Steve -
It's interesting to see the differences. On my '87 digifant system, the
temp 2 drops to as low as .08 when very warm, but generally seems to run
about .10 to .14. The Temp1 and Temp2 readings with a cold engine depend on
outside temperature, but should be almost identical.
The O2 starts at about .35 when cold. After it warms up, it hardly ever
goes to negative, but gets as high as .6 or .7. It bounces constantly. I
think you can sort of tell how hard the engine is working. When I
accelerate the values seem to stay high for awhile. When I am coasting, the
values drop to very low figures.
I would be curious to know what other people have for a warm idle AFM
reading. Mine is about 1.5, after fiddling with the spring in the AFM.
When cold, it's about 1.8 at idle.
Also, what are you getting for Voltage? Mine runs at about 13.1 most of the
time, dropping below 13 when I run the headlights, or the AC compressor is
on. (It cycles above and below 13 as the compressor clutch engages and
disengages).

Steve,
Temp 1 and temp 2 start at same value. Temp 2 slowly drops to .24v,
fully warmed. O2 signal starts at .33v, slowly climbs to .65v as motor
warms. When temp 2 reaches about .35v, O2 signal swings from -.14 to
.63v. I've never seen it hover around .50v. Are my readings normal? Who
knows! It runs strong however.
