    Lambda O2 sensor modification to increase air fuel ratio and run leaner.

    I think the lambda sensor in question is a EGO (at least for my project), ie not heated like a HEGO or UEGO. So I suppose you are right in saying that it'll have very little input in the feedback control loop. Would you recommend MAP sensor manipulation?

    Lambda O2 sensor modification to increase air fuel ratio and run leaner.

    A digram of how the Lambda sensor works; If we presume the engine is reading 0.45V being the stoichiometric value. In order to make the engine run leaner, the ECU needs to be fooled into thinking it's running too rich a higher voltage; a 0.1V increase to 0.55V for example. I'm unsure of the...
