A Note on TunerStudio Licensing

You do not need TunerStudio Pro to tune your motorcycle. The Impact ECU is fully tunable with the free version of TunerStudio.

That said, Pro adds features that speed up the tuning process. A Pro license is a one-time purchase tied to your tuning computer — not to a specific bike — so you only ever buy it once.
