Expanded standalone ECU platform
VasfEFI S2
Standalone engine ECU for custom engine management, motorsport projects and advanced vehicle conversions.
Overview
VasfEFI S2 is designed for sequential fuel injection, smart ignition coil control, boost control, idle control, fan control, launch/clutch input, auxiliary outputs and external sensor integration.
The ECU uses an OEM-style 56-pin connector and separates sensor grounds, power grounds and filtered 5 V sensor supply rails for cleaner installation practice.
