Looks like I need two 02 sensors on top of the Longitudinal Acceleration Sensor. I'll probably pick up another rear O2 spacer from Vast while I am at it...

Will this O2 work or do I need to buy something specific for the AMU? http://www.ecstuning.com/stage/images/dis/7072/600/7072.jpg

is your secondary o2 sensor too far out of the flow?

 

I thought the internal resistance too high and heating circuit errors were always a dead sensor

 

100cell cat, i got lots of those errors....the heating circuit error shows if the signal is not strong enough (hence too far out of the flow)....I was able to adjust the length of my adapter, and viola, no errors and it was working....

Remember, all the second 02 sensor does is read a voltage to confirm that B1S1 is working correctly...moving it away from the flow makes it harder to read...

Just my experience...

 

B1S1 is throwing an error too

 

Not enough fuel as determined by the 02 signal....Remember that sharp change at 5700?

 

codes could come from that.....

While it is likely to be bad, you should explore your options fwiw....

 

I was getting the codes just prior to the downpipe install but will check that first if the sensors give me any more problems.

 

I've been having some odd boost problems lately. Haven't really dug into it too much besides swapping in a new temp sensor.

 

Different fuel maps..
