DescriptionThe whole story▼
The JP MJ 007 addresses the 790 Duke's hesitation off a closed throttle, which is the transition every injection system finds hardest and every rider notices.

The Scalpel
KTM's own name for it, and it earned it. The 799 cc twin is light, narrow and demands a precise hand at small throttle openings.
What a Power Module Actually Does
It sits between the motorcycle's loom and its injectors, reading what the standard controller decides and adjusting the injector opening time before the signal arrives. The original electronics keep their job and their diagnostics; the module only corrects the quantity of fuel that reaches the cylinder.
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.
A Component, Not a Project
Some tuning parts start a conversation that lasts a season. This one is fitted on a Sunday afternoon and then never thought about again, which for most owners is exactly the point.
Approval and Local Rules
Fuelling forms part of the emissions approval in most European markets. Changing it moves the motorcycle outside its approved state, which is worth understanding rather than discovering.
The Connectors Do the Work
A harness with the correct plugs moulded on is what makes this a twenty-minute job rather than an afternoon with a soldering iron and a wiring diagram.
Fuel Quality
A tank of poor petrol affects a motorcycle with a module exactly as it affects one without. The correction is a fixed curve and it has no way of knowing what has been put in the tank.
Why Response Is Not Power
Two motorcycles with identical peak figures can feel completely different because of what happens in the first fraction of throttle travel. That difference is worth more on a road than ten horsepower at the top.
