Tuning License for one Harley-Davidson motorcycle and Diag-4-Bike software HD-V22.1 or higher

Diag-4-Bike software has the option to tune various motorcycles for race use. This requires a Tuning License to unlock the ECM. One Tuning License works for an unlimited number of tuning sessions for one single motorcycle. Tuning Licenses only work with a Multi-Dongle as supplied with all new software packages since 2022. The Multi-Dongle allows internet connection for the activation of the license key in the Diag-4-Bike software. For those who have purchased a Diag-4-Bike software update online a Multi-Dongle is also available separately.
