O2 sensor fooler

[Seth Allen]

Just got off the phone with another student here at WWU and he reverse 
engineered last years o2 sensor fooler (we lost the original schematic). 
Basically, we used it on a CNG car and then on a propane powered van, the 
idea to get the engine to run at lambda =1 for each respective gaseous 
fuel.  The device simlply reads the input voltage from the o2 sensor and 
adjusts it.  I think the offset in voltage is adjustable, I am not sure.  
If this sounds like an interesting post to a web page or as an e-mailing, 
tell me.  It should work fine as to make a gasoline car run rich, like 
12:1 air fuel gravimetric ratio, or so.

So if there is sufficient interest, I will make my friend cough up his 
schematic and notes.
