DescriptionThe whole story

The JP MJ 004 is what an owner fits to the Tiger Sport 660 after an exhaust, when the standard closed-loop correction has run out of authority.

Key Features

  • Triumph Tiger Sport 660 (2022–2024)
  • 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

A Sports Tourer for the Money

Triumph put the 660 triple into half-faired bodywork with a comfortable seat. It covers ground quietly and costs remarkably little.

Diagnostics Still Work

Because nothing is written to the original controller, the service history stays readable and any fault the motorcycle develops is reported normally. A masked fault memory is one of the real costs of the alternatives.

What a Dyno Would Show

Very little at peak. The differences a fuel module makes are at part throttle and in transition, which is precisely the part of the map a full-throttle power run never visits.

No Adjustment, By Design

Some owners want a dial to turn. This module deliberately does not have one, because a curve worked out for the engine is more reliable than one worked out on a road by somebody guessing.

Warm-Up Belongs Elsewhere

The enrichment a cold engine needs comes from the standard controller reading its own temperature sensor. A module does not participate in that and cannot improve it.

No Procedure Afterwards

Nothing to pair, calibrate or reset. The engine is started and the correction is already in place, which is unusual enough among electronic parts to be worth stating.

The Engine Is Not at Risk

The correction is small, it is applied in the rich direction where it matters and the standard controller's protections all remain active. This is not a device that can lean an engine out.

The Cost of Doing Nothing

A motorcycle with an aftermarket exhaust and a standard map is not damaged, only running further from ideal than it needs to. Plenty of owners live with that quite happily for years.
