If he has not upgraded it, the instructions you have would be the valid ones even if they are old. My EC2/EM2 were updated in Nov07. The one wire O2 sensor(Tracy suggests the NAPA OS700 with the body of the sensor grounded) connects to the P2-8 pin on the EM2 and does not connect to the EC2. Hope some of this helps. Bill B -----Original Message----- From: Rotary motors in aircraft [mailto:flyrotary@lancaironline.net] On Behalf Of Stephen Izett Sent: Sunday, November 24, 2013 5:19 AM To: Rotary motors in aircraft Subject: [FlyRotary] EC2 & EM3 Hi guys I'm doing finishing wiring of my EC2 / EM3 setup. My documentation is quite old and I'm wondering if anyone has more recent derivatives of Tracy's documentation. I'm particularly interested in Tracy's latter code that I understand included a closed loop fueling scenario. As I understand closed loop, he would need an input from an O2 sensor. Is this information coming from the EM3's O2 input or is the EC2 reading an O2 sensor directly itself? Thanks very much.
