Tracy,

To refresh your memory, I recently installed the solid state staging relay
on my 20B Lancair ES.  When doing the install, I didn't reinstall the diode
(to ground).  During a short test flight after installing the solid state
relay, the map table got corrupted.  I wrote for your advice and you
instructed me to connect the diode.  I reinstalled the diode to the staging
relay and went for a short 30 minute flight today.  The "A" map table again
got corrupted.  Switching to the "B" controller resulted in a smooth running
engine.  After landing, I entered the EM-2 tracking mode and it was obvious
that the "A" map table was again corrupted.   I have not reloaded the
default map, in case you would like to take a picture of the EM-2 display of
the map table.

These are the only two instances of this happening that I can recall, both
cases happened after I installed the solid state injector staging relay.
Could the relay possibly be related?

Also, I understand that others with composite a/c have had problems similar
to this (sporatic corruption of the MAP table).  Have you been able to
determine a common cause?  Any suggestions?

I am posting this to the fly rotary group in hopes that someone on the list
may have already "been there, done that".

Thanks,
Mark S.
