MAXIMIZER-II rev A
b) Using a trigger signal from a coil - first determine how often it fires per revolution of
the crankshaft. The correct setting would be:
x1 for a waste-spark since it fires each revolution of the crankshaft
x2 for a full-sequential since it fires every other revolution.
MAP Present allows you to select whether or not you have the internal MAP sensor connected to the
intake manifold of your engine. If connected, you can use the Map cutoff feature as well as log the
MAP pressure. A check mark in the box tells the MAXIMIZER-II that the sensor is connected.
Ignition Retard #1 When allows you to select the mode of the internal ignition retard switch #1. When
‘Grounded’ indicates that the output is grounded when active. When, ‘Not Grounded’ indicates that
the ignition retard wire is floating or not grounded when active. If your system requires a 12-volt
trigger signal, refer to the wiring section or contact technical support.
Ignition Retard #2 When allows you to select the mode of the internal ignition retard switch #2.
Note: These outputs function like an internal switch that connects to ground. They can be configured
to open or close when active (0.5 amps max). To use this feature you will need an ignition system
with a timing retard function.
Nitrous Pressure Sensor Present
allows you to select whether or not you have the nitrous pressure
sensor connected to the MAXIMIZER-II. This feature allows you to use the automatic bottle heater
control as well as log your bottle pressure. A check mark in the box tells the MAXIMIZER-II that the
sensor is connected and enables the automatic bottle heater control.
Bottle Heater Target Pressure (only available if sensor present is checked) allows you to select the
target pressure that the bottle heater will try to maintain.
Note: The automatic bottle heater function can be enabled/disabled manually via the bottle heater
switch, however the controller will only enable the heater if there is sufficient pressure in the line. If
the pressure is too low, the status indicator (optional) will flash slowly – once per second – and the
heater will be disabled. The automatic bottle heater function DOES NOT require the MAXIMIZER-II to
be armed.
Idle allows you to set the TPS idle setting.
WOT allows you to set the TPS wide-open-throttle setting.
GPO #1 and GPO #2 sets the mode that the general-purpose outputs operate as.
STATUS LED – the output will turn on when ever the MAXIMIZER-II is ARMED. If there is a
fault, it will flash at 4 times per second. If your bottle pressure is too low and either the arm
switch or bottle heater enable switch is on, it will flash at once per second. The fault status
takes precedence over the bottle pressure status.
BOTTLE OPENER – the output will open the bottle whenever the MAXIMIZER-II is armed or
the bottle heater enable switch is on. This feature requires the optional remote bottle opener
control module and an electric bottle opener. It will close the bottle if both the arm switch and
bottle heater enable switch are off.
