SCS Delta 400S ECU

The SCS Delta 400S ECU is our smallest unit, but it is also the fastest and most powerful in its class. Packed with features, lightweight, and exceptional value — it truly delivers a punch.

With adaptable hardware configuration, CAN bus integration, and advanced control functions such as variable valve timing, closed-loop boost and fuel control, coil-on-plug ignition, and up to 6 fuel injector outputs, the Delta 400S offers outstanding flexibility. All configuration and calibration are handled through our SXTune software.

Fuel calculations can be based on volumetric efficiency, pulse width, TPS, MAP, or a combination of these strategies.
