The VersaTune software is such a user friendly software compared to the competition. It’s laid out very nicely with easy to use drag and drop boxes to choose what to log and even runs and works on my Windows 10 touchscreen tablet that I keep in the car for easy tune swaps. It is also not locked to a single computer like other tuning softwares, which is a bonus in my books, especially for how often I’m upgrading devices.

On the Versatuner website there are downloadable pre-tuned files that you can add to the software. Is this the same tuner from their website? Can you use those files with this software?
