Engineering philosophy

  • Automotive power integrity: reverse polarity, cranking brownouts, EMC-minded layouts
  • Signal integrity: VR/CKP conditioning, ADC references, grounding strategies
  • Built for real engines, not benches: temperature, vibration, noise, long-term stability
  • No magic: clear interfaces, reproducible results, documented behavior
Professional installation required.
VasfEFI ECUs are not plug-and-play universal products. Wiring, configuration and calibration are required.
