Dyno-developed base maps.

Performance tunes matched to your Harley and installed parts.

Powered by JCES™ J-Code Evaluation System — evaluates your bike, tuner, and installed parts against available Precision Basemaps.

How it works

Enter your VIN

We verify the bike so you don't buy the wrong map.

Choose your tuner

Select the tuning device you own so the correct file format is shown.

Pick your basemap

Filter by cam, exhaust, heads, intake, injectors, and more so JCES can show Precision Basemaps for your combination.

Create your free customer account and download

When you are ready to buy, create a free customer account — not a shop membership — then accept terms and download. These are dyno-developed Precision Basemaps, not a replacement for a complete professional dyno tune.

JCES™ What is JCES™?

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 does not replace a professional dyno tune. It is why Basemaps.net can show you the files that belong to your combination.

Map-sourcing is not free labor. See how much billable time a matched Precision Basemap can put back into the bay.

1. End lift lockdown

After a cam or exhaust job, the bike often sits on the lift while someone hunts a file. Square footage is money. Find My Tune takes the VIN plus the cam and exhaust on the bike and returns a matching Precision Basemap to flash. The bike can start and roll off so the next mechanical job can take that lift.

2. Shorten the dyno, do not skip it

A generic file makes the tuner build volumetric-efficiency tables from scratch — heat, fuel, roller wear, and your most skilled tech for hours. A Precision Basemap comes from a real dyno session for that parts combination, so the dyno is for weather, fuel, and the last refinement. It must still be dyno tuned for best results.

3. Flash without waiting on one guru

JCES™ evaluates the VIN, tuner, and installed parts so an intermediate tech can flash the cataloged file. That does not replace a master tuner on the dyno. The same matching rules run for every published file.

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.

Estimates are for planning only. Actual time savings depend on the motorcycle, parts combination, shop workflow, tuner experience, and job complexity. Precision Basemaps are dyno-developed calibration files and are not a replacement for a complete professional dyno tune. They must be dyno tuned for best results. How shops use Basemaps.net →

It is not a replacement for a professional dyno tune or motorcycle-specific verification.
These products are raw data files only. They require independent third-party hardware and flashing software that Basemaps does not sell or control. You assume all risk of hardware failure, protocol errors, and vehicle damage during flashing.
These calibrations are intended strictly for closed-course, off-road competition use. You assume all regulatory and legal compliance responsibility for their installation and operation.
You assume all risks of use, installation, and operation.
