DescriptionThe whole story▼
The JP MJ 008 corrects what a homologation map costs the F4RR 1000 at part throttle, which is where almost all road riding actually takes place.
Key Features
- MV Agusta F4RR 1000 (2011–2015)
- 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 Track Specification
Ohlins, forged wheels and a higher state of tune. The RR is the F4 bought by owners who intend to use the rev range rather than admire it.
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.
Where Manufacturers Run Lean
Cruise, small openings and the range the emissions cycle measures. Those are the conditions a test procedure examines, and they are also the conditions a rider spends most of their time in on a road.
Lambda Control Is Not Bypassed
The module works with the oxygen sensor loop rather than around it. Nothing is disconnected, spoofed or hidden, which is one reason the fault memory stays clean.
Nothing to Configure Afterwards
There is no pairing procedure, no calibration ride and no reset. The motorcycle is started and the module is already doing what it does.
Sequence With an Exhaust
Fit the silencer, ride it, then fit the module. Two changes at once tell the rider nothing about either, and the exhaust is the one that moves the mixture furthest.
If Something Goes Wrong
Unplug it and the motorcycle is standard. That single sentence is worth more during a diagnosis than any amount of documentation, and it is not true of a reflashed controller.
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.
