Zipper's Performance 109-214 - Manual (Page 5)

DEFINITIONS:
1. Nitrous Enable/Disable - Enables (turns on)
or
disables (turns off) all nitrous
functions, regardless of other settings or switch
positions.
2. [Engine RPM] - Sets minimum rpm for
nitrous activation (maximum rpm remains
located in [BASIC SETTINGS] under [REV
LIMIT]).
3. [Vehicle Speed] - Minimum vehicle speed
for nitrous activation regardless of other settings.
4. [Fuel Enrichment] – Percentage of additional
fuel (global override) that is applied to the
installed base map fuel delivery during nitrous
activation. AFR’s for nitrous activation in the low
to mid 11's are safe. More power may be
available with a leaner mixture.
5. [Ignition Timing] - A flat value of spark
retard (global override) on nitrous activation.
6. [Delivery Delay] – Fuel and timing. Sets a
time delay due to solenoid opening and purging
of air in the system. Fuel enrichment and timing
adjustment are delayed by this number in
milliseconds after all other conditions are met.
Summary of Operation
The NADS system has only has 2 states,
"Active” or "Not Active". In order to go into the
active state all of the following conditions must
be met:
1. System must be "enabled" from nitrous menu
in TMax software. From the toolbar [Configure]
[MODULE Settings] [Nitrous] (requires module
link).
2. The arming switch, located on the rear
cylinder breather port, must be cycled from the
"disarmed" (switch light off) to the "armed"
position (switch light on) after the engine is
started.
If the switch was left in the “on” position
when ignition was cycled off, arming switch must
be cycled off / on before system will activate.
This
prevents accidentally causing an
inadvertent charge of Nitrous or activation on the
following ride.
Note - On some models, the check engine and
battery lamp will be lit together when the system
is armed to provide another visual reminder that
the system is in an active mode. This is normal
and intended.
3. Rpm must be above the target nitrous menu
rpm setting and below the prescribed rev limit.
4. Vehicle speed must be above the nitrous
menu vehicle speed setting.
Suggestions and Recommendations
The bottle is equipped with a valve that can be
opened or closed. We suggest closing the valve
when not in use. Extra bottles are available for
purchase to quickly replenish exhausted nitrous.
Change and vent bottles only in a well ventilated
area. When changing the bottle, close the bottle
valve before disconnecting the line. Slowly
loosen the line until a hissing sound is heard; let
the line pressure escape slowly. Do not inhale
nitrous as continued exposure can cause death.
Do not allow liquid nitrous to touch your skin as
it will burn like dry ice. Carefully check for leaks
any time a connection has been broken. Do not
use Teflon® tape on the tapered line fittings.
With a 12oz bottle, you can expect 3-4 full
throttle pulls per bottle. Degree of engine
modification and engine size will affect this
estimation.
When the available nitrous is used up and the
system remains enabled, The additional fuel
dictated by the active system will cause the
engine to run in a rich condition absent the
presence of available nitrous. Turn off the
arming switch to avoid overfueling the engine
when the nitrous runs out.
Conservative Settings
Lower fuel enrichment settings will increase
performance but will lean out the air/fuel ratio
Target air/fuel ratio while system is activated is
between 11.25 and 11.75
