Which ECU for which engine.
Each V-twin platform has its own quirks — sensor pattern, trigger wheel, ride-by-wire, HDLAN. Here is the map of which Pistonix ECU fits each one.
Harley Twin Cam
Largest installed base in Brazil. Flashed Delphi ECMs are the norm; Pistonix Forge is the direct path off them.
Commercial pilotHarley Sportster
Same Delphi platform as post-2004 Twin Cam. Cheap and simple way to learn V-twin tuning.
Wave 2 — post-launchMilwaukee-Eight
Modern platform with ride-by-wire and HDLAN. Pistonix Apex is the only model with throttle PID and HDLAN passthrough.
Wave 3 — dedicated ECUCustom V-twin
Custom block — S&S/RevTech/Ultima — without the Harley ECM. Maximum tuning freedom and no fight with the OEM brain.
Wave 2 — post-launchHarley Evolution Big Twin
Big Twin Evo is a future wave. Pistonix Forge gains a retrofit mode for carb-to-EFI conversions and standalone ignition.
RoadmapHarley Shovelhead
The carbureted classic. Pistonix enters as standalone programmable ignition, with optional EFI later.
