DescriptionThe whole story▼
The JP MJ 004 corrects the mixture on the S1000R without touching the original controller, its adaptations or its fault memory in any way.

- Plug-and-play with model-specific wiring
- Around 200 g, fitted in an evening
- Unplugs at any time, nothing is written to the motorcycle
The Detuned Four
BMW softened the superbike engine for the roadster by changing cams and mapping rather than capacity. The result is a bike with more midrange and a flatter response.
An Evening's Work at Most
Seat off, tank lifted on some models, connectors separated, module plugged in and tied down. There is nothing to configure and nothing to learn afterwards, which is unusual for anything electronic on a motorcycle.
Not a Racing Part
There is no adjustment, no logging and no way to tailor the curve to one circuit. Riders who want that need the programmable unit, and JetPrime sells one alongside this.
Legal Position
Where fuelling forms part of the approval, changing it takes the machine outside its approved condition. That is a matter of local rules and it is worth knowing before rather than after.
Physically Small
About the size of a matchbox and around two hundred grams. On a motorcycle the difficulty is never the module itself, only finding a tidy route for the cable.
Cold Starts Are Not the Target
Warm-up enrichment is separate, standard and untouched. A machine that has always been reluctant on a January morning will remain exactly as reluctant.
The Question to Ask Yourself
Does the motorcycle irritate at small throttle openings? If the answer is yes, this is the cheapest thing that addresses it. If the answer is no, nothing here applies.
Six Cylinders
At the other extreme, an inline six is so smooth that a lean patch is easy to miss. The correction still applies; the rider simply has less to compare it against.
