DescriptionThe whole story▼
The JP MJ 004 is the simpler of JetPrime's two fuel units for the R1200RS: a curve somebody else worked out, rather than one the owner has to develop.
Key Features
- BMW R1200RS (2014–2018)
- 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 Sports Tourer Boxer
Half a fairing, lower bars and the same water-cooled twin. The RS is ridden faster than the GS and at more consistent throttle openings.
Cold Starting Is Untouched
Warm-up enrichment is a function of the standard controller and the module does not interfere with it. A motorcycle that started badly before will start exactly as badly afterwards, because that is a different problem entirely.
It Does Not Touch Ignition
Advance and retard are the standard controller's business. A fuel module cannot alter them, which limits what it can achieve and also removes the commonest way to damage an engine electronically.
After a Silencer
The standard controller's closed-loop correction covers a narrow band and gives up outside it. A module extends the correction into the part of the map where a freer exhaust actually changes things.
Somewhere Dry and Secure
Under the seat on most bikes, occasionally under the tank. It needs to be where water does not sit and where the harness is not under tension when the suspension moves.
The Second Thing
Steady-speed hunting disappears or reduces. On a motorway at a constant opening a lean cruise setting produces a slow surge that riders stop noticing until it stops happening.
Winter Storage
Nothing about the module objects to a cold garage and there is no battery in it. It draws no current when the ignition is off and needs no attention over a layup.
A Single Curve, Not a Compromise
Because the module is developed for one engine, the correction can be shaped for that engine's behaviour rather than averaged across a range of machines with different requirements.
