DescriptionThe whole story▼
The JP CJP 042B puts the R1200GS's fuel map in the owner's hands: revs on one axis, load on the other and a correction in every cell.
Key Features
- BMW R1200GS (2004–2018)
- 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 Air and Water Boxer
BMW's 2013 redesign put water cooling around the exhaust side of the heads and moved the throttle bodies. Fuelling behaviour changed noticeably with it.
The Honest Summary
A programmable fuel controller for an owner who has modified the engine and wants the mixture to match. It rewards effort and it does nothing at all without it.
Firmware
JetPrime issue updates through the same software. They are infrequent and worth applying before starting a long mapping project rather than in the middle of one.
What Is Supplied
The unit, a harness for one motorcycle and access to the software. The wideband, the laptop and the time are the owner's contribution.
Regulations
Championships differ on engine management. Some permit added fuel controllers freely, some restrict them and a few prohibit them, and only the rulebook decides which.
Firmware Updates
Occasional and delivered through the same software. Apply them before starting a long project rather than halfway through one.
Reading the Year Span
Injection hardware changes more often than engines do. The years in the listing are part of the product, because the harness is cut for a specific arrangement.
A Note on Warranty
An additional controller is visible and a dealer will see it. It unplugs in minutes and the motorcycle is standard, which is the whole reason to prefer this over a reflash.
A Map Has No Ceiling
Unlike a fixed curve it can keep improving as long as somebody keeps working on it. That is the argument for the higher price and it is only worth anything to an owner who will do the work.
