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.
