Hi
Al, I thought those comments were interesting so I am sending them to the
list.
Thanks, I got the O2 sensor back. I don't know
what PN it is, it is the one that Tracy sells with his O2 sensor. I tried
to install it yesterday but discovered that the bung and plug are now
rusted/welded together - there was no getting the plug out. Will have to
wait for the new exhaust system for the new turbo.
I am
also back to having rough idle issues since removing the turbo. Just those
slight differences in the MAP seem to have made a big change. Also -
losing all that fuel out my intake may have caused a change.
Yesterday I re-installed the plenum over the
intake.
I did
think of one additional possible solution. Each of the barrels on the TWM
has a small air inlet with a pin. I have these closed all the way because
I thought it might help with the idle. However, I now wonder if maybe that
air inlet is for the purpose of atomizing the fuel.... Does anyone
know? Maybe I will try to open them up a little.
As far
as Fuel in the MAP line - mine are solid so I wouldn't know. It is
something to keep in mind. I don't think it should adversely affect the
pressure readings, however.

Hi;
Dave,
I presume you got
the O2 sensor OK.
BTW; what model O2
sensor is that? The Bosch 11027 that I bought is quite different
looking.
Sorry to hear about
the strange issue of fuel coming out of the TB barrels. I guess that
goes away when you get the air plenum back on with the turbo. I have a
strange issue with fuel collecting in a low spot in the MAP sensor line.
I would not have known had I not added a swag of some larger diameter clear
tubing to add volume just before the EC2 on the cabin side. It is
strange that at the connection just below the manifold, which is also a low
spot, there is no fuel. In probably about 20 minutes of running enough
fuel collected to close off the 5/16” i.d. tubing at the bottom of the loop.
Don’t know how it is getting there, or what to do about it. Have you
ever noticed fuel in the MAP sensor line?
I’m still having
problem of the staging not working, and very poor operation at low MAP with
the primary injectors on. It runs great with secondary only at low MAP;
and both sets on at speeds above about 2500 rpm. Tracy now suggests
sending the EC2 back to him for checking out.
Best,
Al
