….and the result is “remarkable” The slight jerking (which I always had with a warm engine) has now disappeared, the engine takes on the gas much better in the partial load range and pulls up much cleaner than with Lamda control. Ergo seems to be my Lambda very sluggish by now. Should some of you try it out, and see how your boxes behave with the Lambda plugged off. Mine drives much better again. Soon a new Lambda will add to my diet. Not the world. Greetings
