Follow up to my post about the oxygen sensor problem

My 2001 Subaru Forester has aftermarket catalytic converters. The check engine light kept coming on and the code was always the same indicating the catalyst system was below the threshold. After much trial and error I did come up with a solution that has worked to keep the light off without disabling any part of the system, and have a correct functioning system to control emissions.It's been 2 weeks now, and still no annoying light.

What was the solution if you don't mind sharing?
