Nitrous Delay Timer: A digital timer is provided that can be used to delay the start of the nitrous.
This timer begins counting down when the activation terminal is on (+12v applied). If the activation signal is removed,
the delay timer will halt until the signal is re-applied. The delay timer can be programmed from 0.000 to 9.999
seconds.
Nitrous Starting Percentage: The user can program the amount of nitrous power that will
be applied after the nitrous delay timer has elapsed (Immediately if delay timer is set at 0.000). This parameter is set
as a percentage and can range from 10% to 100%. If the starting power is more than the ending power, the nitrous
power will decrease with time.
Final Nitrous Percentage: This setting allows the user to program how much nitrous power
is applied after the nitrous ramp has completed. This parameter is also set as a percentage and can range from 10%
to 100%. By setting the final power percentage less than the starting percentage, the user can back off the nitrous
power.
The Options Menu allows the user to select a single or dual ramp nitrous power ramp. When the dual ramp
mode is selected, there will be two final percents and two power ramp times.
Nitrous Power Ramp Time: The power ramp time is used to determine the rate at which
the nitrous power goes from the start percentage to the final percentage. The nitrous power ramp time can be set
from .200 to 9.900 seconds.
The Options Menu allows the user to select a single or dual ramp nitrous power ramp. When the dual ramp
mode is selected, there will be two final percents and two power ramp times.
Intelligent Nitrous Progressive Timer: The progressive nitrous timer system will wait
at its present state if the activation signal is removed. Nitrous progression will resume when the controller is re-
activated. The entire nitrous and +12 volt timer system is automatically reset 20 seconds after activation.
Optionally the nitrous timer system can be configured to RESET each time the activation signal is applied.
This method would allow the nitrous power to be applied with each gear change or each time the throttle is lifted and
re-applied. This feature is selected with the Options Menu.
An added feature has been included to the timer system to help the user tune the nitrous power ramp. When
the timer system is activated (+12v at the activation input) an internal timer is started which will record the time and
percent of the progressive cycle when the activation signal is removed. This data can be used to determine at what
point in the progressive cycle that the power ramp is too aggressive and the driver is lifting the throttle.
