DescriptionThe whole story▼
The JP CJP 012D manages injector opening time on the Softail LOW Rider ST Fxlrst across a full two-axis map, programmed on a PC and stored as a file the owner keeps.
Key Features
- Harley Davidson Softail LOW Rider ST Fxlrst (2022–2026)

A Bagger From the Factory
The ST adds a frame-mounted fairing and hard panniers to the Low Rider S. It is Harley building what customisers had been building for years.
The Honest Summary
A programmable fuel controller for an owner who has modified the engine and wants the mixture to match. It rewards effort and it does nothing at all without it.
Reversibility in Practice
The original connectors go back together in minutes and nothing has been written to the motorcycle. That matters at a service, at a sale and during any diagnosis.
A Rich Map Is Not a Safe Map
Excess fuel washes bores and fouls plugs. The target is correct, not generous, and a wideband is what tells the difference between the two.
Reading a Wideband
The display shows the mixture in real time. Holding a steady load and watching the number is the entire technique, and it is considerably duller than it sounds.
The Second Owner
A motorcycle sold with this fitted should come with its map file. Without it the next owner has a programmable unit and a blank sheet.
The Laptop in the Paddock
Somewhere dry, charged and with the cable already attached to the motorcycle. Mapping between sessions is the point of this unit and it needs a working bench.
The Reward for the Effort
An engine that pulls cleanly from anywhere, holds a steady speed without hunting and answers the throttle the same way on every corner exit.
Riding the Empty Map First
Worth insisting on. A motorcycle you have felt with every cell at zero gives you a reference; one you started changing immediately gives you nothing to compare against.
