Bosch ADV-sensor support, additional fault registers added and fault indication via the analog output !

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

Our custom wideband sensor heating cycle is continuous monitored, avoiding overheating and destroying sensors!

Due to the perfectly closed-loop temperature control; the Tiny O2 Controller is accurate, responsive and reliable on any application.

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

The optional O-led screen has great visability day or night and makes it very easy to read under any circumstances.
