DescriptionThe whole story▼
The JP MJ 003 is the preset version of JetPrime's fuel module for the California Touring, with nothing to program and nothing to configure after it is plugged in.
Key Features
- Moto Guzzi California Touring (2012–2017)
- Preset fuel module, no programming required
- Corrects the mixture without remapping the original electronics
- Plug-and-play with model-specific wiring
- Around 200 g, fitted in an evening
- Unplugs at any time, nothing is written to the motorcycle
The Big Guzzi
A 1380 cc transverse twin in a full touring chassis. It is the largest engine Mandello has ever built and it feels every bit of it.
Fully Reversible
Unplug the module, reconnect the original connectors and the motorcycle is standard again in the time it takes to lift the seat. Nothing is cut, nothing is soldered and no software has to be reinstalled anywhere.
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.
Selling the Motorcycle
The module comes off in minutes and goes with the bike or stays with the owner. Either way the machine on offer is a standard one, which suits most buyers.
Nothing Upstream Notices
The engine controller issues its instruction and the module modifies it afterwards. From the controller's point of view the motorcycle behaves exactly as it always has, which is why nothing is logged.
Honest Diagnostics
A motorcycle whose controller has never been written to reports faults properly for the rest of its life. That is a quiet advantage that only shows up when something goes wrong.
The Airbox Lid
Owners sometimes drill or remove it hoping for the same result. That changes airflow without changing fuel and generally makes the mixture problem worse rather than better.
After a Service
Nothing about the module needs resetting when the motorcycle is serviced. Filters, plugs and oil changes have no interaction with it whatsoever.
