John,
I know
that the injectors are staged, i.e. it runs on one set below a certain RPM or
MAP point (forget which) and then kicks in the other set above that. 3000
RPMs seems to ring a bell, but I could be wrong. I thought that it ran on
the primary then added the secondary, but maybe it is the other way
around.
Have
you checked your fuel pressure ? I've had problems with mine running rich
at low RPM's If your regulator is MAP reference, it should only be running 25-30
lbs at idle. Static is suppose to be 34-36 I believe. I have mine
set a little lower, at least on my gauge, because I think that it reads
low. You might want to try lowering your regular and see if it helps
any.

OK,
Guys. Here's another chance for your valued remote diagnosis
input.
After 2 months hiatus my engine now starts reliably and runs
consistently....just very very badly. In all the time
I've had the engine running, with various problems of mixture and
tuning it has NEVER run this rough. It shakes, and max rpm is about 2100.
Each plug seems to have a good spark but today I installed new plugs anyway
and checked the voltage on all coils and injectors. It runs exactly the same
as it did yesterday. The plugs are black and the engine blows a bit of blue
smoke.
It
IS running rich, so I tried changing the overall range with mode 3. As I
lowered the mixture with 7 or 8 pushes the rpm came up a bit, then started to
slow down again. At the best rpm the EC2 is showing slightly higher than
center on the mixture. I tried switching off either set of coils and felt a
degradation with either off. Disabling secondary injectors killed the
engine. Primaries didn't make much difference. I checked compression. 105# on
each rotor.
My
next thought is to check that cold start is operating properly, but I'm pretty
sure it is because the engine slowed down when I tried switching it on.
I spoke with Tracy and he suspects fuel, possibly a bad
connection in the injector wiring, so tomorrow I'll rewire the entire injector
circuit if necessary.
I'm so glad Rusty still doesn't have power. I'm not in
any mood for jokes :(
Thoughts
anyone???
