SLC Free - V2.01


I’ve build SLC Free V2.01 from github.

I have lot’s of problems with start the SLC, after putting LSU 4.9 in the exhaust lambda is all the time 1.36 (maximum is 1.36). What should I do ?

Connection fine, I’ve tried some different firmware and still the same.

Please help me :slight_smile:

Test with a lighter shows that lambda is changing, but not in that way I want. Idk why it’s not chaning in the car exhaust.


I did not design that board.

My guess is that either the sensor is a clone sensor or you did not connect all 6 terminals from the sensor connector to the wideband controller.
