Dynojet Research, Inc. (Dynojet) makes no representation or warranties with respect to the contents
hereof and specifically disclaims any implied warranties of merchantability for any particular purpose.
Dynojet reserves the right to revise this publication and to make changes from time to time in the
content hereof without obligation of Dynojet to notify any person of such revision or changes.
Dynojet is not responsible for false operation due to unexpected dynamometer operation such as may
be caused by static, software bugs, hardware failure, etc.
Dynojet is not responsible for damage resulting from improper installation of the dynamometer or
from improper service rendered to the dynamometer. Dynojet is not responsible for damage incurred
due to alteration of the dynamometer or components, use of unapproved parts, or abuse to the
dynamometer.

WARNINGS
Electrostatic Discharge Precautions
Electrostatic Discharge
Electrostatic Discharge (ESD), or static shock, can damage electronic components within the
dynamometer. The damage may occur at the time of an ESD occurrence, or the shock may degrade the
component, resulting in a premature component failure later. To avoid ESD damage, always practice
good ESD control precautions when servicing the dynamometer. Dynojet designs its dynamometers
to be very tolerant of static shocks by the users, but the electronics are vulnerable when the electronics
areexposed.ESDoccursasaresultofadifferenceofpotentialbetweentwoobjectswhenthetwoobjects
touch. Damage occurs as a result of the energy released when the discharge (touch) occurs. The
difference of potential can accumulate by as simple an action as a user moving across carpet or a seat.
If that person’s energy is discharged directly to the electronics, the electronics can be damaged.
Precautions
To protect against ESD damage, you must eliminate the difference of potential before the electronics
arehandled.Touch thechassisofthe dynamometerbeforetouchinganyoftheelectronics.Bytouching
the chassis, you discharge any static shocks to the chassis instead of to the electronics.
If you are holding a circuit board or dynamometer component in your hand when you approach the
machine, touch the chassis of the dynamometer with your hand before installing the circuit board or
component.
When handing a circuit board or component to someone, touch that person with your hand first, then
hand them the component.
Always carry circuit boards in anti-static bags when the boards are exposed (removed from the
dynamometer).
Battery Fire and Explosion Hazards
There is a danger of explosion if the battery is incorrectly replaced. Replace only with the same or
equivalent type recommended by the manufacturer. Discard used batteries according to the
manufacturer’s instructions.
Automotive Batteries
In operation, batteries generate and release flammable hydrogen gas. They must always be assumed
to contain this gas which, if ignited by burning cigarette, naked flame or spark, may cause battery
explosion with dispersion of casing fragments and corrosive liquid electrolyte. Carefully follow
manufacturer's instructions for installation and service. Keep away all sources of gas ignition and do
not allow metallic articles to simultaneously contact the negative and positive terminals of a battery.
Do not allow the positive and negative terminals to short-circuit. The dynamometer chassis is tied to
the negative side of the battery. Do not short between the positive battery terminal or the starter
connections to the chassis. In addition, make sure metal tools such as screw drivers, wrenches, and
torque wrenches do not come in contact with the negative and positive terminals of the battery. Short
circuiting the terminals of the battery can cause burn injuries, damage to the dynamometer, or trigger
explosions.
Charging
Batteries being charged will generate and release flammable hydrogen gas. Charging space should be
ventilated.Keepbatteryventcapsinposition.Prohibitsmokingandavoidcreationofflamesandsparks
nearby.
Wear protective clothing, eye and face protection, when charging or handling batteries.

Verify brake operation before beginning any dynamometer testing.
Verify the vehicle is properly secured to the dynamometer.
Verify the vehicle is properly grounded to the dynamometer.
Never operate the blowers without the guards installed.
Exercise care with any dynamometer testing; portions of the dynamometer and vehicle may become
hot.
As with any equipment using electricity and having moving parts, there are potential hazards. To use
this dynamometer safely, the operator should become familiar with the instructions for operation of
the dynamometer and always exercise care when using it.
Do not repair or replace any part of the dynamometer or attempt any servicing unless specifically
recommended in published user-repair instructions that you understand and have the skills to carry
out.

SPECIFICATIONS AND OPERATING REQUIREMENTS
Introduction
Version 2 Model SD12 Scooter Dynamometer Installation Guide
YOUR DYNO ROOM
This section is not meant to imply that a dyno room is essential to repeatable results
on a Dynojet dynamometer. However, a dyno room with an engine cooling intake fan,
exhaust extraction, and noise reduction capabilities can add a new dimension to your
shop.
A proper dyno room design will help to ensure repeatable, accurate runs. A good dyno
room should do the following:
• minimize noise
• provide a controlled environment for testing
• provide a view window (safety glass) for customers
• be designed with safety in mind
Intake Air Fan—After building your dyno room, you will need to supply an intake air
fan. The intake air fan supplies air to cool the bike’s engine while supplying fresh
oxygen for you and your bike to breathe. It is a common misconception that you
cannot tune a bike without a large fan simulating exact road conditions; however, a
good cooling fan is the only requirement for consistent diagnostics and tuning. The
installed fan should be 5200 CFM.
Equalizer Box—If the air flow rate coming into the dyno room is greater than the air
flow rate leaving the dyno room, the room will become pressurized. A pressurized
dyno room will make measured power misleading. To compensate, you need an
equalizer box. The equalizer box is a baffled (to reduce noise) vent to the outside of
your dyno room. The size of the equalizer box is dependent on the size of your dyno
room and the size of your fans.
Exhaust Extraction—An exhaust fan is needed to remove exhaust gasses, especially
carbon monoxide, from the dyno room. Carbon monoxide is potentially lethal to
people if not removed from the room and will affect engine power when mixed with
fresh air. Plans for exhaust extraction (P/N 73429201) are available from Dynojet.
Engine exhaust contains poisonous carbon monoxide gas. Breathing it
could cause death. Operate machine in well ventilated area.
Fire Suppression—Always have adequate fire suppression or fire extinguishers in your
dyno room.
Industrial Noise Control, Inc.?Industrial Noise Control, Inc. offers a zinc-coated steel
room custom built to your specifications. This room meets all dyno room
requirements. The dyno room must be clean and dry with a comfortable room air
temperature above 32 degrees Fahrenheit (0 degrees Celsius), and have some system
of exhaust extraction. For more information on a dyno room, refer to your 
Pre-Installation Guide For Model 200i, 250i, 200iP, and 250iP Motorcycle
Dynamometers (P/N 98129103).

There are some advantages to connecting the DynoWare RT to a network, particularly
a wireless network. With DynoWare RT on a network, you don't have to have one
dedicated computer for the dyno. Any computer on the network can connect and
operate the dyno. A wireless connection allows you to control the dyno from inside the
vehicle without a cable running to the DynoWare RT main module.
Note: Only one computer at a time can connect.
When the DynoWare RT main module is on a network connected to the internet,
automatic updates for both the box and software are possible.
