I don't have a RR yet, but am seriously considering one, so please forgive me if this question is too elementary. I use 2 widebands and use a PID that averages the BENs for VE tuning. I'm pretty much married to this technique, at least below 75 kPa or so, due to the lopsided airflow under vacuum from the twin screw blower. Can RTACS be configured to use custom PIDs?
