Do you sell Milwaukee-Eight / M8 tunes?

Yes. The catalog includes Milwaukee-Eight Touring and Softail Precision Basemaps for Power Vision, PV3, and PV4. Match by VIN. They must be dyno tuned for best results.

Is Basemaps.net a GIS or map-tile website?

No. Basemaps.net is a Harley-Davidson tune-file catalog. A basemap here is a Precision Basemap by Matt Smith, not an Esri, CARTO, or USGS map layer. It must be dyno tuned for best results.

Harley M8 tune files & Milwaukee-Eight maps

Looking for an M8 tune or a Milwaukee-Eight map? Those are the Harley-Davidson tune files most late-model Touring and Softail riders want. On Basemaps.net they are sold as Precision Basemaps — .pvt / .djt files for Power Vision, PV3, and PV4.

Which bikes

Milwaukee-Eight Touring is generally 2017-and-later. Milwaukee-Eight Softail is generally 2018-and-later. Older Big Twins in the catalog are Twin Cam. The VIN, not the tank badge, decides what you actually have. Touring, Softail, Dyna, and trike coverage is Big Twin only. Sportster and V-Rod stay out of scope.

How to get an M8 tune

Find My Tune — 17-character VIN.
Choose Power Vision, PV3, or PV4 so you get the matching file format.
Select cam, exhaust, and intake if you know them.
JCES evaluates the combination and shows available Precision Basemaps.

JCES does not rewrite the file in the browser. It is why you are not guessing which M8 map belongs to your 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).
