DescriptionThe whole story▼
The JP MJ 004 is fitted to the F 800 ST to make an injected engine pleasanter rather than faster, and the description says exactly that.
Key Features
- BMW F 800 ST (2006–2016)
- 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
The Touring Variant
A taller screen, a more upright bar and the same belt-driven twin. The ST is the version people actually rode long distances on.
Against a Full Remap
Flashing the original controller changes ignition timing, rev limits and rider aids as well as fuelling, and it needs specialist equipment. A module is narrower, cheaper and reversible in a minute, which suits an owner who wants one problem solved.
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.
Service History Stays Readable
A workshop reads the standard controller and finds the standard controller. That is worth more on a motorcycle that will be sold than most owners realise while they still own it.
Reading the Fault Memory
Untouched electronics report honestly. On a machine with a flashed controller a diagnostic session is a negotiation; on one with a module it is simply a diagnostic session.
Compared With a Remap
A flash of the original controller reaches further and is harder to undo. This is the narrow, cheap, reversible option, and for most road riders it addresses the actual complaint.
A Long-Lived Component
There is nothing in it that ages: no relay, no moving part and no user setting to drift. Fitted properly it will outlast several sets of tyres without being thought about.
Second Hand Modules
They transfer between identical motorcycles because there is nothing stored in them that belongs to one machine. The harness is the part that has to match, not the module.
