The NOS Mini 2-Stage Progressive Nitrous Controller accepts most
tach signals, including low-voltage and irregular signals, such as
those found on many V-10s. Each channel will drive a fuel or nitrous
solenoid progressively. The Throttle Position Activation Switch
(TPAS) accepts all analog throttle position sensor signals as well as
a “hot” or “grounded” wide-open-throttle (WOT) switch. Both
channels have their own programmable parameters, as well as their
own control output for triggering extra functions, such as ignition
retard. Each channel’s internal TPAS can be configured to prevent it
from activating, unless you are at WOT. Solenoid pulse frequency is
also adjustable to allow the use of different types of solenoids.
Proper grounding is essential to a microprocessor controlled
progressive nitrous controller. The controller has two ground wires
that need to be connected. Proper practice is as follows:
Ground #1 – 12 AWG black ground cable – Install this to a good
chassis ground that is grounded securely to the battery as well.
Ground #2 – 18 AWG black ground wire – Install this to a “CLEAN”
ground point in the vehicle.
IMPORTANT! A “clean” ground is a ground point that does not
have “dirty” ground attached directly to that point. “Dirty” ground
items consist of any ignition product as well as the 12 AWG black
ground cable from the controller. “Clean” grounds are grounds that
go to sensors or other microprocessor controlled devices. Do NOT
“stack” clean grounds to the same stud/ground point that you attach
“dirty” ground wires to. It is acceptable to run a single ground cable
from the battery to a ground buss bar (multiple ground studs). Stack
“dirty” grounds to one point/stud and attach “clean” grounds to a
separate point/stud.
1. Connect the main 8-pin wiring harness to the controller.
2. Connect the WHITE wire to a +12V fused switched power
source. You should install this to a circuit that has a 5A fuse and
