Low-cost, complete wideband O2 Controller suitable as additional SM3-black ECU second lambda controller or universal stand-alone applications.

Its a direct copy of our SM3 integrated wideband controller, wich has proven stability and accuracy.

The screen only shows values in Lambda, for the simple reason Lambda is independent of fuel type.


For easy integration we'll share the layout so the controllers can be integrated in to own projects...
And a printable file with wildly available GoPro Mounting/Car vent support. (see downloads)
