DescriptionThe whole story▼
The JP MJ 008 is what an owner fits to the Tracer 900 after an exhaust, when the standard closed-loop correction has run out of authority.
Key Features
- Yamaha Tracer 900 (2015–2020)
- 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 Earlier Version
Before the name changed, Yamaha's triple tourer was the Tracer 900. Same idea, less electronics and a slightly rawer delivery.
The Loom Is Model Specific
The module is common; the harness that connects it is not. JetPrime supplies the wiring for the chosen motorcycle, which is why the catalogue lists machines rather than engine sizes and why a part from another model is not a shortcut.
The Original Controller Stays in Charge
Ignition timing, the rev limiter, traction control, the riding modes and every safety strategy remain exactly where they were. The module has no access to any of it and no interest in it.
Model-Specific Wiring
JetPrime supplies the harness for the chosen motorcycle with the correct connectors moulded on. It is the part of the product that costs the most to develop and the part nobody thinks about.
Oxygen Sensor Interaction
Nothing is disconnected and nothing is simulated. The standard trim loop continues to operate in the band where it operates, and the module's correction sits on top of the result.
Honest Diagnostics
A motorcycle whose controller has never been written to reports faults properly for the rest of its life. That is a quiet advantage that only shows up when something goes wrong.
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.
On a Twin Versus a Four
A large twin with widely spaced firing pulses shows lean fuelling more obviously than a smooth four does. Owners of vee twins and parallel twins tend to notice more.
