Frequently Asked Questions

Do I need a separate license to tune multiple bikes?

MasterTune licensing is tied to the interface. You can license it for one or two vehicles — the interface locks to the first vehicle programmed.

Is the software included or do I download it?

The MasterTune software is free to download at MasterTune.net/GettingStarted. The interface hardware is what you purchase here.

Can I use this on my 2023+ Harley?

This interface is designed for 2012-2022 Delphi-equipped models. Newer bikes may use different ECM platforms — verify compatibility before ordering.

What do I need besides this interface to tune my bike?

A Windows-based laptop or PC. The Bluetooth interface connects wirelessly to your ECM for tuning and data logging.

Can I save my factory tune and restore it later?

Yes — the software stores your original factory calibration and allows you to save and restore previous configurations at any time.
