DescriptionThe whole story▼
The JP CJP 084H is for an owner who has already fitted an exhaust to the R1 and now wants the mixture measured rather than assumed.
Key Features
- Yamaha R1 (2007–2025)
- 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
The Crossplane Crankshaft
Yamaha borrowed the firing order from their MotoGP machine, which removes the inertial torque spikes an inline four normally produces and changes how the engine picks up.
Or Pay Somebody
A tuner with a dyno will develop a map on this unit in a few hours. That costs money and produces a better result than most owners manage alone.
Two Owners, One Bike
The map lives in the unit, not in the rider. Anybody who rides the motorcycle gets whatever was last written, which is worth remembering on a shared machine.
Bought Properly
With a measured mixture and methodical sessions it produces a motorcycle that fuels correctly everywhere, which is something no preset curve can promise.
Cell Blending
A correction in one cell affects its neighbours through interpolation. Maps that look smooth on screen feel smooth on the road, and jagged ones announce themselves immediately.
Or Book a Dyno
Several hours with somebody who has mapped that engine before produces a better result than most owners reach alone, and the unit is the same either way.
Support
JetPrime answer questions about their own software. Between that and the number of owners running these units, very little is genuinely uncharted.
A Full System Versus a Slip-On
A complete exhaust changes the gas flow far more than a silencer alone. The mapping effort scales with it and so does what a good map is worth.
Documentation of the Configuration
Which exhaust, which filter, which fuel and which map file. That record is what makes a map reusable next season and what makes it worthless without.
