For those of us who look forward to technology advances, Aerosance has just completed their testing for certification of the FADEC  TSIOF550E system.  Coupla changes, both simple and yet novel, seem to have made it work.  The restrictor plate on the throttle body has been modified with a few holes.  This changed the turbulent airflow at ultra low power settings and yields a smooth idle.  And the circulating fuel flow through the engine is now greater, keeping the system cool and eliminating vapour surging. 


It's been a long time coming.  It will be good to have this new offering among the options.  I hope to have it on my ES-P early in the New Year.
