Pistonix Forge

The base ECU. Forged from the ground up for Twin Cam and custom V-twin.

Forge is the entry point of the Pistonix lineup. It runs sequential injection and ignition, internal datalogger, basic boost control and closed-loop AFR with a wideband sensor. The commercial launch focuses on Harley Twin Cam 2004-2016 — the largest installed base in Brazil — and the roadmap covers Sportster (all generations), Evolution Big Twin and Shovelhead in subsequent waves.

Estimated price $900 – $1,160 R$ 4.500 – R$ 5.800

Values may shift up or down before pre-order opens.

Features

What is inside.

01

Sequential injection and ignition

Each cylinder on its own channel; 45° V-twin asymmetric timing handled in firmware.

02

Closed-loop AFR

Real-time correction with wideband. Independent tables per cylinder bank.

03

Boost control

PWM for aftermarket turbo wastegate. 2D tables on RPM and MAP.

04

Internal datalogger

USB CDC stream during a session and full log dump after the run.

05

Robust limp mode

Detects sensor failure and falls back to a conservative map before the engine is hurt.

06

Curated basemaps

Ready-made tunes for Twin Cam stock, slip-on, big-bore and basic turbo. Sportster and Evo arrive in later waves.

Who it is for

Who we built it for.
