Harley tune files for Touring, Softail & Dyna
The catalog is Harley-Davidson Big Twin. That is what you can actually buy. We do not list a tune for every tank badge on the internet — we list files we can match to a real motorcycle.

Families in the catalog
- Touring — Street Glide, Road Glide, Road King, Electra Glide, and related FLH / FLT platforms, including many CVO and trike conversions when the VIN and vehicle class allow it.
- Softail — Milwaukee-Eight and Twin Cam Softail platforms in the catalog.
- Dyna — supported Dyna years that exist as published Precision Basemaps.
- Trikes — factory trikes and documented motorcycle-to-trike conversions. The VIN is still a motorcycle VIN; the catalog decides whether a map is offered.
Out of scope
Sportster and V-Rod are not in this catalog. A search that only names those platforms will not grow a file we do not sell.
Do not shop by marketing name alone
“2020 Street Glide” is not enough. Two bikes with the same badge can need different files. Enter the VIN, choose your tuner, and tell us the parts that are actually installed. That is how you get the Harley tune file that belongs to that motorcycle.

Where every Precision Basemap comes from
Every Precision Basemap on Basemaps.net was created from a real dyno session by Matt Smith, owner and architect of Basemaps.net — not generated, simulated, or otherwise made artificially. He built this catalog to help the entire tuning industry share those files.
Each file is sold as it was the day it was created, for the exact combination of parts on the motorcycle in that session — the real deal, nothing turned down. Before a file is offered for sale it passes several quality checks in our system. The catalog operating system applies the same matching rules to every published file so the same VIN, tuner, and parts combination is evaluated the same way. The file must still be dyno tuned for best results.
If you have a concern — or want to give praise
After you buy and download, open your account. Each purchase has Leave Feedback. Use it to rate the Precision Basemap, note a concern, or say what went well. That form is for quality review. It is not phone support and does not open a ticket.
If Find My Tune has no file yet
When the catalog has no match for your bike and parts, you can join the Precision Basemap Waitlist on that empty-results screen. Leave your email and the combination you searched. We email a purchase link when that file is published. That is not a custom map emailed instead of a catalog file, and it is not offered for platforms we do not sell (Sportster and V-Rod).
