DYNOTEST sendiri...?? mari masuk & pelajari
Biaya DYNO MUAHAL....??
Lokasi DYNO Jauuuhhh dari tempat tinggal...??
Kenapa nggak dyno sendiri aja & Murah.... mari download softwarenya & Aplikasikan ke kendaraan anda...
Pasang Recorder & Adaptor,.. nyalakan motor anda..jalan gigi 4 @rpm rendah... langsung Bejek Abiess sampai Limiter.... abies ntu tinggal edit hasil rekaman di software... masukan data2 pendukung..
o iya, Adaptornya ambil Input bisa dari Koil, Dynamo/Alternator Signal, Microphone, atau Spedometer Digital.

GSF Dyno - The Dynamometer Software for Well-Founded Tuning
GSF Dynamometer software in combination with a commercial sound-recorder allows for making power/torque curves of a motorcycle (or car). Dyno runs are done (recorded) on the street and analysed on the PC at home. Dyno runs are essential for tuning and correct jetting of the carb. Here you found the minimum-cost dynamometer. All you need is to download the dyno software, a sound recording system and I suggest to build the voltage divider as described below.
softwarenya Download dimari..
its FREE SOftware..
The idea for the GSF Dyno software was to measure the power curve of a motorbike just by recording the sound of the engine with a commercial sound recording system like Mini-Disc or MP3 recorder. The engine rotation and its time derivative (acceleration) should be calculated from the recorded sound. Knowing in addition the total mass (vehicle, driver, gas...), the Cd value (drag coefficient) and the gearing ratio would then be enough to calculate the power output with respect to engine rotation.
However, recording the sound or noise of the engine is not very easy. Usually, a lot of other noise will also be recorded making the analysis difficult. Furthermore, usually microphones are unable to record sound-frequencies of less than 50Hz (3000RPM on a two stroke single cylinder) and in addition the records are often overdriven.
The GSF Dyno software still can handle recordings done with microphone, however the success is not sure. An eraser tool was implemented to allow the user to erase noise from the record. Much better results can be obtained using a voltage divider. With it the alternator (and its changing frequency) can be recorded and replace the sound signal. The AC voltage produced on motorbikes is directly proportional to the engine revolution.
This dyno software work very well on different Vespas, Lambrettas and for sure also on other vehicles. Recently I tried it with a microphone in the passenger cab of my car - it worked :-) Here is the output of carburetor jetting session of my tuned 177ccm Pinasco Vespa:
ni salah satu contoh yg sudah saya terapkan tuk Dyno Busi Timor..
jika ada pertanyaan silahkan... nanti akan saya bantu..

The Main Window
The main window is composed of several buttons which allow the user to set all the parameters needed by GSF Dyno software to calculate the correct curve.
Let's describe the buttons according to their numbers in the figure above.
1. Type in the name of the wav-file you recorded during the run, or
2. Browse your directories to find and set the wav-file name.
3. If this checkbox is activated then an other pop-up will be displayed during the calculations where you can select the range of the file which should be used for the analysis (see next section).
4. Activate this button to add the wav-file name to the comment.
5. Select the type of signal for the left channel (Dynamo / Wheel Sensors / Inertia Drum / Ignition / Off).
6. Same for the right channel (Dynamo / Wheel Sensors / Inertia Drum / Ignition / Off).
7. Here all the physical parameters needed for the calculation are asked:
# Total Weight [kg]: Thats the weight of the vehicle plus everything what was loaded on (driver, petrol...)
# Cd Value: Drag coefficient for your vehicle. Most of us has to guess that. Somewhere between 0.3 and 1.
# Frontal Area: The frontal area is needed together with the Cd value to calculate the drag.
# Gear ratio: The ratio between the wheel and the engine. If the engine makes 6 revolutions while the wheel makes only 1 than the ratio is 6. Pressing this button shows a list with many Vespa gearing ratios.
A mouse click onto an item of the list activate the item and its gearing ratio is transfered to the main program window. Use the "Remove" button to remove an item from the list or the "Add to list" button to add the gearing ratio typed in to the text fields to the left of the "Add to list" button.
# Wheel Circumference: Circumference of the tire. Pressing this button open a Tyre Circumference Calculator.
Type in the spcification of your tyre to calculate it's circumference. Pushing the 'Calculate' button calculates the circumference and transfers it to the field on the main panel. However, the tyres often differ form the theoretical circumference value, therefore an list of measured circumferences can be reached by pushing the "Tyre List" button. This list is similar to the 'Gearing Ratio List'.
# Filter length [s]: That smooth the output curve. Higher values make smoother curves. Smoothing is needed due to the finite (and coarse) resolution of the numerical calculation. Choose a value which produce similar curves you are used to see from a commercial dyno.
# Dynamo/Mic Signals per Rotation: If you recorded the dynamo/alternator (or microphone), type in its amount waves per motor rotation. If you don't know it try some numbers until you get the right RPM range. For the microphone recordings: 2Stroke 1Cylinder: 1, 2Stroke 4Cylinder: 4, 4Stroke 4Cylinders: 2.
# Drum Sensors / Wheel Sensors: This button switches between the amount of Drum Sensors and Wheel Sensors, depending on the signal you use. If you use a digital speedometer signal, than this will be 1 due to one magnet on the wheel - increasing this value (i.e. increasing the amount of magnets on the wheel) will result in more accurate results.
# Air Temperature: Small changes in power output can occur according to air temperature changes. To take that into account type in the air temperature during the run. [DIN 70020]
# Air Pressure: Same background as for Air Temperature.
# Momentum of Inertia: Used for inertia drums.
# Drum Circumference: Used for inertia drums.
# Minimum RPM: Minimum RPM to use in calculation.
# Maximum RPM: Maximum RPM to use in calculation.
8. Press here when everything is set right to calculate the curve.
9. Press to change the color of the curve to be plotted. However, it can also be changed afterwards in the output graph.
10. If this checkbox is activated the curve will be cut after the maximal velocity was reached.
11. Pushing this button clears the internal memory of the software.
12. Write some comments to the curve here.
13. The title of the output graph.
14. Choose what the software should display on the X-Axis
menu channel 1
15. Choose what the software should display on the Y-Axis. Note that power is in kW or continental Horse Power (PS,CV not HP).
menu channel 2
16. Activate it to add the physical parameters to the comment.
17. Load the parameters from file.
18. Save parameters to file. If you save them in the file named gsf_dyno_start.cfg they will be automatically loaded when you start GSF Dyno the next time.
wah TSnya kena timpuk bata merah
Waduh, ane gak ngerti gini-ginian. Yg udah2 kalo ngomongin Dyno & HP pasti muncul bermacam2 persepsi.
Menyimak dulu aja deh
lumayan nih buat pembelajaran...sip
coba bs buat mobil hehe..
om coen, bsa buat mobil gk?
bagus jg nie, secara di medan kagak ada dyno... hehehehehehehe
wahh adaptornya gmn tuh om?jelasin donk...
wiw, sepertinya agak2 ribet ya om, tapi lumayan juga tipsnya
perlengkapan apa saja yg dibutuhkan selain laptop dan kendaraan?kabel2,sensor2,dll?
bisa dijelaskan lebih lanjut..
apapun inovasinya..asal buat kemajuan gw dukung d
Iya om coen....bagi ilmunya jgn setengah2 dong...gw salute buat om coen.. tp ada jg yg sirik ya...sabar om
