 Patrick,
 
 I installed an Electronics International MVP-50 in my Lancair IV-P and
consider it one of the most useful and reliable pieces of equipment in the
airplane. I can recommend it without reservation.
 
 I am not familiar with other systems but understand there are some good ones
available. I would change out the sensors if you install a new system. Eight
years is a good service life for these things, and you'll significantly reduce
your installation and calibration time if you use the sensors recommended with
the display unit you purchase.
 
 My two cents. Picture attached.

 Subject: [LML] Question regarding EMS (JPI, Dynon...)
 
 Hello to all,
 
 My engine monitoring system is a Vision Microsystems (VM) EPI 800 and worked
 well for the last eight years - and still works fine.
 
 I'm thinking of a replacement system - in case of a major failure of the
actual system.
 
 My recent research showed that most of the installed sensors are compatible
with the
 EMS used today.
 
Fuelprobe compatibility?
 Does anybody knows about the compatibility of the VM Fuel probes? I have two
of them
 installed in the wings. A calibration was done back in 2002 to respect of the
Fueltank geometry...
 
 Which system to for?
 What are y<our experiences with JPI, Dynon and others?
 
 Any hints and thoughts are welcome, thank you.
