Land & Sea expands DYNOmite
manufacturing capacity (again)
It is already getting crowded here inside our four-year-old Concord,
NH manufacturing plant. We are currently installing another new
(and massive) press brake in our dynamometer fab-line area. This
custom-built bender features a high-speed ram running off its
state-of-the-art synchronized (11 axis) 3D CNC control – and
includes direct-from-CAM (solid modeling) software integration.
In order to handle even our larger (industrial) dynamometer-frame
jobs (e.g. ½“ diamond-plate steel), the twenty-foot-long brake can
provide nearly a million pounds of bending force. Its four
CNC-controlled lifting tables, independent ram cylinders, and
six-axis back gauges allow automatically forming our DYNOmite
frames signature large-radius (strong) tapered bends.
Besides checking out the pre-installation testing picture (above),
you may eventually see it in action, as part of our website’s online
“DYNOmite Factory Tour Video.” That movie may be viewed at:
www.land-and-sea.com/corporate/factory-tour_video.htm
Also due to arrive soon, and eat up yet more floor space, is a new
Broomfield heavy-duty CNC-controlled coil-winding system
(lower left image). This purpose-built machine, is integral to the
ongoing expansion of our eddy-current absorber line. It will be
handling precision winding of those units’ magnetic coils – with
some running over three feet in diameter! Such huge coils are the
required heart of our larger liquid-cooled eddy-current absorbers.
Importantly, its coil mandrels and wire-tensioning system (not
shown in image) are engineered to reliably deal with wrapping
lower-resistance, yet trickier to wind, square wire. This rugged
machine is slated to arrive here sometime in mid-April.
Note: We utilize square wire because it provides about 25% more
cross-sectional area, for any given diameter, than (less expensive)
round wire. That allows us to attain a higher ampere * turns value
– which translates into a stronger magnetic field for more torque!
This higher-current capacity wire is an integral feature in both our
liquid-cooled and our air-cooled “Ultra-Torque” eddy-current
absorber coils.

Question of the month...?
“Can I change the order of the columns on my run’s Data-Points
listings? I want the Hp to be on the left of my Torque column.”
Sure, this is very simple to do – in DYNO-MAX 2010, as well as in
the older DYNO-MAX 2000 version. Here are the steps to follow:
1) As with many customization settings in DYNO-MAX, you first
decide if you want this customization to apply to just this run, or all
future tests. If it is a one-time thing, then perform your subsequent
graph-setup steps after you save this one run’s data. Conversely, to
apply your new column format for the foreseeable future, perform
the graph setup changes on a “New Run” (before recording data).
2) Open the graph-setup editor, and click on the first graph tab that
you wish to alter the data-points listing column order for.
3) Highlight (click on) the formula line you wish to move left on
the column listing, and click the “Up” button (as shown in the
example images below).
4) Now examine your results (in the second pair of images below).
Notice that the selected Hp formula line has moved on up in the list
box. It will now appear to the left of the Torque formula column in
the data-points listing. In other words, the formula-row order (in the
graph-setup editor) corresponds with the the column order for the
data-points listing.
5) Repeat these steps to move columns into any order. Each graph
tab is individually configurable, different orders may apply to each.
Note: The far-left RPM (X-axis) column cannot be moved right.

ZIP YOUR TEST RUN FILES FOR
E-MAILING TO CUSTOMERS OR SUPPORT…
DYNO-MAX 2000 first introduced features to
make it easy for you to bundle up recorded
runs for easy e-mailing, to your customers or
support, using most MAPI-compliant e-mail
packages (Messaging Application Programming
Interface). You may have already used the
“File - Send To - E-Mail Current Run to Land &
Sea…” menu choice to automatically create a
pre-addressed e-mail, with attachments, for
“support@land-and-sea.com...” – ready to hit
send. This was the quickest way to e-mail all
an open test’s run information (.run) file, data
(.raw) files, etc.
However, today many people use non-MAPI
internet-based e-mail programs – like Gmail or
Hotmail. For them, the above method is out.
Fortunately, if you run DYNO-MAX 2010, this
need not be an issue. Simply click on the “File
- Send To - Zip Current Run for E-Mailing to
Owner” choice. It automatically creates an
appropriately named, zipped file on your
Desktop, ready for attaching to any e-mail.
Note: You may even set an alternate ‘copy
location’ from the “Tools - Preferences -
General” tab.
The above “Owner” menu choice will include
just the files your customer would need to
review their runs (e.g. using the free Demo
download of DYNO-MAX 2010). Naturally, there
is also a “File - Send To - Zip Current Run for
E-Mailing to Support” option. It works the
same way, but bundles in all the relevant
setting and log files that help our support
technicians and engineers to answer your
DYNO-MAX related questions.
We actively encourage DYNO-MAX 2010 users,
who are under a current Priority Support Plan,
to take advantage of the program’s built-in
zipping and/or e-mail technical-support
features. If your PC or laptop has e-mail
capability, help is only a couple of mouse
clicks away.

DYNOmite EEPROM Version
9.973 is now available
Operators running our DYNOmite-Pro (or Lite) may update to
EEPROM version 9.973 – as always, this is a free upgrade. This
verison adds the following two enhancements:
There is now support for a new “Minimum Hold RPM-C” loadcontrol
parameter. This new parameter specifies an absorber
RPM that must be exceeded before the DYNOmite auto-load
control will apply any power absorption. The resulting delay
helps avoid excessive “off the line” stalling or loading, during
hard chassis-dynamometer launching – from near zero MPH.
Such overloading is typically only an issue when utilizing an
absorber capable of delivering significant low-speed resistance
(e.g. large AC-motor or hydraulic-gear absorbers).
This setting is end-user accessible from the DYNO-MAX “Pro”
“Electronics - Configure DYNOmite Controls” screen, of the
new DYNO-MAX 2010 versions – 10.17 (or later). Be aware, it
is only applicable in “RPM Source #3 (RPM-A, RPM-C)” mode
– and while operating at a relatively low shift ratio. “Out of the
box,” this new setting initially defaults to 0 RPM.
Adds RPM-C “Smart Latency” synchronization, for improving
the inertial-compensation accuracy and the inertial-torque data
smoothness – meaning less spiky. Providing accurate inertial
compensation, for the flywheel-energy involved in spinning up
(engine, absorber and/or chassis roller) masses, requires precise
acceleration measurements. It also demands that this interruptderived
(RPM-encoder based) acceleration data be kept in phase
(time) with the sampled (strain-gauge based) torque data. This is
easier said than done, since the encoder refresh rate increases
with RPM, while the torque data has a fixed time lag (based on
circuit capacitance). Smart Latency utilizes sliding frames, with
micro-second interpolation, to minimize RPM/time/torque shift –
resulting in more accurate data out.
The new EEPROM, with Smart Latency, does not require adding
higher-count encoders to see the benefits of the new algorithms.
In fact, even systems running just a single pulse-per-revolution
RPM source (1 PPR) will often attain acceleration RPM data
smoothness and “inertial versus measured” torque
synchronization that surpasses systems running encoders with
counts of 60, 100, or even 1,024 lines.
To get the EEPROM upgrade, obtain the required flash update file
– either from an e-mail (from Support) or via our online downloads
(as described below):
DYNO-MAX operators who have their dynamometer’s PC online,
may select “Electronics - Display DYNOmite Parameters...” and
then click the “Check for Updates...” button. Or, using any PC with
Internet access, you may visit our web site’s DYNOmite Support
Documents section to download the update file. Before flashing, be
sure to review the “Electronics - Flash DYNOmite Firmware” help
topic in DYNO-MAX.
Customer Spotlight
Gifford Brothers Racing
Howard Gifford, of Ottawa Ontario Canada, has been
in the top level of oval track snowmobile racing since 1975. In
2007 he won the Eastern Pro Tour Champ 440 season-points
championship. After winning that, Howard retired from driving,
and today, Gifford Brothers Racing specializes in designing and
building hydroformed pipes – for most of the top race teams.
Howard says “the exhaust on a two stroke is where 75% of the
power comes from. A two-stroke pipe is a supercharger – without
moving parts. It uses sonic waves to extract a fresh charge into
the pipe, stuffing it back into the cylinder (trapped) at the precise
moment the exhaust-port closes. Without a dyno, development of
race pipes is almost impossible. Until recently, I relied on someone
else’s dyno, but that limited my ability to perfect my designs.
“By hydroforming, I can build a perfectly ripple-free and seamless
curved pipe – within 1mm of the design spec. This is why my
pipes have won more races than any other pipe builder in the
Eastern Pro circuit.
“My test cell started out as a 30’ x 30’ garage. I had to take into
consideration that I live in a residential area – soundproofing was
a must. I built a 16’ x 20’ addition as my test-cell room. The walls
are built with double-offset studs with both the pink and the green
insulation – along with two layers of drywall. The ceiling has 24"
thick blown-in insulation. I left the existing garage door in place,
to create two rooms – and act as a second sound barrier. The cell
has double insulated doors, so I can even roll in a sled – to test in
the chassis. Two 16" ducts in the ceiling and blowers circulate air
through the gable-end wall. The exhaust is extracted through a
double-muffled vacuum unit, that exits into a 5" truck muffler.
Outside, the sound is barely audible.
“The dyno itself now has the ability to do manual hold-RPM runs
and automated-test pulls. At the push of a button it measures
RPM, torque, power, BSFC, EGT, fuel flow, airflow, air-to-fuel
ratio, water-in and water-out temp, and dyno-coolant temperature.
It corrects all this with an automatic weather station that corrects
to standard, SAE, JIS, or observed readings.”

Introducing the new modular
DYNOmite Pro+ Console
Many professional dynamometer operators require more screenmonitoring
and working area than a standard DYNOmite Pro
Console provides. That problem is solved by the latest addition to
our modular dynamometer line – the Pro + (plus) model console.
This system’s modular design allows end users to create just the
personalized console configuration that fits their testing needs and
control-room layout. In the accompanying image (above right), a
popular wrap-around design is shown. This layout is built using an
extrawide dual-monitor “master” console with a pair of 45-degree
“wings” and two wide-screen monitor “companion” consoles.
While what to display on the monitors is ultimately up to the
operator, this is what is on the above system (from left to right):
Third-party fuel-mapping program
Digital dyno coolant tank temperatures (with alarm relay)
Redundant (from PC) DYNOmite analog engine gauges
DYNO-MAX 2010 “Pro” across dual monitors
Digital dyno coolant pump pressure (with alarm relay)
Kindle Fire with operator test program
Control room video monitor
Wireless remote-control tablet with DYNO-MAX
The system shown could just have easily been built with only a left
or right wing, or as one very long array of standard, wide-screen,
and/or dual-screen stations. If your dyno-cell layout requires it, the
modular units can even be configured in a 270-degree semi-circle
ring. Note: The wings may be ordered with custom combinations of
digital gauges, relay controls, audio speakers, AFR readouts, and
wireless accessories.
