Electronics International MVP-50.  I have one in the Epic LT.  Robust
and reliable.  Very easy to change parameters for limits and program in
general.  Easy to grab all the engine data with a USB memory stick.  It
has annunciators that diplay when anything is out of limits.  I believe
that I could eliminate the Lancair's or the Epic's annunciator panel
completely and rely  on the MVP-50. =20

They were terrific help in setting up the instrument initially and with
the follow-up.  I had a transducer fail and they sent me a new one
immediately, not waiting for the failed one to be returned. They respond
to phone and email.

Vision Microsystems 1000.  I have a VM1000 in the Lancair IVP.  Not
quite as reliable and have had to run 3 wires drilled through the
firewall and not try to replace the ones through the firewall connector.
The fuel pressure transducer intermittently shows 0 fuel pressure.  I
have had to retighten the transducer connections into the CPU on several
occasions and tighten the connects on the transducer. This has "cured"
the problem for quite a while and then it returns.  The ammeter sensor
failed and was replaced.  An EGT probe failed.

Tech support is very responsive, when you finally get through on the
phone.  Always knowledgeable, courteous and helpful. =20

My VM1000 does not have engine data logging.  I wish that it did.  The
new ones do now log.  Mine is not upgradeable. In doing the GAMI lean
test, the temperature steps are too large to be really accurate.  In
spite of that, I do have a smooth running engine 70 degrees lean of
peak.=20
