DescriptionThe whole story▼
The JP MJ 008 gives the FZ8 a fuel curve tailored to that engine rather than to every market the model was ever sold into.

- 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 Detuned R1
Yamaha took the older four, reduced the capacity and mapped it for the road. The FZ8 is more capable than its reputation ever allowed.
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.
Altitude and Air Temperature
The standard controller already compensates using its own sensors, and the module's correction is applied on top of whatever it decides. Riding somewhere high or hot does not require anything to be changed.
Two Hundred Grams and a Cable
That is the entire physical product. The engineering is in the curve and in the harness, neither of which is visible when the seat is off.
Who Should Not Buy One
An owner with a standard exhaust, a recent motorcycle and no complaint about how it runs. There is no reason to fit a correction to something that is already correct.
Why Any of This Is Necessary
Emissions regulation has tightened faster than engines have changed, and manufacturers meet it partly by running lean where the test looks. The consequence is felt by the rider rather than measured by the laboratory.
The Cable Tie Matters
A harness left loose eventually finds a moving part or a hot one. Thirty seconds securing it properly is the difference between a component that lasts a decade and one that fails in a wet autumn.
A Note for Workshops
The module is visible under the seat and unplugs in seconds. Any diagnosis on the motorcycle should begin by removing it, which takes less time than reading this paragraph.
