These are new sensors.......again. And I have moved them downstream from the collectors another 12-18 inches as the cats were removed from the Y when the exhaust was finished up last week. The widebands were in the collectors, but are now just after the collectors in the Y pipe. The widebands seemed to be working OK after a firmware reflash but bank 2 crapped out again after I had it running for a while yesterday, so I wouldn't trust it. It also seems to fluctuate more in the logs than the bank 1 sensor. I tried tuning off a Bank 1 & 2 averaged BEN, but that wasn't working out as well as the averaged STFTs. It actually made things worse. These are fresh injectors as well - still 95lb/hr. No source for the correct offsets, etc.Originally Posted by joecar
You are welcome......I learn new things by looking at log files.
Hmmm... the STFT behaviour is now different...
I don't know if idle will ever be perfect with the lower intake being a large wide open runnerless box, but right now there doesn't seem to be a desired airflow that it particularly likes. Without the spark correction active it will start surging and die.
