First things first. I think it is time to get the instrumentation 
working properly.  Since I have some idea of what to do.  Since RPM is 
dropping out above 6000 RPM,  and RPM is reading 0 when running only the 
Pri or Sec injectors, and MP is very erratic at best.  My best guess is 
that it is electrical, NOISE??  I'll follow Tracy's suggestion and run 
an additional buss from the battery to power just the EC-2 and the 
EM-2.  I'll keep it away from  the fuel pump switches and lines, the  
coil disable switch, the injector disable switches etc.  Now that I 
think about it, the EC-2 controller is right next to all these things.  
It will be easy to pull it out of the panel and run the engine with it 
in my lap.  I'll try that first and then the rewire.  I'll keep you all 
posted as to the result one way or the other.  To all who sent 
suggestions, I'm working on detailed responses  in the next day or so.
Thanks,

Don Walker
