Alex, I have a note about the sensor but I’m unable to verify if its correct. It may be a digi-key BC2312-ND. Again this is unverified. My notes also indicated the B-Controller uses a fix resistor value of 2.7K ohms. This sensor is listed at 77F – 2.7K ohms. https://www.digikey.com/product-detail/en/vishay-bc-components/NTCLE100E3272HB0/BC2312-ND/769422 Please let the group know what you find out. Good luck, Bobby From: Rotary motors in aircraft [mailto:flyrotary@lancaironline.net]

Subject: [FlyRotary] Re: EC2 temperature sensor My EM3 has a 3 wire temperature sensor, power, ground and signal. From what I see the EC2 only has a 2 wire sender, and a note that you can connect either wire to the EC2 so that means its a resistive sensor. The curve is not linear with a resistive senders from different manufacturers so if I dont use the same one Tracy used, for the temperature curve he programmed into the EC2 for it, the temperature values will be off and subsequently the engine tuning also off, so I dunno but I dont think I can substitute the EM3 temperature sensor either ooops, I just noticed you're looking for the EC2 probe, That number is for the EM2. I just looked through all the info I have on the EC2 and there is no part # for the EC2 temp sensor, but I do recall that it was a different form factor than the LM34. I'd be interested to know, as that is something that would be good to have a spare. Anyone know what the part number is for the temperature sensor for the EC2? I damaged mine modifying my intake manifold and I emailed Tracy but he appears to be out of contact at the moment, thanks in advance,
