No, the **PV4-15-04** is specifically designed for **Gen 2 M8 models (2023.5+)** and will **NOT** work on older Gen 1 M8 motorcycles.
For **Gen 1 M8 models** (2017-2023), you'll need the **PV4-15-03** instead:
- **Power Vision 4 for Gen 1 M8** - SKU: PV4-15-03
- Compatible with 2017-2023 Harley-Davidson M8 models
- Uses different tunecompat software levels than Gen 2
The key differences:
- **Gen 2 M8** (2023.5+): Uses PV4-15-04, tunecompat levels starting with 51/48/45
- **Gen 1 M8** (2017-2023): Uses PV4-15-03, tunecompat levels starting with 28
Each generation requires its specific hardware due to different ECU security and software architecture. Need help finding the PV4-15-03 for your Gen 1 M8?
