Hi David. Tracy created a Closed Loop version of the code for the EC2, which he provided to me some years back. I have an EC2 and EM3 but I am not using the EM3’s autotune function which was Mode #9, rather the EC2’s own Closed Loop function in Mode#1&3 in common with the latest EC3 code.

Be sure to verify that your wideband sensor outputs in the range of 0 - +5 volts if using a wideband type.
