I got advice from a dude that works for NGK(NTK?) :
Using heated 02 sensor in place of non-heated 02 sensor? - SaturnFans Forums
Start reading from post #23 and you'll hear what he has to say. His handle is "NGKTECH". He has run my setup for a couple of years without problems, and others have done the same. That *doesn't* document miles, but he appears to come from the harsher climate of Michigan.
Like I said, I'll take the hit if it doesn't last too long.

Awesome, thanks for the link
I just installed a potentiometer in parallel with my coolant temp sensor, with the goal of reduced cold startup enrichment. It works great, except that the idle bounces pretty hard when it first goes into closed-loop, so I'm thinking my single-wire unheated O2 sensor isn't warming up quickly enough.
I just ordered a heated O2 sensor, can't wait to get this in the car and see what happens. Fighting the winter blues...
