Isn't one of the fundamentals of a diesel engine that AFR varies with load, 
while a gasoline engine is designed to operate at constant AFR (excepting 
certain points of enrichment or leaning)? There is no throttle plate 
limiting air flow on a diesel.

IIRC, oxygen sensors are designed to accomodate the constant AFR assumption. 
Even if you could get a wideband to work, you wouldn't be able to tell if 
the engine were running relatively rich or lean.
