DescriptionThe whole story▼
The JP MJ 004 is what an owner fits to the S1000RR after an exhaust, when the standard closed-loop correction has run out of authority.

- Plug-and-play with model-specific wiring

Four Cylinders, One Map
BMW's superbike has always been mapped conservatively in the lower riding modes and aggressively in the upper ones. What the engine does for a given opening depends heavily on which mode is selected.
On a Machine Being Sold
Unplugging the module and putting it in a box makes the motorcycle standard again. Whether that helps or hurts the sale depends entirely on the buyer, which is an argument for keeping the original connectors in good condition.
Weight and Space
Two hundred grams and a body about the size of a matchbox. On most motorcycles the harder part is finding somewhere tidy for the cable rather than for the module.
Against Flashing the Controller
A full remap can do considerably more and is considerably harder to undo. This module is the narrower, cheaper and entirely reversible option, and for a great many owners that is the right trade.
Dealers and Terms
It unplugs in minutes. Owners inside a warranty period generally remove it before an appointment and refit it afterwards, and the connectors are designed to tolerate that repeatedly.
Nothing at the Pump
Fuel consumption stays where it was within any margin anybody can measure on a road. Claims in either direction should be treated with suspicion.
Reading the Listing Before Ordering
The year span in the title is part of the product. Manufacturers change injector connectors and harness routing mid-generation, and a module cut for one span will not simply plug into the other.
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.
