Real vehicle validation
VasfEFI S2 is not only a bench prototype. The platform has been validated on a real Hyundai test vehicle with crank and cam synchronisation, sequential operating mode, CAN communication and live ECU operation through the VasfEFI software ecosystem.
Sequential control
Sequential mode tested on the vehicle platform, with injector and ignition control prepared for real engine operation.
CAN communication
CAN bus operation validated, including dashboard / RealDash-oriented data broadcast support.
Installer-focused hardware
OEM-style 56-pin connector, documented pinout, wiring diagram, filtered sensor supply and separated sensor/power grounds.
Overview
VasfEFI S2 is designed for sequential fuel injection, smart ignition coil control, boost control, idle control, fan control, launch/clutch input, auxiliary outputs, CAN dashboard data 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.

Available configurations
VasfEFI S2 is quoted by configuration, so a bare standalone ECU is not mixed with a kit, a wideband option or a vehicle-specific PnP package.
Standalone ECU
ECU unit for custom projects where the installer builds the harness, selects sensors and performs the complete calibration.
Universal kit
ECU with selected connector, wiring and accessories prepared for a new installation. Wideband and extra modules are specified separately.
Vehicle-specific PnP
Adapter or interface prepared for a confirmed vehicle pinout, with base map preparation and project-specific documentation.
PnP with startup support
Vehicle-specific package with direct support for first start, log review and initial correction before final calibration.

Professional installation required.
VasfEFI S2 must be installed and calibrated by a competent professional familiar with engine management systems, vehicle wiring, ignition systems, fuel injection systems and automotive electrical safety. Incorrect wiring, grounding or calibration may cause ECU damage, engine damage or unsafe operation.
