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 dynamometer. You just need to datalog one of your pulls in a given gear, and Log Dyno
will do the rest.
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.
What datalog files can be used?
● and others...
You can use any CSV or MSL file that contains RPM data which is needed to accurately measure Horsepower and Torque. This Android dyno app works flawlessly with MHD, JB4, and MegaSquirt logs, and since they have auto-logging, they are very convenient.
This is the easiest way to have your torque and horsepower measured with a virtual dyno using only your mobile phone and recent data logging information. You can see if your mods or tune work right away.
★Log Dyno has been compared to multiple real life dyno sheets, and measurements were spot on, with multiple different vehicles★
How does it work?
#1. Datalog your vehicle
Take the log 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.
#2. Set up your vehicle data
The dyno app requires some data about your vehicle. You’ll be asked to set values for the following:
● Car Name
● Tan Capacity
● Tire Size
● Drag Coefficient
● Frontal Area
Also, you’ll be able to choose which unit to work with and whether to see WHP, BHP, PS, and KW (WHP is default).
#3. Share the results!
You can share your results right from the virtual dynamometer test on basically any app or post it on any social network/email. Of course, you can just save the results in your phone gallery too.
For more detailed information, scroll down to the bottom of the description and see the User Guide.
How accurate is the dyno measure?
If you have set your vehicle data correctly, the results our dyno app gives will be the same as the results a real dynamometer will give you. Also, keep in mind that a bump or wheelspin may result in spikes in the graph. If you are unable to avoid such occurrences, you’ll still get accurate results, you just need to ignore the spikes.
The best thing about our dyno app is that you can see right away how your mods work after data logging. Now, you don't have to go to the dyno if you want to measure any small modification or just never had your car power measured. You can see right away how your mods work after data logging. You can dyno unlimited times and unlimited vehicles for the fraction of the price of a dyno measurement.
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.
After specifying for which gear you had the data log taken and specifying the driver, passenger, and possible cargo weight, you can open the CSV or MSL file.
After each measurement, note the humidity percentage, ambient temperature, and barometric pressure for accurate results.
Based on your car data and environmental values, the app generates a torque and horsepower curve, 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.
