GENERAL APPLICATION:
12-volt DC negative (-) ground electrical systems (11-20 VDC
operating voltage range).
The upper rpm limit of the shift light is variable, dependent upon the
PPR setting. The upper RPM limit for the PPR settings are .5-2 PPR=
18,000 RPM, 2.5-4 PPR= 15,000 RPM, and 5-6 PPR= 13,000 RPM.
Programmable RPM dependent switched output that will sink
(ground) 1 amp maximum (short circuit protected).

SHIFT-LIGHT MOUNTING:
The Ultra-Shift Light may be mounted on a roll cage, steering
column, dash, or other locations of high visibility.
To mount the
Ultra-Shift Light , use the bracket and screws provided,
or secure using a hose clamp.
To mount on an existing tachometer, loosen the mounting strap and
insert the base of the
Ultra-Shift Light bracket under strap and
retighten the mounting strap.
SHIFT-LIGHT WIRING (FIGURE 1):
1. Disconnect negative (-) battery cable.
2. Using 18-ga. wire, connect the (BLACK) wire to a clean (rust/paint-
free) ground, preferably battery negative terminal.
3. Using 18-ga. wire, connect the (RED) wire to a switched +12V
source, like the ignition wire.
4. Using 18-ga. wire, connect the (GREEN) wire the coil negative or
the tachometer terminal of the ignition module.
5. Using 18-ga. wire, connect the (WHITE) wire to the relay coil
negative. This wire will supply the ground (1 amp maximum) to
energize the relay and activate the desired device.
NOTE: The (WHITE) wire provides an output (switched to ground)
whenever the engine RPM is between the programmable L0 and HI
set points. This switch can be used to activate/deactivate any device
within a specific RPM range.
WARNING: Always use an, in-circuit
“Arming” switch to disable any
device controlled by the RPM window switch. In addition to the
“Arming” switch, a wide-open-throttle switch MUST also be used
to deactivate a nitrous oxide, or similar system, when the engine is
no longer at wide-open-throttle.
6. Reconnect the negative (-) battery.

ULTRA-SHIFT WITH RPM WINDOW SWITCH OPERATION:
Once the Ultra-Shift Light™ with RPM Window Switch is installed and
set up, the digital display, if Disp option is set to 0n, will show the
actual engine RPM, otherwise the display will be blank.
The peak RPM recall may be viewed at anytime during normal
operation. The peak RPM value is the maximum RPM attained since
the last time the peak was cleared.
1. At any time during normal operation, display the max RPM
recall by pressing the
SCROLL button.
2. The internal display will show PEAC then display the peak RPM.
3. To clear the stored peak value, press and hold the
SCROLL
button. The display will read PEAC then display the peak RPM,
and then return to normal operation.
The shift indicator LED cluster will illuminate whenever the engine
RPM exceeds the programmable SHP RPM setting (refer to the Shift
RPM Setup section for programming information).
The shift indicator LED cluster brightness may be changed to one of
four levels at anytime during normal operation. These are used to
adjust to the changing racing conditions for the best visibility.
1. To change the intensity of the LED cluster, press and hold
SELECT button. The LED cluster will rotate through the four
levels.
2. To select an intensity level, simply release the
SELECT button
when the LED cluster is at the desired intensity.
The switched output (WHITE) wire will switch to ground whenever
the engine RPM is between the programmable L0 and HI set points,
otherwise the output is off or floating (refer to the Window Switch
section programming and circuit wiring information). The switched
output may be used to control most any device where engine RPM is
a factor used to turn a device on or off, such as Nitrous Oxide
systems, CO2 and water sprayers for intercoolers, or even automatic
shifters.

SET-UP MENU, OPTIONS, & DESCRIPTIONS:
The Set-up Menu sets the different options and calibrations to establish
the overall operation of the Ultra-Shift Light™, and should be set up
before the RPM window switch option is used.
ShP – Sets shift point RPM.
NOTE: The upper rpm limit of the shift light is variable, and depends
upon the PPR setting. The upper RPM limit for the PPR settings are
.5-2 PPR= 18,000 RPM, 2.5-4 PPR= 15,000 RPM, and 5-6 PPR=
13,000 RPM.
Disp – Display options (0n, 0ff). This determines the information
shown on the display.
•0n - Current engine RPM is shown on the display.
•0ff - Nothing displayed. Recall information can still be viewed.
ppr – Pulses/revolution of the tach signal (.5,1,1.5, 2, 2.5, 3, 4, 5, 6).
WARNING: An improper PPR setting will cause the RPM display, shift
light activation, and switch activation to be inaccurate.
L0 – Set switched output activation RPM (Range: 500 to18.00).
HI – Set switched output deactivation RPM (Range: l0 setting
to18.00).

1. Enter programming mode by pressing both SCROLL & SELECT
buttons at the same time, and then release both buttons.
2. Scroll to the SHP parameter using the
SCROLL button, and then
press the
SELECT button.
3. The display will show the current shift point RPM (the default is 3000
RPM for a new shift light).
4. Hold down the
SCROLL button to increment slowly. After holding
down for one second, the value will increment quickly. Simply
release the
SCROLL button and press it again to go back to
incrementing slowly. Press the
SCROLL button repeatedly to
increment one step (10 RPM) at a time. If the desired shift RPM is
missed simply continue to hold the
SCROLL button and the value
will wrap around and start at 1000 RPM again.
NOTE: When scrolling above 9990 RPM, a decimal point will appear in
the center of the display to indicate that the far right digit will not be
displayed (refer to figure 2).
5. Once the desired shift RPM is displayed, press the
SELECT button to
return to the
MAIN MENU .
6. To exit programming mode, do not press any buttons for 5 seconds.
All changes will automatically store and the unit will return to normal
operation.
NOTE: The upper rpm limit of the shift light is variable, and depends
upon the PPR setting. The upper RPM limit for the PPR settings are
0.5-2 PPR= 18,000 RPM, 2.5-4 PPR= 15,000 RPM, and
5-6 PPR= 13,000 RPM.

PPR SET-UP (.5,1,1.5,2,2.5,3,4,5,6 PPR):
WARNING: An improper PPR setting will cause the RPM display, shift
light activation, and switch activation to be inaccurate.
1. Enter programming mode by pressing both
SCROLL & SELECT
buttons at the same time, and then release both buttons.
2. Scroll to the PPr parameter using the
SCROLL button, and then
press the
SELECT button.
3. The display will show the current setting (the default setting for a
new unit is 4PPR).
4. Press the
SCROLL button to change the setting.
5. Once the desired setting is displayed, press the
SELECT button to
return to the
MAIN MENU .
6. To exit programming mode, do not press any buttons for 5 seconds.
All changes will automatically be stored and the unit will return to
normal operation.
TIP: When connecting to an engine with a distributor, generally, the old
rule, half the number of cylinders = PPR, still applies. When
connecting to the signal wire to a coil pack that drives 2 cylinders,
generally, the PPR = 1. When connecting to a “coil on plug” ignition
or one coil for each cylinder, the best option is to look for a tach
signal coming out of the ECU, but the .5 PPR setting may work when
directly connected to any one of the coils. If this connection is erratic
or does not function correctly, a tachometer adapter may be
required. Call technical support a 1-866-797-7223 or visit
www.SW-Performance.com for more information.

NITROUS OXIDE SYSTEM CONTROL WIRING:
¾The switched output is very useful for controlling Nitrous Oxide
activation/deactivation. Set the programmable L0 value to the
desired engine RPM where the device activates and the HI value to
the desired RPM where the device to deactivate (usually just before
the engine rev limiter triggers to prevent catastrophic engine
damage).
¾Wire the Nitrous Oxide System, as illustrated below, using the
supplied relay and the
“Arming” and “Wide-Open-Throttle”
switch supplied with the Nitrous Oxide System.
¾The
“Arming” switch will deactivate the system so it can’t be
activated unexpectedly. The
“Wide-Open-Throttle” switch will
only allow activation when the throttle is wide open, so the system
will shut down during shifts or deceleration, even if the engine RPM
is still in the activation range.
10
INTERCOOLER SPRAYER CONTROL WIRING:
¾The RPM switched output, when used in conjunction with a pressure
switch is very efficient at controlling an intercooler CO2 or water
sprayer system during high boost and high engine RPM when the
efficiency of the intercooler falls off. This set-up works well to
conserve the CO2 or water supply for when it’s needed most.
¾The pressure switch is used to activate the system only when the
boost pressure is high.
¾The RPM switch is used to control the RPM at which the system is
activated so the system does not activate at low RPM when the
intercooler can easily cool the lower airflow.
