the valid ranges shown above.
Hall Pull-Up Option
This option enables or disables a 4.7k Ohm pull-up resistor to +12V on the Hall Input terminal. This option is
normally used when connecting to the vehicle speed signal output from an ECM that is not connected to any
other systems or modules in the vehicle. On vehicles that already have this signal connected, a Pull-Up resistor
is normally already in the circuit. You DO NOT want to have multiple Pull-Up resistors in the circuit.
Access from the Controller:
From the Main screen press the “SETUP” button, press the “DOWN” arrow button repeatedly until the Hall Input
Menu is highlighted and then press the “ENTER” button. Press the "ENTER" button to select the "Hall Pull-up"
option, then the “YES” or “NO” button to change the current selection. If the “NO” button is pressed no change
will be made.
Access from the Computer Program:
From the
Status screen , press the "SETUP" button. The "Hall Input Pull-Up Resistor Enable" option is found
under the "Hall Input" tab. Click "ON" to enable the Hall Pull-Up resistor feature or "OFF" to disable the feature.
7.12 Fuel PSI Menu
The following options are found in the Fuel PSI Menu, which can be accessed by the "SETUP" button on the
main screen or by clicking the Fuel Sensor tab in the Setup menu of the computer software. The fuel pressure
menu allows the user to data log the fuel pressure in order to disable nitrous when necessary based on the
observed fuel pressure. By having fuel pressure input into the NCC-002, you can also use the relay outputs to
trigger an auxiliary fuel pump based on the desired fuel pressure.
