Trade-in deal… for older DYNOmite Data Computers
This program was supposed to end in March of this year, but so many users asked to delay it until after their Spring rush, we relented. Here is your last opportunity to get serious at this discounted price!
Those still running either an earlier handheld DYNOmite-I or DYNOmite-II Data Acquisition Computer already know they are not supported by DYNO-MAX 2000. But, some have been holding off upgrading -because of a pre-season workload or cash-flow that didn't make spending $1,000 (for the required electronics upgrade) easy.
Well, until September 21, 2004, those old units earn a 100% trade-up credit. Imagine modernizing to a DYNO-MAX 2000 ready, 15-channel, data acquisition computer -for only $499.
(Users running a DYNOmite-II, can even utilize their existing wiring harness.)
If you have not already taken a look at what DYNO-MAX 2000 can do for your testing results (and bottom line), call for our free Multimedia Demo Tour CD. Or, review the DYNO-MAX Version Comparison Chart (in our web site's Support section) for a feature by feature evaluation. As previous upgraders keep suggesting that we make clearer: “You will wish you made this advancement a long time ago!”
To arrange your own trade-up, telephone: 1-866-DYNOMITe (or e-mail: sales@land-and-sea.com). We can even arrange for same day UPS turnaround -to eliminate downtime.
DYNO-MAX Version 9.34...
A new Fuel Injection Mapping Automated Test Wizard is part of the latest DYNO-MAX 2000 "Pro" update. DYNO-MAX 2000 Version 9.34 SP #0 allows generating a desired Air/Fuel Ratio table and Auto Test for an engine -in seconds! That test is executed from a special Fuel Mapping Console -which prompts the operator for their target throttle % -while the dyno's load control regulates RPM. Settling time, cooling periods, etc. are all handled by the wizard. Once the test completes, DYNO-MAX outputs a deviation map for quickly re-programming the engine's ECU (any brand).
DYNO-MAX “Pro's” Graph Set Up features a new drop-down list for controlling display of average or difference Graph Lines and Data Points Column's (between overlaid runs). Also, any grouping of multiple graph tabs may be designated for simultaneous batch printing.
A powerful Smart Search™ database searching tool is available. It makes finding any previously saved run easy -even when you have thousands of stored tests and years of folders to hunt through.
The DYNOmite Smoke Opacity Meter now integrates directly with DYNO-MAX 2000. Diesel exhaust emissions may be displayed as either a percentage or in Hartridge Smoke Units.
9.34 adds several other features, including: support for Pocket DYNO-MAX remote control (see next page), logarithmic formula functions, “Megawatts” as one more formula Power units type, AFR Source list, User Preferences held by each Environment (instead of globally), and a few other minor tweaks. This release is available in the DYNO-MAX Support area for free downloading (to 9.0 through 9.33 licensees under a current support plan).
New Pocket DYNO-MAX™
This amazing remote control software package integrates DYNO-MAX 2000 "Pro" with your wireless Pocket PC (running Microsoft's Windows Mobile 2003). It allows monitoring the engine, controlling the dynamometer, and printing test results -all from within the vehicle (or your customer showroom) -without cords, proprietary hardware, or even a line-of-sight to your main console!
Features include: User configurable digital and analog bar gauge assignments, support for DYNO-MAX 2000's "Smart Record", torque zeroing, last run playback, single-click printing, and more. If one of your DYNO-MAX 2000 alarms goes off, Pocket DYNO-MAX provides both an audio and video warning.
Touch screen buttons provide one finger control of testing. The Pocket PC's “Joy stick” is used to control the DYNOmite's Hold RPM -just like DYNO-MAX's arrow keys can.
Supports Wi-Fi and Bluetooth wireless standards -no proprietary radio or infrared devices to deal with. You can monitor and control any of your DYNO-MAX 2000 pre-programmed engine break-in cycles or endurance tests from anywhere you have an internet connection -even from a coffee shop halfway around the globe!
Question of the Month...?
“How do I derive the ‘Driveline Power loss’ values to enter (on the Run Information -Vehicle tab) for my homemade chassis dyno?”
These parasitic drag fields are used to return lost horsepower (and torque) -consumed by the dynamometer's shaft bearings, drive belts, etc. -back into the displayed test results. For example: the roller's windage and pillow block bearings rob energy that would normally be delivered to the pavement. It does not matter if you are doing inertial or steady state (absorption) testing, this is delivered Hp that never makes it into the data acquisition computer!
Fortunately, it is relatively easy to perform your own coast down test, utilizing DYNO-MAX itself, for determining a very close approximation of these non-linear power losses. You will also need a small vehicle and a floor jack.
1) Place the vehicle onto the dyno without using straps! Wheel chocks alone will suffice, as no significant torque will be applied during this test.
2) If the dyno has a load cell, it must be properly calibrated and zeroed before beginning. The correct inertia values (for the roll assembly and any other drive components) must also be entered.
3) A floor jack under the axle (or an overhead lift for a bike dyno) should be in place -to lift the tires off the rolls during coast down.
4) Prepare DYNO-MAX for a manual recording. But do not press the console's Record button – yet. Stay in Knob (no load) mode!
5) With the test area clear, gently accelerate the vehicle to bring the dynamometer up to normal test speed. Then signal the driver to lift off the throttle and disengage the vehicle's transmission.
6) With the rolls coasting, jack the tires just clear of the roller(s).
7) Press DYNO-MAX's Record button to capture the coast down.
8) Once the dyno falls below 30 MPH (this takes some time), press Pause and then save the recording.
9) Edit Graph Set Up and use Time Averaging 0.1 second to graph Engine Power (only). Uncheck the Y-axis's “Lock Low to Zero” box, as you are graphing negative (lost) power!
10) Modify the Driveline Power loss Hp and Exponent fields (on the Run Information -Vehicle tab) to flatten (zero out) the negative horsepower graph line. Experiment to get the flattest overall line!
Tip: Try an exponent of 2 as a good average for the various parasitic loss curves involved. Leave the ‘RPM’ field at 5252, as it is merely a scaling anchor for generating the exponential curve.
11) That's it, these two fields' values may now be entered into the next New Run as your default Driveline Power loss values.
Customer Spotlight
GTech Motorsport
Located in Kent, England, GTech Motorsport was started in the 1970’s by Will Gollop. Will’s motorsports career began in 1973 when he prepared a Mini for Autocross -and went on to become that year's South East Autocross Champion. He finished at the top of International Rallycross events with that Mini. But building an engineering business left little time for competition over the next several years, so it wasn’t until the 1980’s, with backing from Saab, that Will was able to return to competition.
Over the years Will has undertaken some considerable research and development on the Lotus 3.5 liter V8 race engines. This work continues today along with multiple other engine projects. These projects include designing an all-new, highly innovative Ford Focus with a Ford Zetec 2 liter turbo-charged engine.
To develop such high performance race engines, GTech uses their DYNOmite Pro 1600 Engine Dynamometer. It's equipped with the latest version of DYNO-MAX 2000 “Pro” software, full automated servo load control, electronic throttle control, and knock sensing equipment. This dynamometer and software combination helps them conduct accurate engine tests while simulating real world operating environments. As EMS calibration engineers (for Motec EFIs, etc.), they rely heavily on DYNO-MAX's advanced Automated Test programing features.
Numerous high profile Rallycross race teams look to GTech for their innovative engine design, research, and development. So, it’s no wonder that the DYNOmite Dynamometer System is such and integral part of their ongoing engineering process.

Formula SAE 2004
During this May's competition in Pontiac, MI -with over 130 teams participating -Land & Sea handled all the on-site dynoing. By the end of the weekend, over 250 runs had been recorded! You may see the results at: http://www.sae.org/students/fsae2004results.xls
Car after car, racer after racer they came, waiting patiently for one or more last minute tuning sessions on the DYNOmite. Students and professors took a particular interest in our DYNO-MAX 2000 "Pro" software. That's because it outputs detailed curves -ideal for remapping the engine's' digital management systems. Efficiency, efficiency, efficiency is what this event is all about.
Land & Sea was pleased to work with these ambitious racers and up-and-coming engineers. It was especially exciting to watch New Hampshire's own Dartmouth College... finishing a strong 8th this year. We can't wait to get back in 2005!
