EGT problem:
I have difficulties with EGT which shows 307/308C constantly no matter what I'm doing. First channel was populated already, second is empty. I only soldered the sensor wire and filter cap.
Input voltage and AD597 output seems OK, even MCP3208 input seems fine (0.1V at room temp), still I get 307C for both EGT channels.
Tried with different firmwares too.
Any ideas?
