hold current through the injector load. The current control options
must be set properly for the number and type of injectors connected to the specific
output (INJ1-INJ4). The appropriate injector current control settings are further
described in the appendix
WARNING:
THE CURRENT CONTROL MUST BE SET CORRECTLTY.
EXCESSIVE CURRENT PASSED THROUGH AN INJECTOR LOAD
FOR A LONG PERIOD OF TIME MAY DAMAGE THE INJECTORS
4.2.5 Dual Map Set-Up
The ECU is capable of storing two sets of base fuel and base ignition maps. These two sets of
maps allow the user to map the ECU for different engine conditions such as:
- If a user wishes to use racing fuel on race day but standard pump fuel map
can be tuned for a specific fuel.
- Vehicles that have variable valve timing and/or lift require different
fuelling at the same load and rpm point for different valve timing and lift
positions.
The dual map set-up pages have the following fields:
Currently Editing
This field allows the user to select which set of fuel and ignition maps they wish to
edit. This field has the following options:
Primary Map
This selects the primary maps for editing.
Secondary Map This selects the secondary maps for editing
Use of Secondary Map
This defines the method by which the ECU determines which base map to use. The
options are:
