Dyno DataMite v3.2 for Windows 95/98/Me/XP/2000/NT

Data Logger and Computer Software to Measure, Graph, Report and Analyze Dynamometer Data from Inertia (flywheel) Dynos or Absorber (torque arm) Dynos

Overview:

Our affordable 20 channel DataMite III USB or smaller DataMite Mini USB can computerize your dynamometer for improved accuracy and time savings. You can watch "real time" gauges as you run the engine, make color torque and HP graphs and print them in color with a color printer, overlay 2 or more graphs for comparisons, save nearly an unlimited number of runs for retrieval in the future, make reports and averages over most any RPM range and much more.

We've instrumented over 400 dynos, from small RC engines using 7" diameter inertia wheels, to inertia dynos running 2500 HP blown alcohol motors. We've retrofitted Clayton (tm) chassis dynamometers, Go Power (tm) and Stuska (tm) engine dynos, and hundreds of other custom, home built and DIY dynos. If you've got a dyno of any type, we can add instrumentation to give you accurate and professional results. Click here for some pictures of our customer's dynos.

Performance Trends has been doing racing software since 1986, so we know what engine builders need and how to make it easy. You’ll be amazed to find all the powerful, yet "easy-to-use" features in our software, and surprised that we can still keep our costs so low. From a simple system recording just RPM/torque/HP up to a complete system recording fuel pressure, fuel flow, oil pressure, A/F ratio, 8 exhaust temperatures, weather conditions and more; Performance Trends can supply the complete package.

You can tune your engines by measuring additional inputs, like fuel flow, air flow, oil or fuel pressure and A/F. Setting A/F (air to fuel ratio or how rich the engine is running) is critical to obtaining peak performance. A/F can now be inexpensively added to most any dyno, even small Kart dynos, because of the tremendous advances with wide band oxygen sensors. See picture below.

Our reliable packages and customer service give you confidence you will be testing very soon after getting your system from us. We offer free phone support, and have several Troubleshooting features built in the software. Click here to meet one of our customers who has over 15,000 dyno pulls on his DataMite system, and it's still running problem free.

Current Readings Screen for 30 Channel DataMite II

The screen above shows the use of "Color Warnings", where you can choose certain limits for certain channels. When an output goes either above or below a certain value (your choice), you can request a Caution (in yellow) or Warning (in red) color to be displayed to highlight this condition. Color warnings and other options are available by clicking on Options at the top of the Current Readings screen.

Features:

The software comes in either Basic or Pro versions, and has several features, including:

Basic Version:

	Capability to configure and calibrate the software for most any combination of sensors you have installed on the DataMite data logger.
	Capability to tailor the program to work with most any type of dynamometer, including inertia wheel types, absorber types (with load cells and lever arms), and even chassis dynamometers.
	User friendly, Windows interface, compatible with Windows 98, Me, NT, 2000 and XP.
	Can print results using most any Windows compatible printer, many times in color.
	Save nearly unlimited number of tests for recall, comparison and analysis in the future.
	Allows several reporting and graphing options for analysis, either vs RPM or vs time in seconds.
	Real time display of selected channels.
	Built in calibrations for most sensors, like thermocouples, pressure sensors, A/F sensors, etc, make it easy to get up and running, or add sensors.

Added Features for Pro Version:

	You can also input and/or record: Additional dyno details like frictional losses in the dyno system (which affect the torque and HP recorded), correct for engine inertia effects when running an accelerating test (which is all inertia dyno tests), dimensions and weights of more inertia dyno components, etc. Engine specs like bore, stroke, head descriptions, cam descriptions, etc. Additional test conditions like fuel, coolant/head temp, etc.
	Customize printed reports and especially graphs. You can include comments for each engine graphed.
	Write ASCII files for importing data into other computer programs.
	Filter (find) past tests based on certain criteria, like Peak HP, certain Customer name, etc.
	Overlay graphs for more than 2 tests (up to 6 tests).
	Time align graphs (shift one graph left or right over another graph) vs time for better comparisons.
	"History Log", keeps a running log of tests you have recently started new, run, graphed or reported.
	"Analyze" button for graphs, let you use to cursor lines to "analyze" (average, max and min) what’s between the 2 cursors.
	For absorber, water brake dynos, the Pro version lets you do accelerating tests, decelerating tests, and use switches to mark the beginning and end of the run.
	For chassis dynos, you can load, save and recall (open) sets of specs which describe a vehicle's tire size and gear ratio for more automatic measurement of clutch slippage, or calculating engine RPM from dyno roller RPM if you choose not to record engine RPM directly.
	You can display a "calculated" Engine RPM on the live display of Current Readings (calculated from Dyno RPM and gear ratio) when you do not have a reliable engine RPM signal.
	On special request, you can correct for Engine Inertia effects for absorber, water brake dynos.
	You can choose to display calculated outputs, like HP, MPH, KPH, BSFC, etc. on the live display.
	Save certain "Formats" of graphs and reports, for easy construction of these graphs and report types in the future.
	Allows for chassis dyno results to be graphed or reported vs MPH or KPH.
	Allows for Comparison Reports, to display tabular data of 2 or more runs, side by side, with the difference also calculated and displayed.
	Allows for "fine tuning" of certain calibrations of standard sensors (like thermocouples) by adding a "Correction" to the calibration.
	And much more.

Retrofitting Your Dyno:

The Dyno DataMite system has been used to computerize Stuska (tm), Go Power, Davenport, Prototype, Clayton, and numerous other brands of dynos. In some cases we can use some of your existing sensors. Call or email your details about your dyno, including:

Engine Only or Chassis Dyno

Torque measurement method your dyno is using:

	Inertia
	Torque measured with a pressure gauge or sensor
	Torque measured with a load cell
	Some other method (please describe)
