Land
& Sea’s Data Acquisition
Electronics, Controls, Accessories, and even free (Do-It-Yourself) dyno
plans allow
you to build your own system or bring an older analog
engine or chassis dynamometer
back to life. Our state-of-the-art DYNOmite data collection and engine control
computer and software deliver a price/performance ratio formerly unheard of in
professional dynamometer test systems.
Build your own dyno or
give an existing unit a new lease on
life.

Typical
electronics kits include DYNOmite data-acquisition computer with from 3 to over 112 channels (with or without optional
LCD display and pushbutton handheld interface), full-bridge strain gauge
equipped electronic load cell torque transducer, AC power supply/recharger, data
wiring harness, engine temperature thermistor, and protective
carrying case.
Free
– Do-It-Yourself Plans are available (with the purchase of any of
our data-acquisition systems) for building your own low-cost
dyno frames, stands, test-cells, etc.. Additionally, we offer prebuilt
subassemblies along with most major hardware components, links to useful
Tech-Talk articles, and plenty of expert advice. Since Land & Sea actually
manufactures our dyno equipment on-site, we have the machinery, the personnel,
and the experience to help you with your own
custom manufacturing or rebuilding jobs. Please feel free to give us a
call for more information.
Our DYNOmite
data-acquisition computer automatically
capture true torque, RPM, elapsed time, etc., while calculating Hp at up to
1,000 readings per second (that’s per channel, not just a total). The board’s
ECU can even be set to automatically apply Standard SAE correction factors for air
temperature, barometric pressure, and relative humidity. This eliminates running
engines to death while trying to manually record all the data. Handheld
DYNOmite models display results on their LCDs and can
print to an optional portable battery-powered printer. No prior computer
knowledge is required to start testing and analyzing data like the pros.
DYNO-MAX™ Software
- the heart of your dynamometer investment. Since the software is the
dynamometer's most important component, be sure to choose wisely! DYNO-MAX
creates a full engine dynamometer lab console on your PC.
Features include: real-time trace-chart graph display, adjustable visual and
voice limit warnings, pushbutton controls, user configurable analog and digital
gauges, plus incredibly powerful post-test data analysis tools. (Click
here
for a full list of features.)
Integrate your own
Windows PC
by using DYNO-MAX with appropriate automated electronic load and
throttle control hardware options for keyboard dyno control. Without special
programming, operators can easily execute even complex race simulations and
engine test cycles. No other dyno software adapts and expands so easily to virtually any level
of testing sophistication.
Affordable
expansion upgrades (up to 112+ channels)
include: fuel flow and airflow turbines, brake
specific fuel
consumption, brake
specific air consumption, air/fuel
ratio, exhaust
gas temperature, engine
temperature thermistors, air
temperature, humidity,
barometric pressure, sparkplug thermocouple kits,
RTDs, pressure transducers, 0-5 volt auxiliary inputs (for
many wide band air/fuel ratio sensors, knock sensors, etc.) and outputs, high-speed
cylinder pressure mapping, and both servo load and throttle control options.
Like the DYNOmite itself, these upgrades won’t eat your entire testing budget.
Available
torque sensor options include full-bridge
(temperature-compensated) strain gauge S-beam load cells, high resolution
pressure transducers, and wireless rotary-torque transducers. All
of them are
maintenance free and feature our semi-automatic pushbutton zero offset calibration.
Conversions can usually retain the system’s original torque sensor and display
in parallel with the new electronics.
Forget inaccurate paper and pencil
logging, throw out that DOS-based software and
get professional one-person operation. Owners of older analog Clayton,
DataMite, Dynojet,
Froude, Go Power, K & O, Maha, Maxwell, Mustang,
Performance Trends, Sport-Dyno, Stuska,
Sun Road-a-Matic, SuperFlow, TAT,
etc. brakes, software, or rollers can
now take advantage of most DYNOmite and DYNO-MAX features without purchasing new
absorbers or engine stands.
Advanced standard features
including: “Smart Record™,” real-time data dampening, spike filtering,
playback data averaging, atmospheric correction, auto-zeroing, instant
playback, and integral rev-limiter.
 DYNO-MAX control functions
include: water brake, hydraulic, AC, or eddy current absorber
load control, throttle position torque control, and switched relays to control
fuel pump(s), engine starter, cell ventilation blower, water supply
valves, N2O injection, etc. Choose from “canned” cycles, or customize
tests using its advanced custom automated test editor tool.
Electronic load and throttle control
options – just push buttons to select the test
RPM, or set a sweep rate and the DYNOmite’s own advanced PID algorithm runs the whole
show – all hands free.
Inexpensively
update that obsolete analog dyno for the new
millennium. Computerization eliminates the need for two people to “try” and
monitor the operation of your engine testing. It also eliminates observer bias
from the results. Today’s front-runners are already scrutinizing every single
line of their own dynamometer’s data; do not be left behind!
Convert motor, transmission, or chassis
dynamometers! The DYNOmite and DYNO-MAX team includes features to
allow optimizing them for almost any type or power train testing. Whether you
are restoring some old analog emissions rolling-road, building a new
transmission dyno, measuring an electric or air-motor’s performance, upgrading a
speedometer calibration tester, or secretly testing your own space-age
transportation invention… we are ready to help you. A DYNOmite conversion can
bring full load control and road-load simulations to your inertia dyno, or
cylinder pressure mapping to many 1960 vintage water-brake systems. It does not
matter if you are monitoring 100 or 128,000+ RPM shaft speeds. We offer ¼ to
10,000 ft-lb load cells, and support multi-channel data collection rates from
200 to over 200,000 Hertz. If you are upgrading a dyno, you have found your
solution.
Doubles
as a race recorder to capture all your standard
dyno data - at the track. Our array of “on-vehicle” sensor options include: forward
and lateral Gs, distance, MPH, MPG, shift ratio, transmission slip, ETs, 0-5
volt auxiliary inputs (for lambda sensors, shock/suspension travel, etc.), wireless
rotating driveshaft torque and Hp, OBD-II data, and GPS location (maps the
vehicle’s position via orbiting satellites). Radio modem telemetry is
even available
to broadcast track data back to your race pit crew’s laptop.
Live-person technical phone support
provides a significant advantage over other companies’ obnoxious
“voice mail” runarounds. Our standard hardware phone and e-mail support, plus
access to the special DYNOmite owners 24/7 web support area, are all FREE!
