I was just thinking, what if you fool the lambda-sensor to give false reading, about 100mV less or something, driving it into bigger than 14.7:1 ratio, and so it would run leaner?
I did search a lot about this, but with mixed disgussion. But since it is'nt not much disgussed, should it belong to Unicorn corral?
But i was thinking, that if you just put a variable resistor in between lambda signal and ground, big enough to not to burn it. Would that be enough? ..Or in series with the signal.
And of course, A/F meter so you see the results.
Any thoughts about this?
