Follow this procedure closely.

Do not connect the hardware before software program has been fully installed on computer.

1. Insert CD and install mjp_1100_xxx.exe. (If installing does not start automatically, locate the CD/DVD drive in My computer or Total Commander (or other file

handling program) and click mjp_1100.exe.) The program installs automatically in c:\program files\MJPower Engineering. An icon will be installed on the desktop.

2. Click "start" / programs / MJPower Engineering / usb-driver / install. The driver will install itself in the right place.

3. Open program from desktop shortcut and enter password from CD

4. This screen will show:

Click the SETUP tab. Here you can customize the dyno software to your needs. Setup should be seen as a configuration

page for choosing preferences on a general basis. For configuring individual tests with out changing general prefeerences, make changes in

"Parameters", "test" or other tabs.

1. Eg. Your Company Name and Phone number.

2. Startup coordinates for graph window Enter values that will match the range in which you expect to perform tests.

You can always change the values or customize the looks of graphs and power curves during everyday testing in the Parameters tab.

3. Weatherstation adjustment constants.

Constants is explained in a separate document - weatherstation - where you will also find directions for the

mandatory semi-yearly weatherstation adjustment procedure.

4.

Select if Speed will be displayed as Kph / Mph , Power as Hp / Kw. If You will use Fahrenheit / Celsius , Millibar / Inch Hg.

Checking the Print Owner Name will Print your Company Name on printouts. Checking the Print with header button will print the mjpprint.bmp on the top of printouts.

5. Graph linewidth for printing The higher number chosen, the wider the printed graph lines.

6. Dyno model Select your Dyno type

7. Roller type Only if you run the software on the 2100/2200 Dyno’s.

8. port status will show a green light if port is open, which it must be. Red if closed. The Usb Box Firmware number is Displayed here if connection between Computer and Box is Ok.

Make sure that the Firmware number is matching the requirements shown on the Dyno programs top if you upgrade the

Software.

9. Roller weight: 184 on 1100 Dyno’s and 210 on Kart Dyno’s

10. Update loaded tests with roller weight: leave unchecked in normal use, if checked it will use the Roller Weight values in the Roller Weight Window on older tests you load from the Harddisk.

11. Initial test folder should be set to your preferred Test file folder ( initially set to C:\ )

12. Save Setup File You now have completed the setup. Click the button to save the changes. A promt will

confirm saved correctly. Remember to press

save button each time you change any values on the Setup page.

13. Usb return Codes Shows Ok when Usb data is transferred correct

Timeout if transmission is delayed Error if transfer is faulty.

Click the Param. tab and this screen will show:

Correction factor functions: 1 -4: When a test session is finished, the weather data is automatically saved with the session, so under normal

circumstances there will be no need to use these functions. It is still possible to manually enter the values for humidity, barometric pressure and temperature if need should be.

The weatherstation can be polled by clicking the "Get data from weatherstation " button.

If values are changed, click the "Use correction factor " and the new correction numbers are now used in the active test (Test 1).

By clicking Factor = 1.00 (uncorrected hp) button, test session 1 graphs will be displayed as uncorrected power.

If the typed-in numbers exceed the limits of the correction table, an error message will be displayed announcing that

the correction figure is changed to 1.000.

Correction factor type. Selects which type of Correction standard used, see separate Document.

5. Graph scheme coordinates: Specific graph window coordinates can be typed manually here. It is possible to enter a negative value in the Start Hp window, this way you can observe the engine braking force

during deceleration.

6. Calculator button displays a simple calculator.

7. Set air- and roller resistance. A special feature is the ability to display a combined air and rolling resistance curve together with roller torque graph (torque related to speed).

Use this to predict the theoretic topspeed of the vehicle by viewing the crossover point where the yellow wind resistance curve crosses the torque graph in top gear.

The air resistance examples drop down box holds some values for different types of bikes.

You have now configured the software to meet your needs and can now safely connect the control box (hardware) to the dyno and computer.

Important ! To avoid electrical problems causing erronous data sampling, the USB control box must be ground-

connected from the pin on the rear.

Graphs.Graphs.Graphs.Graphs.

On this screen are all the options necessary to display the graphs. You can watch 1 to 4 run graphs at the same time.

The select buttons are arranged in four groups (red-blue-green-purple), each group relating to a separate test session. Graph colour is identical to the button colour.

Inside each group the buttons are used to select which of the up to 3 runs in the test sequence you want to display.

TIP: Normally run 1 is used only as a "clean-out-the-engine" function. To diagnose the engine output, use run 2 and/or higher. Beneath the four groups are the checkboxes that determine how to show the graphs: as Horsepower, Torque or both.

Also you find the boxes to copy the number 1 test session (red) to any of the other test session boxes (this will make room for a new test session to be viewed as "Test 1" and can then be compared to the earlier runs. This way you can always see the latest four test sessions.

Fixed Gearing is checked if you have tested a std. gearbox equipped Vehicule and prefer the Rpm to be displayed on the Horizontal axes.

"Clear" : Check to deselect showing graphs from that box.

On the left side is the Speed / Speed - Rpm checkbox, to choose between the graphs showing speed only, or to include engine Rpm. Obviously, to display a Rpm graph, you need to register Rpm data during the test run. There is a series of buttons to step up/down the speed/rpm/power ranges. If you want to view a specific range you can either use the Zoom feature (see below), or set a specific value on the “Parameters” page. When selections are made, view the graphs by pressing the Refresh screen button.

ZOOM-function. Zoom in on any part of the graphs by holding down the left mouse button and move the mouse to select the area to be viewed. Release the left button when the selection is done, and the zoomed-in selecton will show. To return to standard display, press the Refresh screen button or click the right mousebutton anywhere in the Graph window.

Mark zoom area:

Release left mouse button and view zoomed area.

By moving the mouse while holding down the right mouse button, a vertical line and a digital readout is shown; move the mouse left/right and the horsepower, torque + Bmep under the line's crossing point with the graph is displayed.

To use the above mentioned 2 functions, the mouse pointer needs to be inside the black graph window.

To print the graphs, press the "Print" button, and select how many lines of remarks are to be printed with the graphs. A standard Windows printer dialog box is then shown.

Test.Test.Test.Test.

In this tab, you set up test-specific parameters and start a test.

1. Gearbox type. Click relevant type of gearbox.

2. Rpm at 100 Kph

Manually input the Rpm at 100 Kph (only for Fixed Gearing Vehicules)

3. Test parameters.

No RPM registration, select this option to run the test session without the Rpm pickup active.

720 - 360 - 180 and User defined degrees, sets the duration crank degrees between each impulse the Rpm pickup

registers. If you are not certain about the proper ignition sequency, the readings will be either zero or numbers that are

obviously wrong. Just click another option and do a rev. counter check until the "right" numbers show

4. Start Test Buttons. Start Test will start an ordinary Test sequence.

Preset Rpm Test will use the Preset Rpm Value to determine the Rpm/Speed relationship (only of use on Fixed Gearing Vehicules)

5. Rev. counter check: For a quick check of the rpm-function; press the "rev. counter check" button go to the Speedo page and rev the engine. This way you can check the rpms without performing an actual test. Close "Speedo" page by

pushing remote test button.

6. Number of Runs in a Test session.

1 to 3.

7. Record from analog channels.

Select the analog channels that will be active during the test session. Using t.ex a lambda unit, this will normally be

channel 1 and/or 2. NOTE: If no channels are checked, no analog data will be recorded.

Channels 1 and 2 are displayed on the horizontal display on the Speedo screen. In most cases, these two channels are

used for the the Wideband Lambda sensor, but can be configured to be used to your preference.

To perform a Test

Click the "Start Test" button. A screen will show: "start new test", click "yes".

Speedometer screen will show.

With variomatic:

Press remote button to start test run - the LED digit will show "1", indicating that run "1" is active. Immediately gas the bike to obtain run-data.

Press remote button to end test run. To make further runs, repeat above procedure. The LED digit will show a higher nunber "2" or "3"

To get the data showing how the variomatic engages, it is essential that you click the remote before gassing the bike.

With fixed gearing:

On the roller, with the engine started, work the bike through the gears to choose the gear you want to use during testing. Keep the engine speed at the rpm, at which you want to conduct the test (normally where the engine starts running

smoothly) Click the remote button - LED digit will show "1" - and immediately turn the throttle.

Press remote button to end test run. To make further runs, repeat above procedure. The LED digit will show a higher nunber "2" or "3"

We advise to use top gear roll on testing instead of working your way through the gears in all-gear testing.

GENERAL STEPS:

After performing the three runs in a test session, open the "remarks" tab, where remarks can be made to the test session just performed. The test session can then be saves as a file for later viewing and comparison.

If you do not want to perform all 3 runs in a test session: press the remote slowly and repeatedly ( the LED on the monitor will show "2" and "3") and then open the "remarks"-tab.

It is important to understand that the remote button function by forwarding the program to the next step in the testing procedure (press one time to start test run 1, press again to stop test run 1, press again to start test run 2, and so on) There is no need to enter remarks and spend time on arranging files if the test performed is not perfect. Therefore this

program is designed to let you first perfom the test, and then save and organize it.

FileFileFileFile

Here you will find the functions to save, handle and read tests. The first time you use this function after starting the program, it will open the folder specified in the Setup page -> Name

of initial test folder function.

Loading test sessions:

To load a test session, you navigate to the folder were the file is located, then mark the file in the right window and click

on the "test session"button that corresponds to the test session location into which you want to load it.

We strongly advise that you make a folder hierarchy that follows the bike make, model and year closely. This will make

your daily works much easier.

Saving a test session:

To save a just performed test session, press the Save session 1 button and a standard Windows Save As dialog box will

be displayed. Move to the folder in which you want to save the test session.

Remarks.Remarks.Remarks.Remarks.

Test session 1 is the active session and remarks can be entered and edited

Test session 2, 3 and 4 are read-only.

Make it a habit to always type descriptive, standardized remarks to the tests you make.

Instead of typing in the motorcycle make you can choose it from the Bike make dropdown list.

Test session 1 can be saved from this tab also.

AnalogAnalogAnalogAnalog

In this window you can view the recordings from the 5 analog channels shown as graphs.

If you have several different left side scales, you can switch between them by marking the corresponding Left scale -> Channel X button.

The right-hand mouse button has the same function here as in the Graph window: hold it down and move the mouse and a digital display with Speed and Rpm shows.

It is possible to zoom the window horizontally, and to change the power graphs representation from power to speed translation with the V. scale selection.

Because the horizontal scale in this window is timebased, you can move the graphs independently of each other with the left/right Move test 1-4 arrow buttons to syncronize them with each other. The Reset tests button resets all the tests to their original positions.

A/D Settings.A/D Settings.A/D Settings.A/D Settings.

THIS FUNCTION SHOULD BE USED ONLY WHEN CHANGING OR ADDING ANALOG DATA INPUT SOURCES

ALWAYS REFER TO THE RESPECTIVE MANUALS BEFORE CHANGING ANY VALUES

The left hand side of the window lets you change the scale in the analog the window to suit the type of recordings you make.

Use the Convert values 1-5 windows to change the parameters for the individual channels.

The input voltage to the analog/digital converter must be between 0 and +5 volts.

The + - factor moves the graph up and down in the display window. These factor values are in screen pixels.

You can set the time delay on a channel to synchronize the recording with the test run, this is important if you use a CO or 4-gas instrument, because the tube between the exhaust and the instrument gives a delay depending on the tube's length.

The invert checkbox turns the channels graph upside down.

If you press the "Save settings" button, both the conversion values and the scale values are saved to disk.

The numbers shown on screen above is for the MJPower Engineering NTK Pro series wideband Lambda probe.

Power On / Off, turns off the controller unit and the +5 volt supply to the Roller and Rpm pickups. Reset button restarts the controller and is also used in combination with the button on the back side to install new firmware. Sensitivity knob adjusts the trigger level for the Rpm Pick-up clamp. If an adjustment below 9 o'clock or above 3 o'clock is needed, try to reverse the clamp direction on the primary ignition wire or choose another wire with a better signal. Led: Green for power on, Red turns off when the infrared roller sensor is interrupted ( meaning it will blink quickly during a test run), Yellow blinks slowly when Rpm signal is recieved. Back side:

Power Correction FactorsPower Correction FactorsPower Correction FactorsPower Correction Factors

The power output of an internal combustion engine is significantly influenced by barometric pressure, ambient air temperature, and air humidity.

lower ambient barometric pressure reduces the density of the air, thus reduces the amount of oxygen filling the cylinder for each cycle, resulting in lower power output. Conversely, higher barometric pressure increases power.

lower ambient air temperature results in increased density of the air, thus increases the amount of oxygen filling the

cylinder for each cycle, resulting in higher power output. Conversely, higher air temperature reduces power output. lower air humidity (= less water vapour) leaves more room for oxygen per cubic foot of air, thus increases the amount of

oxygen filling the cylinder for each cycle, resulting in higher power output. Conversely, higher air humidity reduces power output.

Several Standards organisations have determined methods for estimating engine power under reference conditions.

The best known organisations are:

ISO (International Standards Organisation), SAE (Society of Automotive Engineers), ECE (European Community), JIS (Japanese Institute for Standardisation) and DIN (Deutsche Industrie Norm)

There are power correction standards for gasoline and Diesel engines, for applications in road vehicles, stationary engines, or marine engines, etc. For a motorcycle dynamometer, relevant standards are those generally intended for gasoline engines in road vehicles and those specific to motorcycles.

NOTE—Power correction standards try to estimate what engine power would be under reference conditions. They cannot actually calculate exactly what power output would be. The greater the difference between the ambient conditions during the test and the reference conditions, the greater the error in the estimate. Most power correction standards include limits on their applicability. This limit is typically +/- 7%. This means if the correction factor is greater than (>) 1.070 or less than (<) 0.930, the corrected power numbers are not officially considered to be acceptable, and the test should be performed again under conditions which are closer to the reference conditions.

For private applications this is less of a problem, and the corrected power numbers are still the best basis for comparisons. However, please keep this into consideration when comparing test results obtained under considerably different test conditions.

SAE—The SAE standard applied is the SAE J1349 standard of June 1990. Power is corrected to reference conditions of

990 MB. of dry air and 25 C. STP—The STP (also called STD) standard is another power correction standard determined by the SAE. This standard

has been stable for a long time and is widely used in the performance industry. Power is corrected to reference conditions of 1013 MB. of dry air and 15.5 C. Because the reference conditions include higher pressure and cooler air than the SAE J1349 standard, these corrected power numbers will always be about 4 % higher than the SAE J1349 power numbers.

ECE—The ECE standard is based on the European Directives. Power is corrected to reference conditions of 990 MB. of

dry air and 25 C. DIN—The DIN standard is determined by the German automotive industry. Power is corrected to reference conditions of

993 MB. of dry air and 20 C. With the advent of European legislation and standards, national standards such as the DIN (formerly widely used) are now less significant.

NOTE There is a tendency for all those standards to converge. The only world-wide power correction standards at this time are the ones determined by ISO. For internal combustion engines in road vehicles, this is the ISO 1585 standard. The current SAE J 1349 and ECE standards are nearly identical to the ISO 1585 standard.
