DescriptionThe whole story▼
The JP CJP 012H gives a track-prepared SuperSport 939 a fuel map that can follow the fuel, the weather and the exhaust rather than being fixed at the factory.
Key Features
- Ducati SuperSport 939 (2017–2020)
- Fully programmable fuel map, written on a PC
- Complete two-axis management: engine speed and load
- For engines with an aftermarket exhaust or air filter
- Plug-and-play with model-specific wiring
- Unplugs at any time, nothing is written to the motorcycle
The Testastretta 11 Degree
Ducati's road-biased twin uses a small valve overlap to make it smooth at low revs. It is the most civilised engine the marque builds.
Programming Over USB
A cable from a laptop to the unit, the dedicated software on a Windows machine, and the map written in seconds. The motorcycle does not need to be running to receive it.
Two Owners, One Bike
The map lives in the unit, not in the rider. Anybody who rides the motorcycle gets whatever was last written, which is worth remembering on a shared machine.
Mapping at a Circuit
A laptop, a wideband and a session between runs. This is where a programmable unit earns its price over a preset module, because conditions change and the map can follow.
Safety Margin
Map slightly rich where the engine works hardest. The power difference is negligible and the consequence of being wrong in the other direction is not.
Full Throttle Last
It is a single line, it needs a dyno to read properly and it is the region a road bike visits least. Doing it first is a common and unproductive instinct.
Vibration
Electronics on a motorcycle fail from shaking rather than from getting wet. A body secured flat against a surface outlives one hanging on its own harness.
The Airbox Matters
Anything that changes intake flow changes the whole surface. Owners who modify the airbox after mapping have a mapping session ahead of them, not an adjustment.
The Cost of the Whole Setup
The unit, a wideband sensor and a bung welded into the exhaust. Together they cost less than a decent silencer, and without the sensor the unit is an ornament with a USB socket.
