DescriptionThe whole story

The JP MJ 001 improves the Tuareg 660's throttle response and smoothness, which is the manufacturer's claim in full and a considerably more honest one than most.

Key Features

  • Aprilia Tuareg 660 (2021–2026)
  • 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

Tuned for Traction

Aprilia softened the 660 twin's delivery for the Tuareg because a loose surface asks for metering rather than urgency. The hardware is otherwise the same as the sports bikes.

And With an Open Filter

More air on the intake side has the same effect from the other direction. The standard closed-loop correction handles part of it and runs out of authority for the rest, particularly at larger throttle openings.

It Does Not Touch Ignition

Advance and retard are the standard controller's business. A fuel module cannot alter them, which limits what it can achieve and also removes the commonest way to damage an engine electronically.

Lambda Control Is Not Bypassed

The module works with the oxygen sensor loop rather than around it. Nothing is disconnected, spoofed or hidden, which is one reason the fault memory stays clean.

Oxygen Sensor Interaction

Nothing is disconnected and nothing is simulated. The standard trim loop continues to operate in the band where it operates, and the module's correction sits on top of the result.

Intake Changes Too

A high-flow filter shifts things the same way. Owners running both an exhaust and a filter are the furthest from the factory calibration and have the most to gain.

Track Days

On a circuit the throttle is either shut or open and the transition matters less than it does on a road. Riders who only ride circuits will notice this module least.

Big Singles

A thumper is the clearest case of all. With one cylinder and one firing event every other revolution, any hesitation at small openings is felt directly through the chassis.
