You'll need a DAC or the ghetto-DAC (PWM+Resistor+DAC) to get a sine-wave off and arduino if I understand correctly.
I'm really interested in having the same thing. As now I want to achieve something similar as well. I know that wideband-o2 sensor -> narrowband-o2-sensors convertors can be bought off-the-shelf for hundreds of dollars but where's the fun in that.
Nice work.

Well, the way I'm thinking about it, you would have to use one of the after market wide-band controllers as the input for the arduino anyway. Unless of Of course you have the arduino controlling that as well. Which may not be that difficult, however getting the heating cycle down Would-be difficult ...The Bosh LCU 4.2 and LCU 4.9 are very long life sensors but improper heating can be very detrimental to the life expectancy.
My wideband controler/gauge/sensor cost 219$ It is expensive. But not a whole lot more than just an 02 sensor .
