Every Precision Basemap began with real dyno development on a real motorcycle. It was a completed calibration for the motorcycle used to develop it.
JCES™ stands for J-Code Evaluation System. Rather than making you guess which file fits, JCES evaluates your motorcycle, tuner, and installed components against available Precision Basemaps.
JCES is why Basemaps.net can show you the files that belong to your combination.
Basemaps.net is an online catalog of dyno-developed Precision Basemaps by Matt Smith. This is a file only. It requires a tuner in order to use it. A Power Vision, MadLad Solutions interface, ThunderMax, HP Tuners, or any digital license is not included or sold by Basemaps.net.
Create a free customer account and purchase Precision Basemaps individually. A dealer or shop account is not required.
Optional membership programs provide professional pricing and additional benefits. Membership is not required to buy a basemap.
Map-sourcing is not free labor. See how much billable time a matched Precision Basemap can put back into the bay.
Example, not a promise: five upgrade jobs a week, two hours recovered on sourcing and troubleshooting, at $120–$150/hour is $1,200–$1,500 a week in recovered labor — plus room to book more work. Type 20 maps/month and 2.00 hours in the calculator to see that week. Clearing the lift Friday still beats hunting a file until next week.
No catch. Pro total already includes the monthly fee.
Estimates are for planning only. Actual time savings depend on the motorcycle, parts combination, shop workflow, tuner experience, and job complexity. How shops use Basemaps.net →
Browse Catalog is exploration. Start with your parts, then narrow to your bike with the same questions the VIN check asks. Pricing and purchase need your VIN once for the JCES compatibility check.

Your VIN identifies the bike. Your parts describe the build.
Hint: Tap the picture that matches the tuner device you own. You can change it later if needed.
Other tuner options in development and coming soon!
Compare published Twin Cam and Milwaukee-Eight grind cards. Switch the engine family live — the three picks are shelf-scoped and clear when you change families.
Milwaukee-Eight lift is shown as published. This page does not assume a 1.625 rocker on M8.
Four events only — no lift. Use this when the grind is not in the list (a Crane still on the bike, a degree-wheeled unknown, etc.).
Pick up to three cams. Switch Twin Cam or Milwaukee-Eight without reloading.

Uses the first cam you picked (or the nearest published grind if you only entered events) to rank catalog maps. If we do not have that grind, we point you at the closest published intake close. Search by Bike still needs your VIN. This does not hide maps or add a checkout gate.
Estimates and published cards only. Duration, overlap, lobe centers, and LSA are derived when the four events exist. Missing numbers stay blank — never painted as zero. Not a valvetrain design tool and not a checkout gate. Must be dyno tuned for best results.
