Description
The SX1 PRO 4T is a fully customizable ECU designed for 4-stroke fuel-injected engines (2023+). It includes a TPS reset cable and delivers the same raw performance as the complete kit version.
What sets this model apart is its simplicity and flexibility:
-
Plug & Play installation: connects directly to the main wiring harness — no electrical modifications required.
-
Full compatibility: supports the latest European and Japanese models.
-
Advanced customization: all calibrations are developed in-house with professional Maya software — the customer doesn’t have to configure anything. D-Spec provides tailored maps ready to install for your specific needs.
-
Performance and value: a more affordable option than the complete kit, while maintaining identical performance.
👉 Ideal for riders who want to maximize their 4T engine’s performance with high-level electronic management, without the extra accessories of the full kit (handlebar controller and Wi-Fi module).
