It sounds (reads) like the wide range  O2 meter is doable and not to 
expensive ($300 or so).
Do you have any idea about the benefits over the original el cheapo 
O2 analyzer?  If I got my old (less than 30,000 mile) single lead 
sensor running at about 750 deg.F. after warm up and have the exhaust 
system bonded to electrical ground, how much will I benefit by going 
to a three lead system (I don't think much), or to the wide range O2?
