 (TPS) and 

wide-open-

throttle

 (WOT) switches.

Grounding these inputs is considered the “ON” position. They can be used to enable or disable 
individual stages. See configuration section for more details.

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.

These outputs can be used to retard timing provided that your ignition system supports this feature. 
They function like an internal switch that is either open or 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.
