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=E2=80=99s autotune =
function which was Mode #9, rather the EC2=E2=80=99s own Closed Loop =
function in Mode#1&3  in common with the latest EC3 code.

Cheers

Steve Izett
