DescriptionThe whole story▼
The JP MJ 001 improves the SuperSport 939's throttle response and smoothness, which is the manufacturer's claim in full and a considerably more honest one than most.

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.
Type Approval
In markets where the fuelling forms part of the motorcycle's emissions approval, altering it puts the machine outside its approved condition. That is a legal question rather than an engineering one and it is worth settling locally.
Altitude and Air Temperature
The standard controller already compensates using its own sensors, and the module's correction is applied on top of whatever it decides. Riding somewhere high or hot does not require anything to be changed.
Model-Specific Wiring
JetPrime supplies the harness for the chosen motorcycle with the correct connectors moulded on. It is the part of the product that costs the most to develop and the part nobody thinks about.
Two Products, One Catalogue
JetPrime sells this alongside a programmable unit at a considerably higher price. The choice is between a curve somebody else worked out and a curve the owner works out themselves.
No Procedure Afterwards
Nothing to pair, calibrate or reset. The engine is started and the correction is already in place, which is unusual enough among electronic parts to be worth stating.
A Sensible First Modification
It costs less than a set of tyres, takes an evening and can be undone completely. As an entry into modifying an injected motorcycle there are considerably worse places to start.
The Injector Itself Is Unchanged
No hardware is replaced. The standard injectors, fuel pump and pressure regulator all continue exactly as they were, which keeps the fuel system entirely factory.
