pjvr99 Posted June 13, 2010 Share Posted June 13, 2010 Hey HerkyWorld Got an unusual situation here. Engine starts normal, LSGI torque set correctly. When the LSGI button is pulled to upshift to Normal Ground Idle, torque stabilizes for a moment at +-1200"lb ........ then increases to +-6000"lb, rpm decays to 94%, and TIT increases. Also prop noise indicates the engine is labouring. When LSGI button is pushed in, everything returns to normal. Standing on the blade line, you can see the pitch change occurring. Changed out valve housing, pitchlock regulator, and low pitch stop. Also removed all cannon plugs to remove electronic influence - no good! Stays the same ..... Anyone out there seen this before? any ideas, theories ........ anything? Have a great day PJ Quote Link to comment Share on other sites More sharing options...
