Will be interesting to see what your test = reveals. Jeff From: Bobby J. Hughes Subject: Re: [FlyRotary] Re: F/A and EGT data Date: Sun, 14 May 2017 12:46:00 -0400 To: Rotary motors in aircraft Message Header Yesterday I remembered my rotor 1 primary injector has a connection to the = EC3 for fuel flow and AFS engine monitor for RPM. I believe I place a 2k re= sistor between the injector and AFS and possibly the EC3. This may be affec= ting the pulse on / off time when manually changing the mixture. I'll test = by disabling the primary injectors at a stable rpm, manifold pressure and F= /A while observing EGT's.
