Hi Tommy,

    Only difference as far as I know is that the one wire sensor takes a
while to warm up and give a correct reading - which probably makes it
unsuited for most of todays automobile CPUs.  .  But for aircraft usage,
that should pose no problem as once you get started it will be warmed up
quickly by the rotary horridly hot exhaust.
I got started with a 4 wire lead (mainly because that O2 sensor had the
response cruve for different exhaust temps), but I have found that it
doesn't really matter for our uses.
