I have been using the new setup now for about a week. so far there is only one issue that I noticed with the open element sensor. That is Heat soak.
I find that on a hot 29C day, the heat soak causes the car to not idle. I have since adjusted the base idle to slightly higher but the minute you drive,
the issue went away. I have not logged any data yet as we have distracted driving law and if the cops sees a laptop running in the passanger seat, its
a $250.00 fine.
I do have a AEM X series wideband gauge that sends CAN info to the link for closed loop operation. I also have the stock narrow band O2 removed.
judging from the readings, the open air element is working out really well.
