Revolutionize your racing performance with the SM3+ V2 Elite ECU standalone unit. Engineered for the rigors of the racetrack, this advanced Engine Control Unit offers cutting-edge features including 8 cil sequential ignition and fuel control for lightning-fast acceleration and precise engine performance. With dual onboard lambda sensors, GPS, and accelerometer integration, along with real-time monitoring and customizable tuning options, the SM3+ Elite ECU standalone unit empowers racers to fine-tune every aspect of their engine's performance for optimal power delivery and throttle response. Dominate the competition and elevate your racing experience with the SM3+ ECU standalone unit.

Our SM3 is smart, it will automatic revert to master USB connection as soon as the USB cable is plugged in! Without USB connection it will switch to Wifi.


It has the same rich features as our SM3+ ecu but with additional:

  • GPS Onboard
  • 3-Axis Digital Accelerometer Onboard
  • Wifi Onboard
  • 2x LSU4.9 Lamba Controllers Onboard
