Lambda O2 sensor modification to increase air fuel ratio and run leaner.
Lambda O2 sensor modification to increase air fuel ratio and run leaner.
(OP)
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 current or resistance of the sensor.
Would a voltage divider circuit be required to increase the voltage? Would this work? Thanks

Would you recommend MAP sensor manipulation?
