Had a random thought on the way home from work today.
Since it seems that single turbo guys suffer from killing pre-cat (well in this case, pre-turbo) 02 sensors, what kinda leg work would be needed to say, move over to a single bank setup like an N55? Eliminate one whole bank of 02 sensors, can stick the 02 behind the turbo where they'd live longer.
I was out of the dealer by the time the N55 was introduced, and I dont really mess with them all that much, but do they still have bank to bank control like the N54? If so, how is it accomplished now that only one pre-cat 02 reads for the entire engine?
I think the best of both worlds, a MAP based engine management system combined with the single bank of 02 tuning would allow someone with a ST to get much farther than dealing with the factory 02s failing frequently or having to purchase expensive ADV sensors.
Thoughts?
