Does anyone have a definitive step-by-step guide on how to get factory-quality closed loop operation after installing long tube headers? I've read the following thread but my calibration has fewer tables than what Gary posted for his Gen3 tables.

I've multiplied my O2 integrator delay by 1.35 (based upon a FB group suggestion) and still have long periods of flatlining both high and low. Do I blindly keep increasing that table until the flatlining stops?
