The influence or consideration of B4206 was never discussed very much if at all in those days. On the tuck tunes of that era, everything was set up to discourage/eliminate open loop operation whenever the NBO2 has come up to temperature. PE wasn't set up in any way from the factory in any way (60 second time delay setting for B3608, among other obstacles). I've never had the time or taken the time to get all of this straightened out, so I'm trying again now.
