Nexus S2 ECU Only

The Heart of the Next-Gen Electrical System

The Nexus S2 VCU (Vehicle Control Unit) is a technological leap forward, integrating the functions of an Engine Control Unit (ECU), Power Distribution Module (PDM), Wideband Controller, and Data Logger into a single, robust device. This is the unit only, ideal for replacing a damaged unit or for installations where the harness and connectors are already prepared.

Intelligent Control

Designed for 4-cylinder and 2-rotor applications, the Nexus S2 offers 4 high-current (25A) PWM-capable outputs for powering fuel pumps and fans, alongside dedicated engine control drivers. It features 128MB of internal logging, an onboard wideband controller (sensor required), and the powerful NSP software suite for intuitive calibration. Its PDM functionality simplifies vehicle wiring and improves reliability by removing mechanical relays.
