They are operated by the MS2/MS3 processor and ground operated.

  • Passive coils(dumb coils) can be directly connected, good grounds are required!
  • Smart coils(dis coils) can also be operated by the KdFi,however additional hardware or board mods are necessary depending on user requirements.
  • SM3+ ECU's dont require modifications or additional hardware, they can run 6 passive OR 6 smart coils out of the box

-Option 1: board adjustments IGBT removal and bridging IGBT pads (gate to source) 

-Option 2: additional pull-up board available in 2 versions.


These boards are a direct fit on the original basis KdFi boards an very easy to use and instal.
