DescriptionThe whole story▼
The JP MJ 004 is the plug-and-play fuel module for the S1000 XR: a curve worked out for that engine, supplied with the harness the motorcycle needs.
Key Features
- BMW S1000 XR (2015–2019)
- Preset fuel module, no programming required
- Corrects the mixture without remapping the original electronics
- Plug-and-play with model-specific wiring
- Around 200 g, fitted in an evening
- Unplugs at any time, nothing is written to the motorcycle
A Four in a Tall Chassis
The XR carries the sports engine at touring speeds for long distances, which means most of its life is spent at small throttle openings in the middle of the rev range.
Diagnostics Still Work
Because nothing is written to the original controller, the service history stays readable and any fault the motorcycle develops is reported normally. A masked fault memory is one of the real costs of the alternatives.
Removal Before a Service
Five minutes with the seat off returns the motorcycle to standard. Whether that is necessary depends on the dealer and the term, but the option existing at all is part of what the product is.
Warranty, Practically
Unplug it, put the original connectors back together and the motorcycle is standard. Most owners do this before a service and reconnect it the same evening.
What It Will Not Do
Raise a rev limit, alter ignition, change a rider aid or repair a worn sensor. Being clear about that is more useful than a longer list of what it does.
Working With the Sensor
The oxygen sensor loop keeps trimming where it trims. The module adds its correction to that result rather than replacing it, which is why nothing conflicts and nothing is reported.
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.
Big Singles
A thumper is the clearest case of all. With one cylinder and one firing event every other revolution, any hesitation at small openings is felt directly through the chassis.
