Thanks Dave. I’m guessing a feature like that adjusts the flash and enables you to dial in what you want and then your just looking for the reference marks to line up. I would imagine that makes it easier instead of having to mark out whatever your reading from. I’d still like to have a definitive process to move forward with from Tracy as the designer.

You are on the right track because retarded timing will raise exhaust temperature. I have a 13b with Tracy's EC2\EM2 and the RD-1AB redrive. >> >> Thanks >> Dave Williams >> >> -----Original Message----- >> From: Rotary motors in aircraft [mailto:flyrotary@lancaironline.net] >> Sent: Wednesday, February 23, 2022 6:45 PM >> To: Rotary motors in aircraft <flyrotary@lancaironline.net> >> Subject: [FlyRotary] Timing >> >> >> Hi friends >> >> On my last flight I experienced high indicated EGT’s so as part of looking into this I would like to check my timing. >> >> I have a Renesis engine and Tracy’s EC2. >> In his A8 (Renesis) version of the handbook under Mode#8 Timing Adjustment it says to refer to ‘Initial Timing Adjustment’, however I can’t find any such instructions in this version, probably because it has a fixed position CAS. >> Can anyone enlighten me on what the static timing should at a given idle rpm? >> >> Much appreciated. >> >> Steve Izett >> >> >> -- >> Homepage: http://www.flyrotary.com/ >> Archive and UnSub: http://mail.lancaironline.net:81/lists/flyrotary/List.html >> >> >> -- >> Homepage: http://www.flyrotary.com/ >> Archive and UnSub: http://mail.lancaironline.net:81/lists/flyrotary/List.html > > > -- > Homepage: http://www.flyrotary.com/ > Archive and UnSub: http://mail.lancaironline.net:81/lists/flyrotary/List.html > > > -- > Homepage: http://www.flyrotary.com/ > Archive and UnSub: http://mail.lancaironline.net:81/lists/flyrotary/List.html
