DescriptionThe whole story▼
The JP CJP 042B is the more capable and more demanding of JetPrime's two fuel units for the Mana 850 GT, and it does nothing at all without a wideband and some patience.
Key Features
- Aprilia Mana 850 GT (2009–2016)
- 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
A Motorcycle With No Gears
Aprilia gave the Mana a continuously variable transmission, which means the engine sits at whatever speed the electronics choose rather than where the rider put it.
Model-Specific Wiring
The harness is cut for one motorcycle with the correct connectors moulded on. That is why the catalogue lists machines rather than engine families and why year spans matter.
Not for a Standard Motorcycle
An unmodified machine with the original exhaust does not need a programmable map. The cheaper preset module addresses that case and this one is overkill for it.
Race Fuel
A different octane rating and a different energy content change what the engine wants. Anybody switching between fuels needs two maps and the discipline to write the right one.
Safety Margin
Map slightly rich where the engine works hardest. The power difference is negligible and the consequence of being wrong in the other direction is not.
The Original Controller Is Untouched
No parameter written, no adaptation cleared, no fault memory disturbed. Every diagnosis on the motorcycle afterwards reads the factory's electronics.
Logging Software
A wideband with a logging output turns a road ride into data. Analysing it afterwards is safer and more productive than reading a display at speed.
A Second Set of Injectors
Not something this unit supports. It manages the standard injectors, and anybody needing more fuel capacity is beyond what a piggyback controller does.
When It Is Finished
When another session produces no change you can measure and none you can feel. Beyond that point the work is a hobby rather than an improvement, which is a perfectly good reason to continue.
