Disclaimers
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.
Do not connect or disconnect cables or components on the dynamometer with the power on.
Always wear protective clothing, ear protection, and eye protection (goggles, safety glasses) when
using and servicing the dynamometer.
Equipment Power Requirements
The dynamometer has specific power requirements. Connecting the dynamometer to the incorrect
voltage will void the dynamometer warranty. Installation may require a licensed electrician.
Potentially Lethal Voltages
Components attached to and within the dynamometer operate with potentially lethal voltages. To
provide the greatest assurance of safety, the AC power cord(s) must be disconnected from the power
source before servicing electrical components or wiring. Disconnect all power cords before servicing
electrical components for the greatest assurance of safety.

WARN IN GS
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
dyn amo me ter s t o be ver y t ole ran t o f st ati c sh oc ks by the users, but the electronics are vulnerable when
the electronics are exposed. ESD occurs as a result of a difference of potential between two objects
when the two objects 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
are handled. Touch the chassis of the dynamometer before touching any of the electronics. By touching
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 handling 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. Keep battery vent caps in position. Prohibit smoking and avoid creation of flames and sparks
nearby.
Wear protective clothing, eye and face protection, when charging or handling batteries.

Other Potential Hazards
The AC power outlet shall be installed near the equipment and it shall be easily accessible to allow for
disconnect before service.
The dynamometer should be located in a well ventilated area. There is a carbon monoxide hazard with
all internal combustion engines. Engine exhaust contains poisonous carbon monoxide gas. Breathing
it could cause death.
Any dyno room design must incorporate sufficient exhaust extraction.
Always wear proper ear and eye protection when operating the dynamometer.
Never operate the dynamometer with the covers removed.
Never stand behind the dynamometer when in operation.
Never operate the dynamometer when there is excessive vibration or noise. Resolve these problems
before proceeding.
Never fuel the vehicle on the dynamometer unless appropriate safety measures are taken.
Verify brake operation before beginning any dynamometer testing.
Verify the vehicle is properly secured 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.

CHAPTER 1
Introduction
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 vehicle’s engine while supplying fresh
oxygen for you and your vehicle to breathe. It is a common misconception that you
cannot tune a vehicle 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.
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.

This section will walk you through removing the dyno from the crate and installing
the dyno in front of your lift.
REMOVING THE DYNO FROM THE CRATE
You will need to provide equipment capable of lifting a minimum of 2,722 kg.
(6,000 lb.) to move the crated dyno into position in your dyno room. You will also
need a pair of straps capable of supporting the same weight. Dynojet recommends
using two 2-inch x 6-foot single loop style straps. Refer to “Forklift Requirements” on
page 1-7.
RECORD
Be sure you record the dynamometer number on the inside cover of this
manual.
1 Remove the crate braces that support the top portion of the crate.
2 Remove the four lag bolts and washers securing the dyno to the crate base using a
9/16-inch socket, open or box end wrench.
3 Route the loop strap through the opening in the dyno frame and through itself.
Pull the strap tight. Do this on each side of the dyno frame.
4 Push the forklift forks together.
5 Place each loop strap over both forks.
Note: The straps must be the same length and meet in the middle. Verify each
loop strap is over both forks to prevent the forks from being pulled apart.
6 Using the forklift, carefully lift the dyno off the crate and move it into position in
your dyno room.

Connecting the RPM Pickup
CONNECTING THE RPM PICKUP
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
Your Dynojet dynamometer includes a primary wire inductive pickup and two
secondary wire inductive pickups. These small “clothespin like” inductive pickups are
used to sense RPM. An RPM pickup is required if you want to view torque graphs.
Generally you will use one secondary wire inductive pickup on a spark plug wire.
Vehicles with wasted spark ignition systems may require two secondary inductive
pickups. On a wasted spark ignition, typically one coil will be connected to two spark
plug wires. Attach one secondary pickup to each of these wires. If the pickups are
connected to two plug wires that do not fire at the same time, an erratic RPM readout
may occur. The primary wire inductive pickup senses RPM pulses from the coil.
Although this pickup location generally works better, it is harder to find the correct
location to connect the RPM pickup.
Note: If a pickup is not being used, disconnect it from the dyno electronics to
prevent any stray pick up of signals.
The optional Optical Sensor is useful on diesel powered vehicles, MSD ignitions, and
other high RFI ignition systems. For more detailed information on the Optical Sensor,
refer to the Optical RPM Sensor Installation Guide (P/N 98295109).

Inductive pickups are very fragile. The ferrite core can easily be damaged and
is not covered under warranty. Dropping, snapping, vibration, and heat can all
damage the ferrite core.
The dyno electronics RPM module contains the electronics that sense the RPM pulses.
An auto-gain circuit looks at only the peak voltage of the vehicle’s spark, ignoring the
lower voltages to help reduce electronic noise problems. Wasted spark ignition
systems will produce a lower voltage level on the exhaust stroke than the
compression stroke. By definition of the auto-gain circuit, lower voltage spark levels
will be ignored, missing every other spark the vehicle would produce.

CONNECTING THE SECONDARY INDUCTIVE PICKUP
The secondary inductive pickup cannot be in contact with, or it’s connecting wire be
crossing, other engine electrical wires or stray electrical interference may result.
1 Clip the secondary inductive pickup around one spark plug wire.
2 Route the inductive pickup cable to the RPM Module making sure the cable is
clear of devices that produce electronic noise (spark plug wires, coil wire,
coil etc.).
Note: Inductive pickup placement is important. Position the inductive pickup so
that it is not making contact with any other spark plug wires. Separate the spark
plug wire from the spark plug wire bundle for proper operation.
Note: You must ground the vehicle to the dyno for the electronics to function
properly.

BASIC DYNO OPERATION
PRE-RUN INSPECTION
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
Perform a vehicle inspection before making a run.
• Check the radiator coolant and oil levels.
•Check the fuel source.
• Rotate the drum(s) and check for rocks caught in the tire tread that could fly out.
• Check the tire pressure and tire speed rating. Improperly inflated tires or
exceeding the maximum speed rating can result in premature wear or severe tire
damage. Make sure the tire has no major deficiencies (cracks in sidewalls,
tread life, etc.).
• Visually inspect the vehicle. Make sure it is in safe running order.
• Make sure ear protection and safety glasses are used when the dyno is being
operated.
• Check the tie-down straps to make sure that they are tight and secured.
• Check the drive tires to be sure that they are aligned correctly on the
dynamometer’s drums.
Pre-Run Inspection
• Keep all rotating components clear at all times.
• Only the operator should be near the dyno or the vehicle during the test.
• Never allow any person(s) to stand behind the dyno or vehicle when it is being
operated.
• Perform any other safety inspections appropriate to running your vehicle on the
dyno.
Never allow any person(s) to stand behind the dyno or vehicle when it is being
operated. Only the operator should be near the dyno or the vehicle during the
test.
BEFORE STARTING THE ENGINE
Connect an exhaust hose or hoses (if dual exhaust) on the vehicle, make sure the
hose fits over the tail pipe, is not plugged or kinked and the hose is vented correctly
out of the dyno room.
Engine exhaust contains poisonous carbon monoxide gas. Breathing it could
cause death. Operate machine in well ventilated area.

CHAPTER 3
Pre-Run Inspection
ENGINE WARM UP
Warm the vehicle’s engine and drivetrain before beginning testing. Consistent engine
temperatures will assure your runs are repeatable.
AFTER ENGINE WARM UP
Always leave the vehicle in park (automatic transmission) or in first gear (manual
transmission), with the engine off, and make sure the emergency brake and the dyno
brake are on when you get out of the vehicle.
• Fix any fuel, oil, or coolant leaks that may have shown up after engine warm up and
check the carburetor for leaks.
• Any loud or unusual engine noises or excessive exhaust smoke should be resolved
before continuing.

MAKING A TEST RUN
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
Dyno runs provide safe, reliable road testing right in the shop. The dyno allows you to
measure, record, and diagnose performance problems quickly. The dyno combined
with WinPEP 7 produces consistent, easily interpretable power graphs. Use the
following instructions to ensure repeatable and accurate measurements.
1 Verify the vehicle is secured properly.
2 Place the vehicle in a low gear and release the dyno brake using the hand held
pendant.
3 Slowly accelerate the vehicle to 20 m.p.h.
4 Test the tachometer operation.
4a Rev the engine. The gauges on the computer screen should be moving. If
the tachometer is moving but not registering the correct RPM values, the
number of degrees of revolution of the crank shaft (the plug fires number) is
incorrect.
4b Stop the vehicle, return to the MakeRun Configuration dialog box, and enter
the correct value for the plug firing order.
5 Press the red brake button to apply 100% braking and slow down the vehicle.
Making a Test Run
Using the vehicle’s own brakes to slow or stop the drum at speeds over 30
m.p.h. can severely over heat the brake parts. Dynojet dynamometers with the
air brake or eddy current brake accessory can be used to slow the vehicle and
drum to a full stop at any speed. The vehicle’s brakes should be used in an
emergency stop situation only.
6 Shut the engine off and put the vehicle in gear (manual transmission) or park
(automatic transmission).
7 Set the vehicle’s parking brake and leave the dyno brake on.
8 Perform a final inspection.
• Verify the drive tire’s alignment on the dyno drums.
• Make any adjustments to the tie-down straps as needed.
• Perform any other safety checks that you deem appropriate to your particular
situation.
You are now ready to make a high speed run on the dyno. Refer to your WinPep 7
User Guide for more detailed instructions.

PREVENTATIVE MAINTENANCE
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
This section covers maintenance items for all model 224 dynos with the Spring
Applied Air Release (SAAR) brake. For more detailed maintenance instructions, refer
to the Maintenance Guide for Automotive Dynamometers (P/N 98119101).
THINGS TO CHECK
• Check all air fittings for leaks monthly. Correct any leaks found.
• Once per month verify the brake pressure gauge reads 100psi (690kPa). Adjust the
regulator if the pressure is out of specification. Refer to page 3-13 for more
information.
• Check the brake shoe clearance. Refer to page 3-14 for more information.
•Dyno Bearing Grease:
Under steady use, over 25 runs per day, each bearing should receive .65oz (19 ml)
of a recommended grease every 2 months.
Under occasional use, less than 25 runs per day, each bearing should receive
.65oz (19 ml) of a recommended grease every six months.

Preventative Maintenance
MAINTAINING THE SAAR BRAKE SHOE CLEARANCE
1 Verify the area is clear and the dyno can be operated safely.
2 Power up the dyno electronics.
3 Using the pendant, turn the brake to the OFF position. This will release the SAAR
brake by moving the brake shoe away from the drum.
Keep hands and fingers clear when operating dyno.
4 Measure the gap between the brake shoe and the drum surface. This gap should
be between .125 inch - .375 inch (3mm - 10mm).
Note: For clarity, the dyno frame is shown transparently to reveal the drum.
Note: The mounting bracket shown is used with the SAAR upgrade. Factory
installed SAAR brakes use a slightly different bracket.
