This may occur because in one fraction of
a second you are opearting at WOT (lots of fuel flow) and the
next down to idle.
In thinking about
this some more, it would make sense that I didn't have nearly the same problem
before. In the rev-1 version, I had the primary injectors in the block,
and the secondaries were only about 14 inches away. Now, all four
injectors are about 30 inches away, so there's a lot more fuel left in the
intake when you chop the throttle.
I agree with
Tracy that this isn't my normal operating mode, but when testing the engine, I
like to try everything I can think of, so there won't be any unpleasant
surprised in flight. FWIW, the turbo used to throw a nice flame
out the short pipe when I'd chop the throttle, but I don't know if that
would make it to the end of a longer pipe, through a
muffler.

test my O2 reading on the
EM-2)
