DescriptionThe whole story▼
The JP CJP 084H puts the YZF-R1 Race's fuel map in the owner's hands: revs on one axis, load on the other and a correction in every cell.
Key Features
- Yamaha YZF-R1 Race (2025)
- Fully programmable fuel map, written on a PC
- Complete two-axis management: engine speed and load
- For engines with an aftermarket exhaust or air filter
- Plug-and-play with model-specific wiring
- Unplugs at any time, nothing is written to the motorcycle
Sold Without Lights
Yamaha now delivers the R1 as a circuit-only machine in most of Europe, with mapping that assumes an exhaust system will follow.
Small Steps
Two or three percent at a time in the cells being worked on. Large jumps produce an engine that surges between operating points and tell the mapper nothing useful.
Altitude and Temperature
The standard controller compensates using its own sensors and this unit applies its map on top. A map developed at sea level still works in the mountains, only less precisely.
A Rich Map Is Not a Safe Map
Excess fuel washes bores and fouls plugs. The target is correct, not generous, and a wideband is what tells the difference between the two.
Plan the USB Access
Nothing is more irritating than removing a seat unit every time the map changes. Route the connection somewhere reachable before securing the harness.
Keeping Notes
Which map, which exhaust, which fuel, which date. Six months later that record is the difference between improving a map and starting again.
The Point of It
An engine that has been changed deserves a mixture that follows the change. This unit is the tool for doing that properly rather than approximately.
Overrun
A closed throttle at speed is a region where small changes are felt as popping or as engine braking character. It is worth mapping deliberately rather than by accident.
What a Session Actually Looks Like
A quiet road or a dyno, a laptop connected, a wideband reading logged, one region of the map adjusted, then the same run repeated to see whether the number moved. Three or four rounds of that fill an evening.
