Greetings,
I haven't had a
chance to do anything else with my O2 testing, but I've had an odd
thought.
The full story, is
that I originally had erratic O2 readings with the rev-2 configuration.
Primarily, this was staying on the mid, to low end of the scale, but would then
just go away completely, as if it was way too lean. I had used the
same sensor I used before, but now had the EM-2, rather than my old mixture
gauge. It didn't take long before I noticed that the O2 sensor was falling
apart, so it was replaced with the Bosch 11027 sensor that several of you are
using. On the next run, the EM-2 read almost full scale, and I
couldn't do much to change it with the mixture knob. I could hear the
engine getting richer and leaner, but the reading stayed near full scale.
The only time it would change was when I leaned so much that the engine was
starting to cut out, then it would plunge to
nearly zero.
I'll be testing the
reading with my old mixture gauge very shortly, so we'll see what that shows,
but by all rights, the EM-2 should be giving me a valid reading. If
we assume it's correct, then I'm running so rich, that the O2 reading is maxed
through the whole usable mixture range required to
run.
Here's the wild
question- Is it possible that
the fuel is not atomizing completely due to the 30" distance from my
injectors to the engine, and some of it is making it through the engine as
"droplets". It's hard for me to believe that could really happen,
but it would explain the overly rich O2
reading.
Thanks,
Rusty (shouldn't ask
questions so early)
