The following appendices provide additional information to help clarify which settings to use for your application.
A glossary of selected terms can also be found to provide a better understanding of concepts related to the
NCC-002 nitrous controller.
9.1 Appendix A: Pulse Frequency Detailed Explanation
The Pulse Frequency is the number of times per second (Hertz of Hz) the solenoids are turned ON/OFF. This
frequency can be adjusted to one of three values--12.5, 20, and 25 pulses per second.
When the pulse frequency is changed the Nitrous and Fuel Progressive Ramps should be checked. The reason
for this is the way the NCC-002 stores the data. For example a setting of 12.5 Hertz generates fewer data points
over a given time interval than the 25 Hz setting 12.5 pulses per second vs. 25 pulses per second).
When going from a lower frequency setting to the 25 Hertz frequency setting, the total time in seconds for the
Progressive Ramp is decreased. This change in time does NOT effect the Main Timer Timeout period in any
way. The last Percentage setting of the Progressive Ramp is used for the remainder on the Main Timer period.
See Appendix B for more information.
The best way to learn more about this feature is to change pulse frequency and then use the “Nitrous Graph
Setup” to navigate the Progressive Ramp and view the time change per pulse in the Graph Setup screen.
