Mattituck installed the plasma II EI on my new IO-320. All test bed figures looked great. Now that the engine is installed and flying i am having an issue. After confirming all parameters of my plasma II installation (verified timing , wiring, troubleshooting all coils, checked plugs, mixture setting, etc) I have still not been able to determine why I get a 120-150 drop in rpm when I run only on my plasma II during a mag check. The slick mag drops @ 90 which is normal, but the EI should be very little, maybe 25rpm. The engine also appears not to be making full power - only 82% on take off WOT. Any ideas? All parties appear to have exhausted ideas. Has anyone had a similar experience??
