John, if I'm not
mistaken, didn't you add the EM-2 while waiting for the new turbo? In
other words, this is the first time you've really run the engine hard since
having the EM-2?
Correct
Since your temps
are much higher than before, I would submit that it's likely that either you're
previous temp readings were wrong, or your current ones are, particularly in
regard to "negative" oil pressures. I think you need to be very sure
you're EM-2 is calibrated, and not by just matching one number to a gauge.
Check a low, mid, and high level to make sure the EM-2 is correctly
calibrated.
Agreed. I wish I knew an
easy way to do that.
Also, didn't you fall for the old Mazda
practical joke of using the rear housing water temp sensor for oil temp?
Was that just changed while waiting for the new turbo? If so, all bets are
off as to what he temp used to be.
Correct again. But, the
coolant AND oil temps are both rising much more than they were before, and
the ambient temp is 20 degrees cooler. Perhaps the old gauges were off, but
before installing the EM2 I did run WOT for 1.5 hrs without apparently
overheating anything or loosing any coolant, so I think they were
ok. Also, this seems to coincide with
strange engine / mixture behavior. Note that I had to richen the mixture
almost to the stop to keep it running, and that I turned off one set of
injectors to get it to smooth out. Could this be related somehow? How many
annoying failures can one guy have at a
time???
