How Virtual Dyno Works

Collecting Data

Tools needed for data logging

To use virtual dyno, you need special tools to gather car data. The most common tool is an OBD-II device, which connects to your car’s computer. Pair it with tuning software like Cobb AccessPort or Hondata to record key details. These tools collect data like RPM, throttle position, and boost pressure for turbo cars. This data is used to create accurate performance graphs.

Why accurate data matters

Getting accurate data is very important for good results. You should log data on flat roads with little wind. Bumpy roads or bad conditions can mess up the data, giving wrong power and torque numbers. Always use the same road for testing to get consistent results.

Tip: Check your logging tools before starting. Broken tools can ruin your data.

Inputting and Analyzing Data

Uploading logs into the software

After collecting your logs, upload them into the virtual dyno program. It works with over 40 ECU types, so it fits most cars. Once uploaded, the software processes the data to make performance graphs.

How the software analyzes data

The software uses smart algorithms to study your logs. It looks at things like car weight, tire size, and gear ratios to calculate power. It also removes errors caused by bad roads or logging mistakes. This makes the results very accurate, often matching real Dynojet dyno results within 0-3%.

Making and Understanding Results

Creating performance graphs

After analyzing the data, virtual dyno makes graphs showing horsepower and torque. These graphs help you see how your car performs in different situations. You can change graph settings to compare results with Dynojet or Mustang dynos.

Using graphs to improve tuning

The graphs help you adjust your car’s settings. For example, if torque drops at certain RPMs, you can change the air/fuel ratio or boost pressure to fix it. By testing again, you can improve your car’s power and performance.

Note: Use the smoothing tool in virtual dyno to check graph accuracy. A power drop of less than 12-15 WHP between smoothing levels means the results are reliable.
