DescriptionThe whole story▼
The JP MJ 001 sits between the Dorsoduro 900's loom and its injectors and adjusts how long each one stays open, which is the whole of what a power module does.

A Supermoto With Injection
The 896 cc vee in a tall flat-barred chassis is ridden on and off the throttle constantly, which puts the transition fuelling under more scrutiny than anywhere else.
Preset, Not Programmable
There is no laptop, no software and no session on a dyno. JetPrime supplies the module with a curve worked out for that engine, and the owner's job ends at plugging it in. That is the whole difference between this and the programmable unit alongside it.
No Laptop Required
JetPrime works out the curve for that engine and ships it in the module. There is no software to install, no cable to buy and no afternoon spent learning an interface, which is the entire point of the preset version.
No Adjustment, By Design
Some owners want a dial to turn. This module deliberately does not have one, because a curve worked out for the engine is more reliable than one worked out on a road by somebody guessing.
No Settings to Get Wrong
A preset curve cannot be misconfigured, cannot be lost when a battery is disconnected and cannot be blamed for a fault six months later. That reliability is the argument for buying the simpler of the two units.
A Curve, Not a Setting
The correction varies with load and engine speed rather than being a single percentage. That is what separates a developed module from a resistor in a box, and it is why it is sold per model.
Heat
Under a seat is warmer than most owners assume once an engine has been working. The module is built for it, but pressing it against a subframe rail that carries exhaust heat is still worth avoiding.
The Emissions Cycle in Practice
The test runs at defined speeds and loads, and manufacturers naturally pay closest attention to those cells. A rider who spends time in exactly those cells feels the compromise most.
