These outputs can be used to turn on an LED or small panel lamp (0.5 amps max), automatically
activate your remote bottle-opener, or automatically purge your nitrous line. They function like an
internal switch that is open when not active and connected to ground when active. See configuration
section for more details.

Grounding this input is considered the “ENABLE” position for the automatic bottle heater control. This
feature allows the MAXIMIZER-II to control the bottle heater relay in an attempt to maintain the target
pressure. See configuration section for more details.

The MAXIMIZER-II has an integrated 48 psi pressure sensor designed to measure manifold absolute
pressure (MAP). Connect the flexible hose to your intake manifold after the throttle plate.
Note: The MAXIMIZER-II calibrates the sensor at power up. If your engine is running, the sensor’s
pressure reading will be outside the expected range and will not be calibrated – which may result in
an inaccurate reading. This is why it is recommended to connect the MAXIMIZER-II’s power to your
ignition switch.
