Measure Hp and Tq using your CSV datalog.<\/strong><\/p>\n\n\n\n

Measuring your car’s torque and horsepower has never been easier, now that you can do it with the help of your mobile device and this digital Dyno. You just need to open one of your datalog of a pull, and Log Dyno will do the rest.<\/p>\n\n\n\n

You can use any CSV or MSL OBD datalog file that contains RPM data which is needed to measure Horsepower and Torque. You can also use SPEED data from GPS performance measurement devices such as VBOX and RaceBox and RaceBox mini.<\/p>\n\n\n\n

From the torque curve, the app is also able to determine the optimal gear shift points to ensure maximum acceleration. This makes sure you know when to shift, so you always have the most possible power at the wheels.<\/p>\n\n\n\n

Compare multiple measurements!<\/p>\n\n\n\n

You can save each one of your Dyno measurements, and compare them, or just analyze them interactively.<\/p>\n\n\n\n

What datalog files can be used?<\/strong><\/p>\n\n\n\n

\u25cf JB4
\u25cf MHD
\u25cf ProTool
\u25cf COBB
\u25cf ProTool
\u25cf Bootmod3
\u25cf and any other CSV datalog with RPM data or GPS Speed<\/p>\n\n\n\n

This is the easiest way to have your torque and horsepower measured with a virtual dyno using only your mobile phone and your datalog. You can see if your mods or tune work right away, and compare them.<\/p>\n\n\n\n

\u2605Log Dyno has been compared to multiple real life dyno sheets, and measurements were spot on, with multiple different vehicles\u2605<\/p>\n\n\n\n

How does it work?<\/strong><\/p>\n\n\n\n

#1. Datalog your vehicle<\/strong>
Take the datalog just like a dyno pull, in one given gear, from low rpm to high rpm. Try to avoid wheelspin as it can cause spikes in the graph.<\/p>\n\n\n\n

#2. Set up your vehicle data<\/strong><\/p>\n\n\n\n

The dyno app requires some data about your vehicle. You\u2019ll be asked to set values for the following:<\/p>\n\n\n\n

\u25cf Car Name
\u25cf Weight
\u25cf Tank Capacity
\u25cf Tire Size
\u25cf DT%
\u25cf Drag Coefficient
\u25cf Frontal Area<\/p>\n\n\n\n

#3. Share the results!<\/strong><\/p>\n\n\n\n

You can share your results right from the virtual dyno measurement page to basically any app or post it to any social network or email it. Of course, you can just save the results in your phone gallery too.<\/p>\n\n\n\n

For more detailed information, scroll down to the bottom of the description and see the User’s Guide.<\/p>\n\n\n\n

How accurate is the dyno measurement?<\/strong><\/p>\n\n\n\n

If you have set your vehicle data correctly, the results our dyno app gives will be the same as the results a real dyno will give you. Also, keep in mind that wheelspin may result in spikes in the graph. If you are unable to avoid it, you\u2019ll still get accurate results, you just need to ignore the spikes.<\/p>\n\n\n\n

The best thing about our dyno app is that you can see right away how your mods work after datalogging. Now, you don’t have to go to the dyno if you want to measure any small modification or just never had your car’s power measured. You can see right away how your mods or tune work after datalogging. You can dyno unlimited times and unlimited vehicles for the fraction of the price of a dyno measurement.<\/p>\n\n\n\n

You have to set your car up, how much it weighs, its tire size, the gear ratios, and also what your car drag coefficient and frontal area are, which the app will help in determining.<\/p>\n\n\n\n

Based on your car data and environmental values, the app calculates a torque and horsepower curve from the datalog, which you can analyze. The app also points out the peak values, and you will be able to see at what rpm you made the most torque and the most power.<\/p>\n\n\n\n

Corrections:<\/strong>
\u25cf Uncorrected
\u25cf SAE J1349
\u25cf STD
\u25cf DIN 70020
\u25cf ISO 1585<\/p>\n\n\n\n

Power Units:<\/strong>
\u25cf WHP
\u25cf BHP
\u25cf PS
\u25cf KW<\/p>\n\n\n\n

Torque Units:<\/strong>
\u25cf LB-FT
\u25cf NM
At the wheels or at the crank<\/p>\n\n\n\n

The app is widely used among N54 N55 and S55 Tuners with great results backed up by dyno runs.<\/p>\n\n\n\n

You can datalog either via OBD or your piggyback tuner, all you need is a CSV file. You can also use a GPS device to datalog SPEED for measurement.
